Mowing uneven terrain or hilly yards can often be frustrating with standard push mowers, which struggle with stability and traction on slopes, potentially slipping or failing to cut evenly.
If you are faced with thick grass or inclines, a reliable solution is necessary for maintaining a tidy yard safely and efficiently.
Rear Wheel Drive (RWD) lawn mowers are the preferred choice for sloped or uneven landscapes because they offer enhanced grip and control.
When tackling tough conditions, models featuring strong engines, wide cutting decks, and variable speed controls are engineered to deliver consistent performance.
We have evaluated performance on steep inclines, dense grass, and extended use, drawing on hands-on testing and user feedback to identify the most dependable RWD machines for 2025.
1. YARDMAX 22 in. 201cc CVT RWD Mower – Best Overall

Choosing the Right Rear Wheel Drive Lawn Mower: A Detailed Buying Guide
Rear Wheel Drive (RWD) lawn mowers are widely favored for their superior traction and maneuverability, especially when dealing with uneven terrain or hills. Selecting the ideal model requires evaluating several critical components.
Engine Power & Size
The engine is considered the heart of the lawn mower. For smaller, flatter yards (under 1/4 acre), an engine in the 140cc to 150cc range, such as the B&S 140cc in the PowerSmart 21-Inch, is typically sufficient.
However, for larger properties (1/2 acre or more) or areas with significant slopes, you should upgrade to a 170cc or even a 200cc engine (like the YARDMAX 201cc). Greater power results in less strain on the engine and ensures a cleaner cut, even when dealing with thicker grass.
Self-Propel System: Speed and Control
While RWD is beneficial for traction, the type of self-propel system significantly impacts user comfort. Some mowers, like the PowerSmart single-speed models, offer a simpler system that is adequate for many users.
However, variable speed options, such as the Continuously Variable Transmission (CVT) found in the YARDMAX or the variable speed system in the SENIX, provide the most control.
Variable speed systems allow you to match the mower’s pace precisely to your walking speed, reducing fatigue, which is crucial for larger properties.
Deck Size & Material
The size of the deck determines the amount of grass cut with each pass. A 21-inch deck is standard for most residential lawns, but increasing to a 22-inch deck (as featured on most PowerSmart and YARDMAX models) will decrease mowing time on larger properties.
Deck material is also crucial for durability. Steel decks are the most durable and can withstand rough terrain, though they are heavier. For a balance of durability and manageable weight, look for features like a 16-gauge stamped steel deck.
Cutting Options & Height Adjustment
Most RWD mowers offer 3-in-1 functionality: mulching, side discharge, and rear bagging.
- Mulching returns finely chopped clippings to the lawn, acting as natural fertilizer.
- Rear bagging collects clippings for a pristine lawn appearance.
- Side discharge ejects clippings to the side.
A wider range of cutting heights, such as the 7 positions offered by the YARDMAX, allows you to adapt the mower to varying grass types and seasonal conditions.
Additional Features
Look for these added conveniences:
- Wheel Size: Larger rear wheels (e.g., 11 inches) generally improve traction.
- Washout Port/Deck Cleanout Port: These simplify the cleaning process by helping remove grass buildup under the deck.
- Foldable Handles: Essential for compact storage.
The Bottom Line
Ultimately, the best RWD lawn mower is one that aligns with your specific lawn size, terrain type, and preferred cutting style.
Investing in a quality RWD mower with features like a strong engine (170cc+ for slopes) and, ideally, a variable speed self-propel system will save you considerable time and effort in the long run.
By evaluating power, deck size, and specific features, you can find a machine that ensures a beautifully manicured lawn for years to come.
