The only meadow mower with two blade speeds
The Allmäher for professional use in challenging conditions. Equipped with a Briggs & Stratton Series 3 INTEK engine with an oil and fuel pump, the AS 73 4T B&S masters inclines up to 35 degrees without running the risk of engine damage. A separate engine and blade shaft protect the engine in case of unseen obstacles and propulsion occurs via a 5-speed manual transmission with reverse gear (2.4 km/h) that covers a speed range from 1.6–5.1 km/h. Work rates reaching 3,700 m² per hour are possible due to a powerful engine with up to 13.0 hp, traction drive and a 73 cm cutting width. The AS 73 4T B&S effortlessly cuts grass up to 150 cm high. Variable blade speed offers two options depending on the conditions: the fast blade speed achieves an even finer mulching result, while the slower blade speed’s increased torque is recommended for dense and high growth such as areas that are seldom mowed. The AS 73 4T B&S is thus suitable for virtually every application.
The AS 73 4T B&S works with operating levers that activate the parking brake, the traction drive, the limited slip differential and the blade clutch. Absolute safety for slope mowing is achieved by an automatic parking brake and limited slip differential which remains permanently locked while the machine is in drive. When the drive lever is released, the parking brake automatically engages and the AS 73 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. Cutting height can be adjusted from 50–100 mm while low-pressure tyres with field studs ensure optimal propulsion on both slopes and level ground.
- Performs on slopes Extra fuel and oil pump with oil pressure switch optimize performance on slopes.
