Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower

Powered by an 80V system, this cordless mower tackles hills with rear-wheel drive and variable speed control for traction. The 21″ steel deck hosts a brushless motor for efficiency and longer life. A 4.0Ah battery supports a broad mowing window, and LED headlights aid visibility in shaded or early-morning conditions.
YARDMAX 22 in. 201cc CVT Self-Propelled Mower

This gas mower features a Continuously Variable Transmission (CVT) for adjusting pace to your walking speed, with automatic choke for easy starting. Aggressive-tread rubber tires enhance traction on slopes, while a 6-speed range provides precise control over downhill and uphill mowing.
STEELITE 21V 13-Inch Brushless Cordless Mower

Ultra-lightweight at about 20.5 pounds with a compact 13″ deck, this mower is designed for small yards and slopes where agility matters. A 21V 4.0Ah battery provides steady runtime for smaller lawns, and a one-touch height adjustment ranges from 0.98″ to 2.56″.
AMRISUN 21-Inch Self-Propelled Gas Lawn Mower

Equipped with a 170cc 4-stroke engine, this mower delivers robust cutting performance for larger yards. Its high-wheel design aids maneuverability on hills, and it offers 3-in-1 mowing: mulch, side discharge, or rear bagging to suit varying lawn conditions.
PowerSmart 21″ 3-in-1 Push Lawn Mower

Buying Guide: Key Purchase Considerations For Hills
- Power source and torque: For hills, look for sufficient torque and traction. Gas models generally offer strong pulling power, while high-voltage cordless mowers provide consistent torque with no fuel handling.
- Traction and drive system: Rear-wheel drive with variable speeds helps maintain stability on slopes. Some models include CVT or automatic adjustments to pace the terrain.
- Deck size and weight: A larger deck covers more area but adds weight. Excessive weight can hinder maneuverability on steep inclines; balance deck size with ease of control.
- Height adjustment and mulching: Multiple cutting heights help tailor performance on hills and irregular turf. Mulching capability can reduce clumps on slopes.
- Maintenance and runtime: Battery capacity and runtime matter for larger hills. Gas engines require regular maintenance, but can handle extended mowing sessions.
- Storage and portability: Compact models or lighter designs simplify storage in garages or sheds and make transport to hilly properties easier.
When choosing, compare traction features, ease of starting on slopes, and how the mower handles uneven terrain. Consider yard size, slope gradient, and whether you prefer the quiet convenience of cordless models or the robust power of gas engines for steeper hills.
