A sloped back lot with a long fence line and a gate too narrow for a rider leaves a walk-behind that pulls itself as the sensible choice.

We compared self-propelled mowers by drive type, deck, cutting heights, engine or battery and warranty, using only what each listing publishes, and we mark where a listing stays silent.

How to choose the best self propelled mower under 600
Drive type: rear-wheel, front-wheel or variable speed
Drive type decides how the mower behaves on slopes and uneven ground. The Greenworks and PowerSmart mowers state rear-wheel drive, which their listings tie to traction on slopes. The SENIX mower states front-wheel drive with 8-inch front and 11-inch rear wheels, and its listing says it suits sloped lawns. The Wild Badger mower states a variable-speed drive that adjusts to walking pace, and its listing speaks to gentle slopes. The BILT HARD mower states a fixed walking speed with no variable control. For larger ground with a battery drive, our battery self-propelled mower for large yards roundup compares more battery options.
Battery or gas
Two listings run on battery and three run on gas, and the split matters for storage and refueling. The Greenworks mower runs on a 40V 5.0Ah battery with a charger, and the Wild Badger mower runs on two 40V 4.0Ah batteries with a fast charger and a stated runtime of up to 88 minutes total. The gas mowers state 170cc engines on the SENIX and PowerSmart listings and a 201cc engine on the BILT HARD listing. Only the Wild Badger listing states a runtime figure, so battery buyers who need a stated runtime should start there.
Cutting heights and clipping modes
Cutting height ranges are stated on four of the five listings, and the Greenworks listing states none. The ranges run from a low end of 1.18 inches on the Wild Badger to a high end of 3.9 inches on the PowerSmart, with the BILT HARD listing offering the most height positions at 8.
| Mower | Cutting heights | Clipping modes |
|---|---|---|
| Greenworks 40V SP | Not stated | Mulch, bag, side discharge, turbo leaf pickup |
| Wild Badger 40V SP | 1.18 to 3.55 inches, 7 positions | Bagging, mulching, side discharge, rear discharge |
| SENIX Gas SP | 1.25 to 3.75 inches, 6 positions | Mulching, side discharge, rear bagging |
| BILT HARD Gas SP | 1.2 to 3.75 inches, 8 positions | Mulching, rear bagging, side discharge |
| PowerSmart Gas SP | 1.5 to 3.9 inches, 6 positions | Bagging, mulching, rear discharge |
Read the warranty line
Three listings state a warranty term and two state none. The Greenworks listing states a 3-year limited tool and battery warranty, the Wild Badger listing states a 3-year limited warranty, and the SENIX listing states a 2-year limited warranty. The BILT HARD and PowerSmart listings state no warranty term, so their scores rest on engine, deck and drive alone. A stated term matters more for a mower that will see daily use across a season than for one kept for occasional trims.
Matching It to Your Property
- Slopes: rear-wheel drive is stated on the Greenworks and PowerSmart mowers, front-wheel drive on the SENIX, and variable-speed drive on the Wild Badger for gentle slopes.
- Ground: the SENIX listing speaks to 1/3 acres yards, while the Wild Badger listing speaks to medium-to-large lawns and open areas.
- Power: gas mowers state 170cc or 201cc engines, while battery mowers state 40V batteries with a charger included.
- Storage: the SENIX bag holds 16 gallons and the PowerSmart bag holds 1.4 bushels, per their listings, and all five list a 21-inch deck.
Turn rise and run, or a phone level reading, into degrees and percent, then compare it with typical mower slope ratings.
Walk the area first and clear stones, sticks, wire and toys. Wear eye and hearing protection, long pants and sturdy closed footwear, mow across slopes with a walk-behind (not up and down), and never pull a running mower toward you. Keep kids and pets well away. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty. For walk-behind mowers, safety means a stated slope rating, operator presence control or other stated safety feature, and none of these listings states a safety certification, so safety scores zero across the group. Three of the five listings state a warranty term. How we pick explains the weights.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Greenworks 40V SP | 9.6 | 32 | 22 | 21 | 0 | 4 |
| Wild Badger 40V SP | 9.6 | 32 | 21 | 21 | 0 | 4 |
| SENIX Gas SP | 9.5 | 29 | 21 | 20 | 0 | 3 |
| BILT HARD Gas SP | 9.5 | 30 | 21 | 20 | 0 | 0 |
| PowerSmart Gas SP | 9.5 | 29 | 21 | 20 | 0 | 0 |
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.
