The best cordless grease gun for farm equipment is the DEWALT DCGG571B. It pushes 10,000 max PSI at 5.0 oz per minute, hangs on a 42 inch hose, and runs on any DEWALT 20V MAX battery already sitting in your shop. If your packs are Milwaukee M18, the 2646-20 takes that platform instead.
Greasing a tractor used to mean a compressor, a stiff 25 foot air hose, and a coupler that fought you at every fitting. A cordless grease gun replaces all of it with a battery, a trigger, and roughly the same pressure. For farm work that difference matters most at the fittings you cannot drag a hose to.
We spent 2026 season putting ten of the most-reviewed cordless grease guns through the kind of service a farm shop actually demands: PTO driveline U-joints, loader kingpins, zero-turn deck spindles, implement hinges, and track tensioners. Our selection criteria were pressure at the fitting, flow rate on a full machine, hose reach, metering control, and whether the gun fits a battery platform the farm already owns. Last updated October 2026.
If you also run older pump-style guns in the shed, our general grease gun comparison covers the manual and air options side by side.

1. DEWALT DCGG571B – Best Overall Cordless Grease Gun for Farm Work
DEWALT Grease Gun 20V MAX, Cordless Electric Grease Gun 42” Hose, 10,000 PSI, Variable Speed Triggers, Tool Only (DCGG571B)
10,000 max PSI
5.0 oz/min
42 inch hose
8 lbs
Any DEWALT 20V MAX battery
Pros
- Highest rated and most reviewed gun in the group
- 10000 max PSI powers through dried and contaminated zerks
- 42 inch hose reaches fittings without moving the machine
- Variable speed trigger meters output into worn seals
- Runs on any DEWALT 20V MAX pack
- Integrated foot stand and LED work light
Cons
- Heavier than a hand pump at 8 lbs
- Sold as tool only so a battery and charger are separate purchases
- Needs a 90 degree or locking coupler for the tightest fittings
Over 6,300 reviews sit behind this one, and the reason is simple: it does the farm job without ceremony. The 10,000 max PSI motor has no trouble pushing a fresh Zerk of thick EP2 grease into a kingpin that has been sitting since last season, and the 5.0 oz per minute pump clears a full 14 ounce cartridge in under three minutes.
The 42 inch hose is the detail that earns its keep on equipment. On a compact tractor the rear driveline and the loader arms are close together, so the gun can sit on the ground or a track and reach the fitting without you climbing back down.
What separates it from cheaper 20V-compatible guns is the variable speed trigger. On a worn kingpin or a ball joint that has already taken a lot of grease, you feather the trigger and feed a measured dose. A fixed-speed gun either starves the fitting or blows the seal.
Operators on Bobcat Tractor Group threads consistently name DEWALT 20V MAX as the platform they recommend, and the logic is battery compatibility rather than the badge. A farm already owns dozens of 20V packs, so the marginal cost of this gun is the tool itself.
When this gun earns its slot on your equipment
This is the gun I would hand a technician doing a daily walk-around on a mixed fleet: skid steers, a compact loader, zero-turn decks, and UTVs. The combination of pressure, reach, and metering means one tool covers everything from a grease-sensitive spindle to a seized driveline joint.
The air bleeder valve primes the pump quickly after a cartridge change, and the integrated foot lets the tool stand on a deck or the shop floor while both hands work. That foot matters more than it sounds when you are swapping a cartridge in the rain.
Where it falls short on a farm
At 8 lbs it is a solid weight, and holding it overhead under a trailer or reaching into a combine housing gets tiring over a long session. Reviewers also report that it takes 14 ounce 400 g cartridges, which differs from the 450 g size sold in some markets.
The other gap is accessories. The box includes the gun and a shoulder strap, and a locking or 90 degree coupler for the tightest zerks is a separate purchase. Budget for one before you grease a machine in the field.
2. Milwaukee 2646-20 M18 – Best for Reaching PTO Shafts and Track Work
Milwaukee 2646-20 M18 2-speed Grease Gun, Bare Tool
10,000 max PSI
48 inch hose
1-10 pump counter
9 lbs
M18 batteries
Pros
- 48 inch hose is the longest in the group
- Pre-set counter dial delivers repeatable 1-10 pump doses
- Two speeds for metering or bulk delivery
- Lock-on trigger cuts hand fatigue on long sessions
- 5 year tool warranty
- Bare tool works with existing M18 packs
Cons
- No battery or charger included
- Air bleeder can spit grease on the opposite side during first prime
- Hose can weep grease behind the coupler on a failed zerk
The Milwaukee M18 2646-20 is the pick for anyone working around the outside of a machine rather than under it. The 48 inch hose lets the gun rest on a track, a wheel, or the ground while you reach a PTO U-joint, an excavator pin bushing, or a track tensioner at full arm extension.
The grease counter dial is the feature experienced operators talk about most. Most tractor and combine manufacturers specify a pump count per service point, and this gun lets you dial 1 through 10 or run continuous. You follow the book instead of guessing.
Two speeds give you a genuine choice between a slow metered dose at a sealed bearing and fast bulk delivery on a machine that has been sitting in the weather. Combined with a lock-on trigger, a long session on a large machine stops being a hand cramp contest.
Owners of tractors, loaders, and excavators call this their go-to gun, and the 10,000 PSI rating matches the DEWALT at the top of the range. It is also one of the longer-established designs here, with 3,500 reviews behind it and a 5 year tool warranty.
Where the 48 inch hose changes the job
Any service point that forces you to climb, reach over a fender, or fight an air hose is where this gun wins. A skid steer with 20-plus zerks around the loader arm and rear axle can be done standing on the ground with the gun parked on the cab step.
The counter dial also makes repeat service honest. Set three pumps for a kingpin and the same three pumps go in every month, which is the difference between a preventive maintenance schedule that works and one that quietly over-greases seals.
What to plan around
This is a bare tool. If nobody on the farm owns M18 packs, you are buying a battery ecosystem at the same time, and that is where the total cost of ownership shifts.
Reviewers mention two minor realities. The air bleeder expels grease from the port on the opposite side of the button, so the first prime after a cartridge change is messy until you get used to it. And on a failed zerk, residual pressure in the long hose can weep grease behind the coupler, which means wiping the nipple even when the fitting is fine.
3. Lincoln 1884 PowerLuber – Premium Pick With Two Batteries in the Box
Lincoln 1884 PowerLuber 20 Volt Battery Powered Grease Gun with 36″ Hose for Automotive, Agricultural, and Industrial Equipment, 10,000 PSI, Trigger-Operated, 2-Speed, (2) Lithium-Ion Battery Pack
10,000 PSI
2 speed
LCD with flow counter
13.8 lbs
2 batteries and charger
Pros
- 10000 PSI in two speeds handles contaminated fittings
- Two 20V batteries plus a 120V charger are included
- Electronic flow counter shows exactly what you pumped
- Automatic priming with a built-in vent valve
- 36 inch high pressure hose
- 5 year tool and 2 year battery warranty
Cons
- Heaviest premium option here at 13.8 lbs
- Residual hose pressure leaves a grease blob when you disconnect
- Case does not hold optional locking couplers
The Lincoln 1884 PowerLuber is the pick when you want a complete, ready-to-work package on day one. Two 20V packs and a 120V charger are included, so there is no separate battery purchase and no waiting on a second charging ecosystem.
The multi-function LCD is the differentiator. It shows motor speed, battery level, and grease flow, and the electronic counter lets you verify a dose instead of estimating one. On a machine where the manufacturer specifies a volume per fitting, that visibility removes the guesswork.
Pressure is a genuine 10,000 PSI across two speed settings, and owners of heavy machinery report it pushing through dirty, contaminated fittings without stalling. Automatic priming through the built-in vent valve means no bleed screw and no grease down the side of the tool.
Lincoln PowerLuber models come up repeatedly in farm forum threads as a trusted workhorse, and the reasoning is consistent: they pump hard, they meter, and they do not ask you to maintain a compressor to use them.
Why the included batteries matter
For a shop that already runs other 20V tools, two extra packs is convenience. For a shop that does not, it is the difference between owning a grease gun on Tuesday and owning a project. A farm that services its own fleet buys a lot of small tools without a battery, then ends up with a shelf of half-useless bare tools.
The 36 inch high pressure hose gives you real reach around a loader arm, and the 3-point base keeps the gun stable standing upright on the ground or a machine while you work the coupler with both hands.
Where it is the wrong call
At 13.8 lbs this is the heaviest gun in the group, and owners upgrading from smaller guns report it being a chore to hold overhead, such as under a truck bed or high on a combine. If overhead work is most of your greasing, a lighter gun is the better daily tool.
Residual pressure in the hose also leaves a small grease blob when you pull the coupler off a fitting, and the supplied case will not hold optional swivel or locking couplers if you add them later.
4. Ryobi P3410 – Best Value for Fast Bulk Greasing
Ryobi 18V Volt Cordless Grease Gun P3410 (Tool- Only)
7.5 oz/min flow
10,000 PSI
30 inch steel hose
8.28 lbs
18V ONE+ battery
Pros
- 7.5 oz per minute is the fastest flow among the big brand options
- Handles 14.5 oz cartridges or bulk fill
- Steel grease tube resists damage
- Exceptionally well balanced by the handle
- Runs quietly and on any Ryobi 18V ONE+ pack
- Onboard LED work light
Cons
- 30 inch hose is the shortest among the major brands
- Included coupler is stiff to remove by hand
- Only one coupler type in the box
- One isolated report of motor failure after about ten uses
The Ryobi P3410 is the fastest-pumping gun among the big-brand options here at 7.5 oz per minute. On a tractor with 25 to 30 zerks that matters, because the whole service turns into a couple of trigger pulls rather than a coffee break.
Owners greasing mowers, mini excavators, and yard equipment point to the balance. Holding it by the handle, the weight sits forward rather than piling up at the battery end, which is where a lot of battery tools become tiring after twenty minutes.
It accepts a 14.5 ounce cartridge or a bulk fill, and the steel grease tube is more durable than a plastic barrel when a tool gets knocked off a fender. The trigger has no dead spot at the start of the pull, which is what makes a slow metered dose possible on a delicate fitting.
Buyers often note the jump from a 30 minute manual session to a few minutes of trigger work, and they rate the tool higher than its class suggests once they see how much labour it removes.
Best fit for high-count service points
If your greasing routine covers a lot of machines with many zerks each, flow rate is the number that moves. A zero-turn deck alone can carry more fittings than a tractor, and a loader or excavator with pins and bushings can hit 20 points in one pass.
The LED work light also matters more outdoors than indoors. Working a ZT spindle or a track tensioner at dusk, the fitting is often underneath a deck plate, and a hand light means stopping to find it.
Where to buy a coupler before you start
The 30 inch hose is the shortest among the major brand options, so you will reposition the machine more often on large equipment. Owners recommend adding a locking coupler or a right angle tip because the included coupler is stiff to remove by hand, especially with thick grease on the threads.
Only one coupler type is included. Buy a 90 degree and a lock-on before the first big job rather than discovering the gap in a wet field with a ZT spindle half done.
5. Milwaukee 2446-20 M12 – Best Lightweight Gun for Small Equipment
Milwaukee Bare-Tool Milwaukee 2446-20 M12 12-Volt Cordless Grease Gun (Tool Only, No Battery)
Over 8000 PSI
7 cartridges per charge
36 inch hose
7.2 lbs and 14 inch long
Pros
- Lightest Milwaukee option at 7.2 lbs and only 14 inches long
- Up to 7 cartridges per charge is strong runtime for the battery class
- Soft-start trigger ramp meters grease into worn kingpins
- 36 inch flex hose with spring guard
- Air bleeder valve primes quickly
- Bulk filler valve and LED fuel gauge
Cons
- Lowest pressure here at just over 8000 PSI so seized fittings are hard
- No LED work light and no counter dial
- Air bleeder can expel a grease blob on the first prime
- No hard case offered and crevices eventually trap grease
The Milwaukee M12 2446-20 is the small equipment answer. At 7.2 lbs and only 14 inches long, it is the easiest gun here to hold one-handed, which makes it well suited to ATVs, UTVs, small mowers, and anything where you are working at waist height rather than under a machine.
Runtime is the headline number: up to 7 grease cartridges per charge. That is the best in the group for a 12V class and means a full routine service on several small machines without a recharge or a swap.
The soft-start trigger ramp is the detail that makes it safe on old equipment. It ramps pressure up as you pull, so you can feed a measured dose into a worn kingpin or a dry ball joint instead of hitting it with full pressure and blowing the seal.
It holds 14 ounce cartridges or 16 ounces of bulk grease, and the 36 inch flex hose has spring guards at the ends to survive being dragged across concrete and into gravel.
Where the M12 platform fits a farm
Many farms already standardize on M12 for lighter duty tools because the packs are small and cheap to keep in every vehicle. This gun makes that platform useful for greasing, which is a genuine gain rather than a duplicate purchase.
It is also a sensible second gun for a household that has a Milwaukee M18 for hard work. A dedicated small gun means the big tool stays in the truck instead of moving around the property all day.
Where pressure is not enough
Just over 8,000 PSI is the lowest ceiling in this group, and that is the limit. On a fitting that has seized, corroded shut, or packed with dried grease, this gun will stall where a 10,000 or 12,000 PSI unit pushes through.
There is also no LED work light, no two-speed selection, and no counter dial, so metering depends entirely on the soft-start ramp and your trigger control. And on the first prime, hold the suction plunger in or the air bleeder will expel a grease blob.
6. Ecarke 12000 PSI – Best for Bulk and Drum Grease Loading
Ecarke Cordless Grease Gun Compatible with DeWalt 20V Battery, 12000PSI Max Electric Grease Gun, Dual Pistol & in-Line Grip, Works with Bulk & Cartridge Grease, with 39″ Hose & 4 Couplers (Tool Only)
12000 max PSI
8 oz/min flow
39 inch hose
bulk and cartridge
2-in-1 grip
Pros
- 12000 PSI and 8 oz per minute
- Loads 14 oz cartridges plus bulk grease from a drum
- 2-in-1 rotating handle switches pistol and in-line grip
- Four couplers including 90 degree and lock-on are in the box
- Works with existing DEWALT 20V packs
- Shoulder strap and hard case included
Cons
- Build feels lighter than a genuine DEWALT tool
- Air can be difficult to purge and grease can stay in the barrel
- 10.47 lbs is heavy for a work-along gun
- Some accessory quality control misses reported
The Ecarke is built around one idea: if a farm buys grease by the case, cartridges are the wrong format. It loads standard 14 ounce cartridges, but it also takes bulk grease straight from a pail or drum through a T-handle plunger, which drops the cost per ounce of grease on high-volume service.
Specs are strong on paper and reviewers back the flow rate in practice, reporting 8 oz per minute with enough force to tension tracks on a 27 ton excavator. That is a genuinely useful combination for pin and bushing work on heavy equipment.
The 2-in-1 rotating handle is the feature owners praise most. Flip it and you have a pistol grip for confined spaces and a straight in-line grip for reach, which solves the usual problem where a compact gun cannot reach and an extended gun will not fit.
It also runs on DEWALT 20V batteries, so a shop already committed to that platform can add 12,000 PSI capability without buying new packs.
Who bulk loading actually pays off
A shop doing daily or weekly service on a fleet of tractors, loaders, and combines burns through grease fast enough that cartridges become a recurring line item. Bulk loading turns that into a drum purchase and, owners report, a visible drop in cost per ounce.
It also fits a farm that mixes grease types. When a machine needs an EP2 extreme-pressure grease and the next needs a general-duty lithium complex, a bulk gun lets you change products without hunting for the right cartridge.
Where expectations need adjusting
Owners describe the build as lighter than a genuine DEWALT tool, and the plastic body is something to consider if the gun will be dropped on concrete. At 10.47 lbs it is a heavy gun for work you do away from the truck.
The most common complaints are purging air and residual grease in the barrel. Some owners report a hose end that unscrewed rather than locking, so check the fitting before relying on it. Customer service did replace a burst hose quickly, which is worth knowing.
7. Seesii SE-GR01 Ultra – Best for Makita Battery Owners Who Want Batteries Included
Seesii 2-in-1 Electric Grease Gun, 12000 PSI, with 2 Batteries and 48” Hose
12000 PSI
5.3 oz/min
48 inch hose
6.6 lbs
2 batteries and case
Pros
- 12000 PSI working pressure with a 5.3 oz per minute flow
- 48 inch hose reaches most fittings without moving the machine
- Two 2.0Ah batteries plus a charger and case included
- Also accepts Makita 18V packs for flexible power options
- 400cc barrel takes bulk grease or 14 oz cartridges
- Case has a hose organizer to stop tangling
Cons
- Included batteries do not charge on Makita chargers
- Non-locking hose end may need an extra fitting
- Some grease stays in the tube
- One reviewer judged it underpowered under an 18-wheeler
The Seesii SE-GR01 Ultra is a two-birds package for a farm that runs Makita. It comes with two 2.0Ah rechargeable batteries, a charger, and a hard case with a hose organizer, and it also accepts Makita 18V packs if you would rather use the batteries you already own.
Owners with 20 to 30 zerks on tractors and mini excavators report getting through a full machine on a single cartridge with charge remaining. Between the two included packs, a season of routine service does not require a dedicated charging plan.
The 400cc barrel with a 54mm bore accepts bulk grease or a 14 ounce cartridge, and it is rated for NLGI #0, #1, and #2 greases. That covers the range most farm equipment needs, including the thick winter grades.
The 2-in-1 handle configuration is praised for working on both a tractor deck and an excavator boom, and the 48 inch hose means most fittings are reachable without climbing down.
The battery and charger caveat that matters
The tool accepts Makita 18V batteries, but the batteries included in the box do not charge on Makita chargers. If your plan was to run everything off one charger, that assumption breaks, and you need to keep the supplied charger in the mix.
Otherwise the value here is straightforward. Owners rate it as roughly half the outlay of the big-brand tools with comparable pressure output, and the included case with a hose organizer stops the exact kinking problem that shortens hose life.
Where it is not the answer
The hose end screws on rather than locking, and one owner had to buy an additional end fitting. That is a real problem on a fitting that resists removal, because a threaded end can unstick halfway and dump the dose.
Some grease also stays in the tube, and one reviewer judged it underpowered for working under an eighteen-wheeler. For farm equipment in the size range this roundup covers, that is an outlier, but it is a reminder that 5.3 oz per minute is mid-range.
8. DIYtoolifz 3-Speed – Best for Matching Flow to Each Fitting
DIYtoolifz Cordless Grease Gun Compatible with Milwaukee 18V Battery, 12000PSI High Pressure, 3-Speed&Brushless Motor, 9oz/min Flow, 2-in-1 for Cartridge/Bulk Grease, 39.4”Hose&4 Couplers(Tool Only)
12000 PSI
9 oz/min peak
3 speed dial
Milwaukee 18V
39.4 inch braided hose
Pros
- Only gun here with three discrete flow speeds
- Highest peak flow in the set at 9 oz per minute
- Brushless motor runs cooler than brushed types
- Steel-braided burst-proof hose
- Loads cartridges plus bulk grease from pails or drums
- Four couplers plus kickstand and shoulder strap
Cons
- Lowest average rating in the group with several one-star reports
- Some units report a bulk plunger too large for a standard cartridge
- One review reports very slow grease delivery
- Heaviest tool here at 11.48 lbs
The three-speed dial is the reason to look at this gun. Low delivers about 5 oz per minute, medium about 7, and high about 9, so you can match output to the fitting instead of running every service point at maximum. On a machine with 25 zerks of mixed sensitivity, that is a real grease saving.
Peak flow of 9 oz per minute is the highest in this group, and the steel-braided hose is a genuine upgrade over a plain rubber hose if the gun lives in a truck bed. Milwaukee 18V compatibility means no new packs, with 4.0Ah or higher recommended.
The kit is unusually complete: four couplers including a 90 degree, a lock-on, a pointed tip, and a standard fitting, plus an extension pipe, wrenches, a shoulder strap, a kickstand, an LED, and a blow-molded case. Owners mention the strap noticeably reducing fatigue on long jobs.
It loads 14 ounce cartridges and bulk grease from pails or drums, and the brushless motor should run cooler and last longer than a brushed design under sustained load.
What three speeds are actually worth
Grease is not free and over-greasing a sealed bearing is a real failure mode. A three-speed setup lets you run low on a spindle bearing, medium on a kingpin, and high on a driveline U-joint during the same pass, then come back and confirm with a single slow pump.
Owners working on tractors with 20 to 30 zerks call the speed control a real upgrade over manual guns, and the bulk loading cuts grease cost on a fleet this size.
Where the reviews hold you back
This is the lowest-rated gun in the group at 4.3, and the reason is a cluster of one-star reports about units that would not pump at all after correct setup. That is a failure mode you cannot live with in the field, so treat it seriously.
Some examples report a bulk plunger too large to fit a standard cartridge, meaning cartridge mode may not work on every build, and one review reports very slow grease delivery. It is also the heaviest gun here at 11.48 lbs.
9. TaskStar Lock-On Kit – Best Lightweight Kit for Field and Barn Use
TaskStar Electric Grease Gun with Lock-On Trigger for Effortless Greasing
10000 PSI
5 oz/min
39.4 inch hose
5.6 lbs
2 batteries and strap
Pros
- Lightest complete kit here at 5.6 lbs
- Lock-on trigger removes the need to hold the trigger down
- Lock coupler seats securely and resists popping off
- Two rechargeable batteries and a charger included
- Case with slotted hose holder keeps everything packed
- Shoulder strap for carrying around a barn or field
Cons
- Grease port opening is awkwardly placed and can shift in tight spots
- Included coupler does not always sit flush
- 5 oz per minute is lower than the Ryobi and Ecarke flow rates
The TaskStar is the most complete lightweight package in this roundup. Two rechargeable batteries, a charger, a carrying case with a slotted hose holder, and a shoulder strap all arrive together, which means no separate battery ecosystem and no buying a bag to move it around.
At 5.6 lbs it is the lightest gun here, and that is the point. When you are walking a barn, a fence line, or a field of implements rather than standing at a machine, weight decides whether you do the job now or later.
The lock-on trigger lets you set the gun running while you attach the coupler, which matters on a fitting that needs both hands. The quick-release lock coupler is the other half of that: it seats firmly on the Zerk and resists popping off under pressure, which is a persistent annoyance with plain couplers.
Owners say it handles thick grease without bogging down, and one full charge is rated to grease up to 10 tractors. Farmers, truckers, and mechanics describe it as matching the name-brand guns at a fraction of the outlay.
Where a light kit genuinely helps
Outbuilding and field maintenance is the case for this gun. When the machine is outside, the compressor is inside, and the air hose is the reason the job gets skipped, a self-contained kit that fits over a shoulder is the difference between a scheduled service and a deferred one.
Two batteries means you can work through a full session and still have a charge ready for the next call, and the slotted hose holder stops the hose tangling, which is what quietly shortens hose life.
Where you will notice the trade-off
At 5 oz per minute this is a mid-range flow rate, well below the Ryobi at 7.5 or the DIYtoolifz peak of 9. On a machine with 30 zerks you will be working the trigger longer than with a high-flow gun.
The one repeated complaint is the grease port opening. It is awkwardly placed and can shift or pop open while you are maneuvering in a tight space, and the included coupler does not always sit flush on every fitting, so some owners fit an aftermarket tip.
10. ATIVERE 10,000 PSI – Most Versatile for DeWALT 20V MAX Owners
ATIVERE Grease Gun Cordless 10000 PSI for DeWalt 20V Max 12in Spring Hose
10000 PSI
12 inch spring hose plus 6 inch tube
6-jaw lock coupler
6.65 lbs
DEWALT 20V MAX
Pros
- Light at 6.65 lbs while still producing 10000 PSI
- Runs on existing DEWALT 20V MAX packs
- One-handed operation leaves a hand free to steady the hose
- 6-jaw ultra-lock coupler grips the zerk and resists slippage
- LED light and auto-bleed function simplify setup
- Bulk grease and 14 oz cartridge capacity
Cons
- 12 inch hose plus a 6 inch tube is the shortest reach in the group
- Does not feel as heavy duty as professional models
- One report of connector failure and bearings dropping out
- Two battery tabs give less precise charge feedback
The ATIVERE is the simplest way to add a cordless grease gun to a DEWALT 20V MAX shop. It runs on the same packs as the rest of the platform, produces a genuine 10,000 PSI, and takes both 14 ounce cartridges and bulk grease.
At 6.65 lbs it is one of the lighter guns here, and the one-handed operation design means your other hand can steady the hose or hold onto a machine while you work.
The 6-jaw ultra-lock coupler is worth noting. It grips the Zerk firmly and resists slippage at pressure, which addresses the most common reason a fitting ends up with a half-pumped dose of grease and a wrist full of the old stuff.
Most owners confirm it works reliably for routine farm, skid steer, and general equipment maintenance, and they cite simple setup, steady flow, and a comfortable grip.
Where a short hose forces compromise
The 12 inch spring hose plus a 6 inch rigid tube is the shortest reach in this roundup by a wide margin. On a large machine you will be climbing on and off constantly, and the point of a cordless gun is partly to avoid that.
So this one works best close to the tool: UTVs, small tractors, skid steers at the service points you can reach, and general shop maintenance. It is a companion to a bigger gun, not a replacement for one.
Where the budget shows
Owners report it does not feel as heavy duty as the professional models, and one review describes the connector falling apart with ball bearings dropping out, which is a single report but a serious one given what you are asking the tool to do.
It also uses two battery tabs for feedback, so the charge reading is less precise than on four-tab packs. Plan the top-up before a long service rather than trusting the indicator.
How to Choose a Cordless Grease Gun for Farm Equipment
The short answer on pressure: for routine farm service, 8,000 PSI is enough, 10,000 PSI is the sweet spot for dirty or neglected fittings, and 12,000 PSI is overkill for most tractors but useful on track tensioners and seized pins. Most agricultural zerks are rated well below 10,000 PSI, so the number that decides most purchases is not the peak rating.
Flow rate is the more useful figure for a farm. A 5 oz per minute gun takes roughly three minutes to move a 14 ounce cartridge; a 9 oz per minute gun does it in about ninety seconds. On a 30-zerk machine that difference compounds into a meaningful part of the day.
Match the gun to the battery platform you already own
This is the highest-return decision you will make. A DEWALT 20V MAX owner can choose from the DCGG571B, the Ecarke, or the ATIVERE without buying a single new pack. Milwaukee M18 owners can pick the 2646-20 for its counter dial and long hose, or the DIYtoolifz for three-speed control. Ryobi 18V ONE+ owners have the P3410. Makita shops can use the Seesii, keeping in mind the included batteries need their own charger.
Forum consensus across equipment operator groups is consistent on this point: platform match matters more than the brand on the gun. A lesser tool on batteries you already charge every night beats a flagship tool that introduces a fourth charger.
Hose length, couplers, and bypass grease
Hose length decides how much climbing you do. Thirty inches is workable for small machines, forty to forty-eight inches covers tractors, loaders, and excavators without repositioning. The counterweight to a long hose is that residual pressure stays in the line, so a grease blob appears when you disconnect.
Buy a 90 degree coupler and a lock-on coupler regardless of which gun you choose. Angled fittings are common on machinery, and a lock-on coupler stops the gun popping off at pressure, which is both a safety and a mess issue.
On bypass grease: most cordless guns vent rather than recirculate, so a high-pressure application like a PTO cross or a track tensioner can push grease out of the bypass port. That is a normal behaviour, but a pressure return valve that catches the escaping grease is the accessory operators add.
Cordless vs air-powered vs hand pump in a farm shop
An air gun still wins on sustained bulk work if a compressor is already running, and it never runs out mid-service. Its costs are the stiff hose, the coupler failures, and the daily friction of a machine that leaks air down.
A hand pump is unbeatable for one fitting in a cold shed and free to own. It loses badly across twenty zerks, and it is the reason so many farm services get skipped.
A cordless gun wins the middle ground: no compressor, no hose to fight, and a real speed increase on routine service. The case against it is battery logistics and the fact that a high-flow gun can outpump your grease supply, so keep cartridges or a bulk drum on hand before a season.
One last practical note. Purge the gun after every use, keep cartridges sealed, store the hose loose rather than coiled tight, and lock the trigger for transport. Dried grease inside a barrel is the number one owner complaint in the field, and it is entirely avoidable.

Frequently Asked Questions
Who makes the best cordless grease gun?
For farm work the DEWALT DCGG571B leads the group, combining 10,000 max PSI, 5.0 oz per minute flow, a 42 inch hose, and a variable speed trigger for metering. Milwaukee 2646-20 is the alternative choice if your shop already runs M18 packs, mainly for its 48 inch hose and repeatable 1-10 pump counter dial.
What PSI do I need for a grease gun?
For routine service on tractors, loaders, and mowers, 8,000 PSI is generally enough. Dirt and dried grease raise the requirement, so 10,000 PSI is the practical target for farm equipment. Above that, 12,000 PSI mainly helps on track tensioners and seized pins. Flow rate in ounces per minute matters more than peak pressure across a full machine.
Are battery-powered grease guns worth it?
Yes, once a machine has more than a few service points. Operators describe turning a 30 minute manual job into two or three minutes of trigger work. The wins are speed, no compressor hose to drag around, and consistent metering. The trade-offs are battery logistics, grease cost if flow outpaces your supply, and pressure that may not clear a badly seized fitting.
What is the best cordless grease gun for zero-turn mowers?
A deck spindle needs a metered dose rather than maximum flow, so a variable speed trigger or a multi-speed dial is the deciding feature. The DEWALT DCGG571B and the DIYtoolifz 3-Speed both give that control, and the Ryobi P3410 wins on flow when a whole deck of 25 or more fittings needs serviced in one pass. A 30 inch or longer hose keeps you off the ground less.
Which is better, DeWalt or Milwaukee grease gun?
It comes down to the batteries and the counter. The Milwaukee 2646-20 offers a pre-set 1-10 pump counter dial and a 48 inch hose, which suits operators who follow manufacturer pump counts and work around big machines. The DEWALT DCGG571B offers variable speed control, which suits anyone dosing grease into worn seals and ball joints. Both run on batteries most farms already own.
Final Verdict for Farm Equipment Greasing in 2026
The DEWALT DCGG571B is our cordless grease gun for farm equipment in 2026. Ten thousand max PSI, 5.0 oz per minute, a 42 inch hose, and a variable speed trigger cover everything from zero-turn spindles to loader kingpins, and it runs on the 20V MAX packs most shops already charge nightly.
Milwaukee M18 owners should take the 2646-20 for the 48 inch hose and repeatable pump counts. The Lincoln 1884 PowerLuber is the pick when you want two batteries and a charger in the box. Ryobi ONE+ owners get the fastest big-brand flow in the P3410. Bulk grease users should look at the Ecarke, and light field work is handled best by the Milwaukee M12 or the TaskStar kit.
Whichever you choose, buy a 90 degree coupler and a lock-on coupler with it, and purge the gun after every use. For the wider shed, our cordless nail gun picks cover the other end of the maintenance list.
