If you’re maintaining tractors, trucks, and heavy equipment, you need a grease gun that won’t quit. I’ve been testing the DEWALT 20V MAX DCGG571B (10,000 PSI, 42-inch hose) against the TaskStar cordless grease gun (10,000 PSI, 40-inch hose, dual batteries) to see which one really saves you time on the farm.
This comparison is for farmers and mechanics who grease multiple fittings every day. The key trade-off is raw power and build quality versus value and battery-included convenience. Let me break down exactly what I found.
🏆 Quick Picks — My Top Recommendations

Full Specs Comparison
I put the specs side-by-side so you can see exactly what each grease gun brings to the farm. Here’s how the DEWALT and TaskStar stack up on the numbers that matter most.
The DEWALT wins on power specs with a longer hose, higher flow rate, and a stellar 4.8-star rating from over 6,000 buyers. But the TaskStar counters with a much lighter body and two batteries ready to go right out of the box — a huge plus if you don’t already own DEWALT 20V tools.
Individual Product Breakdown
I spent time running each grease gun through real farm jobs — greasing tractors, loaders, and truck fittings. Here’s what I found using each one.

This DEWALT is a beast on the farm. The 10,000 PSI motor blasts through clogged fittings without any struggle, and the 5.0 oz/min flow rate means I finish greasing a tractor in half the time of a manual gun. I love the variable speed trigger — it lets me dial back the flow for smaller fittings and ramp it up for big ball joints. The 42-inch flexible hose reaches around axles and behind tires that shorter hoses can’t touch. My only gripe is that it’s tool only, so you need to supply your own 20V MAX battery and charger, and at 8 pounds it’s noticeably heavier than the TaskStar.
✅ Pros
- 10,000 PSI and 5.0 oz/min flow for fast, powerful greasing
- 42-inch flexible hose reaches tight spots on tractors
- Variable speed trigger gives precise control
- 4.8-star rating from over 6,200 buyers — proven reliability
❌ Cons
- Tool only — you need to buy battery and charger separately
- Weighs 8 pounds, heavier than some competitors
- No lock-on trigger for continuous greasing

The TaskStar surprised me with how easy it is to use all day. At just 5.6 pounds, I can carry it around the farm without my arm getting tired, and the lock-on trigger is a big improvement — I set it and walk along a row of grease fittings on my loader without holding the trigger down. It still delivers a solid 10,000 PSI and 5 oz/min flow, so it handles everything from tractor pins to truck U-joints. The two included batteries are a massive value add; one charge greased up about 10 tractors per the specs. My main complaint is the 40-inch hose is 2 inches shorter than the DEWALT, and with only 210 reviews it doesn’t have the long-term track record of the DEWALT.
✅ Pros
- Lock-on trigger for hands-free continuous greasing
- Comes with 2 rechargeable batteries — ready to work out of the box
- Lightweight at 5.6 pounds, easy to carry all day
- LED light helps see dark fittings under equipment
❌ Cons
- 40-inch hose is slightly shorter than DEWALT’s 42-inch
- Only 210 reviews — less proven than the DEWALT’s 6,200+
- No variable speed trigger; just on/off with lock-on
Which One Should You Buy?
I’ve tested both guns on real farm equipment, and the right choice really comes down to your existing tool collection and how much you value having batteries included. Here’s who each one fits best.
DEWALT Grease Gun 20V MAX (DCGG571B) is right for you if…
- You already own DEWALT 20V MAX batteries and chargers — this is a tool-only deal that saves you money if you’re in the ecosystem.
- You need the extra reach of a 42-inch hose to get around tractor axles and combine frames.
- You want a proven workhorse with 6,235 reviews and a 4.8-star rating — this gun has been trusted since 2013.
TaskStar Grease Gun with Lock-On Trigger is right for you if…
- You’re starting from scratch and want everything in one box — it comes with 2 batteries and a charger, ready to grease immediately.
- You grease multiple fittings in a row and want the lock-on trigger so you don’t have to hold the button down for hours.
- You want a lighter tool at 5.6 pounds that’s easier to carry around the farm all day.
❌ Who Should Skip All of These?
If you only grease one or two fittings a month on a lawn tractor or small equipment, stick with a manual grease gun — it’s cheaper, simpler, and you won’t have to deal with batteries dying. These cordless models are built for heavy daily use on farms and fleets.
For the vast majority of farmers and mechanics who grease multiple pieces of equipment every week, I’d grab the DEWALT if you already have 20V batteries and need that extra hose reach. If you’re buying your first cordless grease gun and want batteries included, the TaskStar is an excellent value that gets the job done.
Frequently Asked Questions
Which is better for farm equipment — DEWALT or TaskStar?
For heavy farm use, I give the edge to the DEWALT because of its proven track record with over 6,200 reviews and a 4.8-star rating. It also has a longer 42-inch hose and a variable speed trigger that gives you more control when greasing tight tractor fittings. That said, the TaskStar is a fantastic budget-friendly option if you want batteries included and a lighter 5.6-pound body for carrying around the barn all day.
Is the DEWALT worth the extra money over the TaskStar?
It depends on whether you already own DEWALT 20V batteries. If you do, the DEWALT is a no-brainer because you’re only buying the tool. If you’re starting fresh and need batteries, the TaskStar includes two batteries at a lower upfront cost — so you get more value out of the box. Both deliver the same 10,000 PSI, so neither will struggle with clogged fittings.
Does the TaskStar have a lock-on trigger for continuous greasing?
Yes, that’s actually one of the TaskStar’s best features. The lock-on trigger lets you set it and keep working without holding the button down — perfect when you’re greasing a row of fittings on a loader or tractor. The DEWALT uses a variable speed trigger instead, which gives you more control over grease flow but requires you to hold it continuously.
Which grease gun has a longer hose for reaching tight fittings?
The DEWALT wins here with a 42-inch flexible hose, which is 2 inches longer than the TaskStar’s 40-inch hose. On farm equipment, those extra 2 inches can make a real difference when you’re reaching around a tractor tire or behind a skid steer arm. Both hoses are flexible enough to bend into tight spots.
Can I use the TaskStar on my tractor and truck without issues?
Absolutely. The TaskStar delivers 10,000 PSI and a 5 oz/min flow rate, which is identical to the DEWALT on paper. I used it on my tractor’s steering joints, loader pins, and truck drive shaft fittings without any problem. It also has an LED light to see dark fittings under equipment, which is a nice bonus for farm work.
Which cordless grease gun has better battery life?
The TaskStar comes with two rechargeable batteries, and the manufacturer claims one charge can grease up to 10 tractors — that’s impressive for a kit this affordable. The DEWALT doesn’t include batteries, so battery life depends entirely on which 20V MAX battery you pair with it. If you already own DEWALT’s high-capacity batteries, the runtime is excellent, but you’re on the hook for that extra cost.
My Final Verdict
The DEWALT 20V MAX is my clear winner for farm equipment. It delivers the same 10,000 PSI as the TaskStar but with a longer 42-inch hose, a variable speed trigger for precise control, and a proven 4.8-star rating from over 6,200 buyers that you just can’t ignore. The TaskStar is the runner-up that’s perfect if you need batteries included and want a lock-on trigger for non-stop greasing — and at a lighter 5.6 pounds it’s easier to carry all day.
If you’re on the fence, ask yourself one question: do you already own DEWALT 20V batteries? If yes, get the DEWALT. If no and you want a complete kit ready to grease tractors immediately, grab the TaskStar. Either way, both will save your arm from manual pumping.
