Large rear wheel lawn mowers use bigger rear wheels and rear-wheel drive to provide better traction and stability on uneven terrain, slopes, and rough grass compared to standard mowers.
For the full breakdown, see our best Large Rear Wheel Lawn Mower guide.
If you’re pushing a mower up a hill or through bumpy grass, you’ve felt the back end slip or the front wheels dig in. Large rear wheel mowers solve that. These walk-behind machines combine larger rear wheels with rear-wheel drive (RWD) to pull the mower forward, keeping the cutting deck stable and reducing arm fatigue.
What Makes It a Large Rear Wheel Mower?
The defining feature is the size difference between front and rear wheels. Most models use 7–8 inch front wheels paired with 10–11 inch rear wheels, lifting the back higher for better clearance and grip. Manufacturers typically pair large rear wheels with RWD. Unlike front-wheel drive (FWD) mowers that pull from the front, RWD pushes from the back, keeping drive wheels planted under the engine’s weight for more consistent traction and less skidding on wet grass or loose soil.
What Large Rear Wheel Mowers Are Best For
They excel on sloped lawns, rough terrain, and thick grass that bogs down standard mowers. Larger rear wheels also roll over tree roots and bumps without stopping. For flat, manicured lawns, a large rear wheel mower is overkill — but for yards with any grade or rough patches, each mowing is noticeably easier.
Key Differences Between Models
Cutting widths range from 21 to 28 inches. Engines span 140cc to 196cc. Height-of-cut adjustments vary: the Lawn-Boy 17752 adjusts from 1.25 to 3.75 inches, while other models go from 1 inch to 4 inches.
| Model | Rear Wheel Size | Engine & Cutting Width |
|---|---|---|
| DEWALT 12AVP2RF039 | 11 inches | 196cc engine, 21-inch deck, RWD |
| Lawn-Boy 17752 | 8 inches | 140cc engine, 21-inch deck, variable-speed RWD |
What to Check Before Buying
Large rear wheels are not a magic bullet. A mower labeled “high rear wheel” but using FWD won’t match true RWD on slopes — read specs carefully for “RWD.” Also check height adjustment range: the Lawn-Boy maxes at 3.75 inches, fine for cool-season grasses but possibly too low for warm-season varieties in the deep south. Finally, consider terrain. Large rear wheels help on moderate slopes but won’t replace zero-turn or riding mowers on steep hills over 15–20 degrees.
FAQs
Is a large rear wheel mower the same as a rear-wheel drive mower?
Not always. Some have large rear wheels but use FWD or manual push. For slope performance, you want both large rear wheels and RWD. Check product specs for “RWD.”
Can a large rear wheel mower handle hills?
Yes, on moderate slopes up to 15–20 degrees, they outperform standard mowers. For steeper hills, use a zero-turn or riding mower for safety.
What engine size do I need for a large rear wheel mower?
Engine displacement ranges from 140cc to 196cc. A 140cc engine is fine for level yards; 190cc+ handles thicker grass and slopes. Match power to your lawn’s conditions.
