PowerSmart 21" 170cc OHV Self-Propelled Gas Lawn Mower | 3-in-1, 60L Bag, 10" Rear Wheels

170cc OHV Engine, 10" Rear Wheels, 3-in-1 System — Built for Serious Yards

The PowerSmart V8721S is a 21" self-propelled gas lawn mower powered by a 170cc OHV 4-stroke engine with forced air cooling for reliable, consistent performance in all conditions. Large 10" rear wheels — the biggest in the PowerSmart lineup — roll over uneven terrain and slopes with ease. The 3-in-1 mowing system and 60L grass bag round out a mower built for medium to large residential yards.

• 170cc OHV 4-Stroke Engine with Forced Air Cooling — Overhead valve design runs cooler and more efficiently than standard engines. Forced air cooling extends engine life and maintains consistent power output in hot conditions.
• 10" Rear Wheels — The largest rear wheels in the PowerSmart lineup. Roll smoothly over slopes, uneven terrain, and obstacles that stop smaller-wheeled mowers in their tracks.
• Self-Propelled Drive — The mower moves itself forward, reducing fatigue on large yards and sloped terrain. You steer — it does the walking.
• 3-in-1 Mowing System — Switch between mulching (returns nutrients to your lawn), rear discharge, and bagging for complete flexibility across all lawn conditions.
• 60L Grass Bag — Large-capacity rear bag means fewer stops to empty on medium to large yards. More mowing, less interruption.
• 21" Cutting Width — Wide cutting path covers more ground per pass, reducing total mow time on mid-to-large residential lawns.
• 6-Position Cutting Height — 1.5" to 3.9" range lets you dial in the right cut for different grass types, seasons, and lawn conditions.
