AS-Motor 73 4T B&S Petrol Allmäher Mower

AS 73 4T B&S

Product details

Height adjustment

Central, variable height adjustment from 50–100 mm.

Manual transmission

5-speed manual transmission with limited slip differential and reverse gear provide optimal propulsion, even on a wet grass.

Closed mower deck with rear discharge

Grass and growth are finely cut and mulched in the closed mowing deck with rear discharge. This system also enables work close to edges.

Adjustable operating bar

Guide bar can be adjusted laterally and in height to adapt to the size of each operator.

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.

Operation is simple, convenient and safe

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.

Impressive cutting results thanks to a cross-blade system

The cross-blade system consists of a main blade and an overlying wing blade, providing four cutting edges to tackle grass and undergrowth. A closed mowing deck means the cut grass remains inside for longer, and is cut many times. Combined with a high blade speed, the AS 73 4T B&S offers excellent cutting results in low to medium-high grass.

Applications

Gardening and landscaping

AS-Motor’s professional technology offers solutions for the diverse tasks of gardening and landscaping, from outdoor facilities to private gardens, public parks and residential lawns.

Road maintenance

Maintaining roadways often involves mowing high grass and slopes, two specialties of AS-Motor’s professional technology.

Commercial landscaping

Performance on rough terrain, perfect cutting results and high efficiency are advantages AS-Motor machines provide to professional service providers.

Meadow orchards

Meadow orchards characterize the landscape of diverse regions and provide valuable ecosystems for insect and bird life. Maintaining these areas often involves mowing around trees, on slopes and in rough terrain.

Hunting and forestry

In forests and on hunting grounds, mowing can take place as infrequently as once per year or even at intervals of several years. AS-Motor machines are engineered to tackle the thick growth native to these areas as well as Christmas tree plantations.

Viticulture

Viticulture, or wine-growing, is one of civilization’s oldest forms of agriculture. AS-Motor was founded 60 years ago with the objective of tackling the slopes and thick growth of vineyards.

Leisure facilities

Leisure facilities must be visually appealing and expertly maintained. Whether parks or campsites, these areas are frequently used and thus require careful maintenance.

Municipal maintenance

Caring for green areas in the civic environment involves a variety of tasks. From parks to roadside management, AS-Motor provides the correct tools to ensure both professional results and operator safety.

Solar parks

Efficiency is crucial to maintaining a profitable solar park. AS-Motor offers the ideal tools to properly maintain the green areas around and under solar panels.

Athletic facilities and golf courses

Management of edge areas, embankments and lawns of athletic facilities are as important as the greens themselves.
