Our acreage picks
TaskStar Cordless Electric Grease Gun with 2 Batteries and 40-Inch Hose
A cordless electric grease gun stating up to 10000 PSI and 5 oz/min flow, with a lock-on trigger, 2 batteries and a 40 in hose.
Who it's for: anyone greasing a fleet of mowers, trailers and tractors who wants to skip hand pumping.
Who should skip it: anyone who wants a stated warranty term or a lighter tool, since the listing states neither.
Read the full review
The listing states a cordless electric grease gun delivering up to 10000 PSI at 5 oz/min, with a lock-on trigger, 2 lithium ion batteries, a 40 in hose and an LED light, and 14 oz capacity for tractors, trucks and equipment. One contradiction: the bullets say the gun weighs 5.6 lbs while the spec table lists 6.16 pounds, so the guide reports both. The 5x faster claim is the maker's marketing.
Pros
- Up to 10000 PSI stated, the highest pressure here
- 5 oz/min flow rate with a lock-on trigger for continuous greasing
- 2 rechargeable batteries included for longer runtime
- 40 in hose and LED light for reaching fittings
Cons
- No warranty term is stated
- Bullets say 5.6 lbs while the spec table says 6.16 pounds
- Heaviest gun here at either stated weight
- Electric complexity for a job a manual gun also does

The title, bullets and spec table agree on the pressure and capacity. The listing names tractors, PTO axles and lawn mowers among its uses.
Pros

- 14 oz capacity with a 6-jaw coupler upgrade included
- 18 in spring hose plus two 12 in hoses and injector needles

Read the full review
The listing states a pistol grip grease gun with 14 oz capacity, 3 filling methods (cartridge, fill pump, bulk), an 18 in spring-loaded hose and a full accessory kit in die-cast aluminum. One contradiction: the title says 7000 PSI while the bullets claim 8000 PSI as the max working pressure, so the guide follows the title. The listing names lawn mowers, marine trailers and automotive axles among its uses.
Pros
- 3 filling methods: cartridge, fill pump and bulk
- 14 oz capacity with a full accessory kit and storage bag
- 18 in spring-loaded hose for tight spots

Who it's for: anyone who wants a complete mini kit in one box.
Who should skip it: anyone greasing a whole fleet, since 3.52 oz runs out fast.
Read the full review
The listing states a mini pistol grip grease gun with 3.52 oz capacity and 3000 PSI max working pressure in die cast aluminum, with two 4-jaw couplers, a sharp nozzle, extension adapter, a 12 in spring flex hose, 3 oz of grease, a glove and a cleaner.

Who should skip it: anyone who needs a zerk coupler or a stated pressure figure.
Read the full review
The listing states a mini grease gun with a needle nozzle for air tools and flush-type fittings, 3 oz capacity and one-hand operation, with a 1 yr warranty on material and workmanship. One contradiction: the bullets say the weight is 1 lb while the spec table lists 9.6 ounces, so the guide reports both.

Buying guide: the best grease gun for home use
Manual pistol grip or cordless electric
Four of the five here are manual pistol grip guns: you squeeze the handle and the plunger pushes grease. The TaskStar is the cordless electric exception, with a lock-on trigger for continuous flow and 2 rechargeable batteries included. The listing claims it is 5x faster than manual guns and states a 5 oz/min flow rate; treat both as the maker’s claim. For a few zerks on one mower, a manual gun is plenty. For a fleet of mowers, trailers and tractors, the electric gun saves hands. See also our best grease gun roundup for mowers and equipment.
Pressure figures, as stated
Stated max working pressure runs from 3000 PSI on the SHALL to 7000 PSI on the KRETLAW and up to 10000 PSI on the TaskStar. The Astro mini states no pressure. Read these as the maker’s claim and compare them side by side rather than as engineering data. One flag: the GETLMUL title says 7000 PSI while its bullets claim 8000 PSI, so its review notes the mismatch and the comparison table follows the title.
Capacity and filling
The KRETLAW, GETLMUL and TaskStar each list 14 oz capacity, the standard cartridge size, so one cartridge handles a full round of the property without a refill. The SHALL holds 3.52 oz and the Astro holds 3 oz, both one-hand minis for quick hits and tight spots. The GETLMUL lists 3 filling methods: cartridge, fill pump and bulk. The Astro fills differently: pack grease in the bottom, reinstall the base cap, and push up against the inside plate with a screwdriver to feed grease to the nozzle.
Hoses, couplers and nozzles
The hose decides whether you can reach the fitting. The TaskStar lists a 40 in hose, the KRETLAW lists an 18 in spring hose plus two 12 in hoses, the GETLMUL lists an 18 in resin flex hose, and the SHALL lists a 12 in spring flex hose. Couplers matter too: the KRETLAW includes a 6-jaw coupler plus a 4-jaw, the SHALL includes two 4-jaw couplers, and the GETLMUL includes a quick locking coupler. The Astro skips the coupler entirely and ships a needle nozzle for flush-type fittings on air tools. Match the end to the fittings you own; our riding mower maintenance guide walks through where the zerks hide.
Read the warranty line
Only one listing here states a warranty term: the Astro lists 1 yr on material and workmanship. The other four state no warranty term at all, so the warranty column in the comparison table reads “Not stated” for them. A stated term is worth more than a durability claim in the bullets, but one year on a hand tool is modest; keep the receipt either way.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- A mini gun suits a small kit: the Astro holds 3 oz and the SHALL holds 3.52 oz, both one-hand designs for quick zerk hits around the mower.
- A 14 oz gun covers mowers, trailers and tractors without refills: the KRETLAW, GETLMUL and TaskStar each list 14 oz capacity.
- Store the kit where you service the equipment: the SHALL and GETLMUL include kit extras like gloves, caps and a storage bag, and the TaskStar lists a shoulder strap for carrying.
- Match the end to the fitting: 4-jaw and 6-jaw couplers are listed across these kits, and the Astro’s needle nozzle is for flush-type fittings.
The Acre Score explained
The Acre Score weighs five factors: performance (stated pressure, flow, capacity and kit completeness), build quality (construction and materials), value (specs for the class), safety (stated safety features) and warranty. None of these listings states a safety certification or safety feature, so every gun here scores zero on safety; the ranking comes from the other four. Only the Astro states a warranty term, 1 yr on material and workmanship.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| TaskStar Electric | 9.6 | 34 | 21 | 21 | 0 | 0 |
| KRETLAW K180005 | 9.5 | 32 | 21 | 22 | 0 | 0 |
| GETLMUL 14-Oz | 9.5 | 30 | 21 | 21 | 0 | 0 |
| SHALL Mini Kit | 9.5 | 29 | 21 | 21 | 0 | 0 |
| Astro 101 Mini | 9.4 | 26 | 19 | 19 | 0 | 2 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
FAQ: mowing large lots
What grease gun capacity do I need for home use?
It depends on how many zerks you service. The 14 oz guns here, the KRETLAW, GETLMUL and TaskStar, take a standard cartridge and handle a full round of mowers, trailers and tractors without a refill. The 3 oz Astro and 3.52 oz SHALL are minis for quick hits and tight spots, not for a whole fleet.
What does the PSI figure on a grease gun mean?
It is the maker’s stated max working pressure: 3000 PSI on the SHALL, 7000 PSI on the KRETLAW, and up to 10000 PSI on the TaskStar. Treat each figure as the maker’s claim. The GETLMUL lists 7000 PSI in the title and 8000 PSI in the bullets, a mismatch its review calls out.
Do these kits include the couplers and hoses?
Yes, except the Astro. The KRETLAW includes a 6-jaw and a 4-jaw coupler with three hoses, the SHALL includes two 4-jaw couplers and a 12 in hose, and the GETLMUL includes a quick locking coupler and an 18 in hose. The TaskStar includes a 40 in hose. The Astro ships with a needle nozzle instead of a coupler.
Can I use a grease gun on a riding mower?
The SHALL, KRETLAW and GETLMUL listings each name lawn mowers among their uses, and mower deck spindles and front axles are standard zerk points. Check your mower’s manual for the fitting locations and the grease type it calls for. See our lawn tractor maintenance guide for the full routine.
How do you fill the Astro 101 mini grease gun?
Per its bullets: pack the bottom side with grease, reinstall the base cap, then push up against the inside plate with a screwdriver or similar tool to feed grease up to the nozzle and pressurize it. Apply additional pressure to the inside plate occasionally as needed while you work.
