PowerSmart Self Propelled Gas Lawn Mower 21-Inch

PowerSmart combines a rear-wheel-drive system with a robust 170cc OHV 4-Cycle engine. The single-speed forward propulsion (approx. 3.5–4.1 km/h) delivers steady momentum on slopes and uneven terrain, reducing user strain during mowing sessions. The 21-inch steel deck provides durability, while the included mulching blade helps return nutrients to the lawn. This mower supports 3-in-1 operation, allowing bagging, mulching, or side discharge with ease, making it versatile for different grass conditions and seasonal needs.
PowerSmart 21-Inch 3-in-1 Gas Self-Propelled Lawn Mower

This model is powered by a reliable 170cc OHV engine and features a wide 21-inch cutting width for efficient coverage. Its 3-in-1 design supports bagging, mulching, and rear-discharge, allowing you to switch between modes to maintain lawn health and appearance. The steel deck contributes to overall durability, and the rear-wheel drive assists traction for tackling varied terrains, including hills and thick patches.
WORX Nitro 21″ Cordless Lawn Mower

The WORX Nitro relies on a brushless motor delivering more power and longer runtime, paired with two 20V 5.0Ah PowerShare Pro batteries and a cordless design for quiet, low-maintenance mowing. Aerodeck technology improves airflow, reduces clogs, and enhances cutting performance. The mower is self-propelled with adjustable speed, letting you set a comfortable pace up to about 3.7 mph, while the deck layout supports efficient bagging and mulching.
YARDMAX 22 in. 201cc Select PACE 6 Speed

The YARDMAX YG2860 uses a CVT-driven 6-speed system to match your walking pace, enhancing control on slopes and flat terrain alike. Its 22-inch cutting width covers more ground per pass, while a 3-in-1 design supports bagging, mulching, and rear discharge. The mower includes automatic choke for easier starts and a robust overall build designed for frequent yard maintenance across different grass types.
Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower

Greenworks offers a full electric option with an 80V brushless motor and a carbon-efficient lithium-ion battery setup. The 21-inch deck supports a respectable mowing width, and the 4.0Ah battery provides solid runtime for mid-sized lawns. Rear-wheel drive with a variable speed control ensures solid traction in varied conditions, and LED lights on some models improve visibility for early morning or dusk mowing sessions. The kit typically includes a battery and rapid charger for quick turnover between tasks.
Buying Guide: Key Considerations For Selecting A Self Propelled Mower
- Power source and maintenance: Gas mowers deliver strong sustained power suitable for thick or tall grass, but require more maintenance and routine fuel management. Cordless electric mowers offer low noise, zero emissions, and simpler maintenance but depend on battery life and charging time. Evaluate your yard size and preferred maintenance level to choose between gas and electric.
- Propulsion and traction: Rear-wheel drive provides better traction on slopes and uneven ground, while front-drive models can be lighter and easier to maneuver. Some units offer variable-speed self-propulsion, letting you tailor pace to your walking speed and terrain.
- Deck size and material: A 21-inch deck is common for residential yards and balances weight with mowing width. Steel decks are durable and forgiving on rocky patches, while aluminum decks are lighter but may cost more.
- Cutting options: Look for 3-in-1 capabilities (bagging, mulching, discharge) to adapt to lawn health and weather. Height adjustability (common 6- to 7-position ranges) helps tailor the cut to grass type and season.
- Maintenance and durability: Easy-start engines, automatic chokes, and well-engineered transmissions improve reliability. Consider warranty coverage and ease of blade replacement when selecting a model for long-term use.
- Noise and emissions: Electric mowers typically operate with lower noise levels and zero direct emissions, making them suitable for noise-restricted neighborhoods. Gas mowers produce more noise and require fuel management but may be preferable for larger or tougher lawns.
- Battery ecosystem (for cordless models): If choosing a battery-powered mower, consider compatibility with other tools in the same brand’s ecosystem to maximize value and reduce extra purchases.
- Weight and ergonomics: A lighter mower reduces user fatigue, while adjustable handles and comfortable grip improve operation over long mowing sessions.
- Runtime and capacity: For cordless models, ensure the battery capacity matches your yard size. For gas models, check fuel efficiency and tank capacity to plan refueling intervals during mowing.
These considerations help compare models across propulsion type, cutting technology, and user experience. Always align your choice with lawn size, terrain, preferred maintenance level, and environmental preferences to achieve best results.
