Mowing and mulching in one step. Equipped with a cross-blade system and powered by a Briggs & Stratton engine with up to 5.5 hp; the AS 63 4T B&S easily cuts and shreds even high growth. A separate engine and blade shaft protect the engine in case of unseen obstacles. Variable drive enables speeds of 2.0–4.0 km/h. Work rates reaching 2,300 m² per hour are possible due to a high-performance Briggs & Stratton engine, variable drive and a 61 cm cutting width. The AS 63 4T easily cuts grass up to 90 cm high. The drive-reduction transmission with a gear ratio of 1:13.44 allows the AS 63 4T to brake autonomously when moving downhill. The machine will not speed up when moving downhill, no matter how steep the incline. The AS 63 4T B&S has a permanently locked limited slip differential while in drive; which increases traction and safety on slopes.

The AS 63 4T B&S works with operating levers that activate the parking brake, the traction drive, the limited slip differential and the blade clutch. The automatic parking brake is an additional safety aspect. When the drive lever is released, the parking brake automatically engages and the AS 63 4T B&S stops, whether on a slope or level ground. For convenient operation the guide bar is equipped with a V-handlebar; which can be adjusted laterally and for height without tools. “VibrationProtect” vibration damping reduces hand-arm vibration to a minimum.
