Masport Contractor AL S19 3'n1
The Masport Contractor AL S19 3'n1 is the machine Masport builds for people who mow for a living. Reinforced axles, a commercial-duty aluminium chassis and the Quadcut four-blade disc put it a full class above a homeowner push mower, and it is the natural step-up sale from the President 1500.
Power is a Briggs & Stratton Series 850 Professional I/C, 190cc OHV - the professional-grade block with the heavier air cleaner and the longer service interval. The 485 mm (19 in) deck cuts from 10 mm to 73 mm and catches into a 67 L fabric catcher with a cover, so a full catcher still empties cleanly.
Why dealers stock it
- Quadcut four-blade disc - finer clippings, better catcher fill, and blades are a consumable the dealer resells.
- Reinforced axles built for trailer-to-site-to-trailer handling every day.
- Professional I/C engine: longer service interval, heavier air cleaner.
- 67 L fabric catcher - fewer stops per property.
