The Masport professional Contractor range, featuring the 19" Contractor AL 3’n1 and the 21" Contractor ST 3’n1, offers an interesting choice for both domestic and professional users. Both models boast heavy-duty chassis, reinforced axles, and the advanced Masport Quadcut® four-blade cutting system, ensuring superior cutting, catching, mulching, and rear-discharge performance. Both are powered by a Briggs & Stratton 850 engine, and both machines offer reliable starting and powerful operation for demanding conditions. Additionally, comfortable upturned upper handles with soft grips enhance ergonomics and reduce fatigue during prolonged use. But there are a few differences which set up the two models to suit different situations.
