AS 65 4T B&S

Professional Allmäher powered by a Briggs & Stratton engine

Mulch where others hit their limits. Equipped with a Briggs & Stratton Series 3 INTEK engine with an oil and fuel pump, the AS 65 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. 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 3,300 m² per hour are possible due to a powerful Briggs & Stratton engine with up to 13.0 hp, traction drive and a 65 cm cutting width. The AS 65 4T B&S effortlessly cuts grass up to 150 cm high. Not least, the engine/blade reduction of 1:2 delivers outstanding cutting performance while the AS cross-blade cutting and shredding system achieves a fine mulching result. The AS 65 4T B&S is thus suitable for virtually every application, whether on slopes or in dense, high grass.

Convenient, safe and simple operation.

The AS 65 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 65 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. Drive wheels with field studs ensure optimal propulsion on both slopes and level ground.

Impressive results in high grass and undergrowth

A closed mowing deck with a cross-blade system and an overlying wing blade keep grass inside the deck so it is cut many times. This leads to uniform cutting results and a fine mulched material, along with a lower risk of ejected foreign objects. An oil pressure sensor alerts the operator to engine lubrication levels so as to best avoid engine damage.

Product advantages

Performs on slopes

Extra fuel and oil pump with oil pressure switch optimize performance on slopes.

Perfect mowing and mulching

The AS cross-blade system cuts and shreds grass simultaneously.

High cutting capacity (AS 65)

1:2 engine-blade reduction for high cutting capacity in dense growth.

Automatic parking brake

When the drive lever is released the machine stops automatically, whether on a slope or level ground.

Switchable limited slip differential

Permanently locked limited slip differential opens by pressing the differential lock lever.

Engine protection

Separate engine and blade shaft protects engine.

Simple operating concept

Operation of parking brake, blade engagement, limited slip differential, drive function, speed adaptation, all with just three levers.

Drive wheels

Inflatable tyres with field studs for excellent traction on slopes.

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.

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.

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.


AS-Motor offers professional technology for the maintenance of green spaces in and around public utility facilities.

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.

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.

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.

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.

Road maintenance

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


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.
