The Masport 21" Self Propelled professional mower features a commercial grade 3 speed transmission and is powered by a commercial Briggs & Stratton 850 engine. This mower is designed for large yards, small acreage and commercial use. The heavy duty high arch steel chassis is able to withstand sandblasting and hard impacts and is combined with the Quadcut 4 blade cutting system resulting in superior cutting, mulching and catching performance. The heavy duty cast alloy wheels are extremely tough and are designed to operate under commercial conditions limiting possible down time.
