Handy High Grass Mower with impressive price/performance ratio
With its classic 3-wheel concept, the AS 21 4T B&S is AS-Motor’s entry level Allmäher. Equipped with a Briggs & Stratton 4-stroke engine with up to 5.5 hp, this Mower is suitable for grass up to 60 cm high. A third crankshaft bearing and friction discs on the wing blade protect the engine in the event of unseen obstacles. Large wheels with aggressive tread offer ideal propulsion at speeds up to 3.0 km/h.
Agile maneuvering thanks to the 3-wheel concept
The AS 21 4T B&S easily masters mowing on angles and curves. The swivel front wheel can be mechanically stopped diagonal to the slope while mowing, ensuring stability and comfortable work.
Work rates reaching 1,500 m² per hour are possible due to a powerful Briggs & Stratton engine, traction drive and a 51 cm cutting width. Cutting heights can be easily adjusted in two stages within the range of 55–80 mm on the front wheel while a low overall weight of 42 kg and a removable guide bar mean the AS 21 4T B&S can be reduced in size to compact dimensions and easily transported.
