Detailed Description (from Product Description)
The PowerSmart 21" mower is engineered as a compact, low-maintenance option for residential lawns. The 140cc engine provides reliable torque to handle thick grass and uneven terrain while the wide cutting deck helps you finish faster. As a 3-in-1 mower with mulching, side discharge, and bagging, it adapts to different lawn conditions — cut and collect when leaves are falling, mulch clippings back into the turf during growing season, or discharge when grass is too heavy for the bag.
The mower’s 6-position height adjustment system is user-friendly: with a single lever you can change the deck height to get the desired finish. The steel deck construction adds durability for regular use, and the compact design makes it easy to maneuver around tight beds and walkways — ideal if you’re looking for a compact gas push mower for tight spaces and residential yards.
Maintenance is straightforward: a 4-stroke engine means no premixing of fuel and oil, and periodic oil changes and blade sharpening are all that’s required for long-term performance. Replacement blades and accessories — like the PowerSmart 21 inch mower replacement blades and accessories — are available, making upkeep simple.
