AS 701 SM

Flail mulcher for slopes and difficult terrain

High work rate and perfect handling. Equipped with a Briggs & Stratton Series 3 engine with an oil and fuel pump, 344 ccm displacement and up to 13 hp, the AS 701 SM performs in high grass, dense growth and on slopes without the risk of engine damage. Propulsion occurs via a 5-speed transmission with reverse gear (1.7 km/h) that covers a speed range from 1.1–3.6 km/h. A permanently locked rear axle differential provides increased traction and better handling on slopes. At just 196 kg, the AS 701 SM has a vertically-positioned engine resulting in a low centre of gravity and balanced distribution of weight.

Expert engineering with added safety

The AS 701 SM is controlled via 4 operating levers. The patented steering and brake clutch system allows control of each wheel via an operating lever. Light pressure on the lever opens the limited slip differential, while full pressure activates the brake on that wheel. Furthermore, the limited slip differential is permanently locked when in drive. The automatic parking brake engages as soon as the drive lever is released, stopping the flail mower whether on a slope or level ground: an added safety feature. Teflon-coated stainless steel Bowden cables ensure minimal expenditure of force. The result is safe, simple, and convenient operation.

Performance in challenging conditions

The AS 701 SM’s mulching deck has 20 pairs of Y-flails and a 70 cm cutting width, achieving work rates up to 2,500 m² per hour. Supported by pendulum bearings, the flail mowing unit compensates for uneven ground and thus delivers uniform mulching results in grass up to 100 cm high as well as dense undergrowth. The flails ride up and over obstacles, protecting both the engine and the operator from damage. A perforated impact guard provides additional safety.

Cutting height can be adjusted to 6 levels from 10–100 mm, while the operating bar can be conveniently adjusted laterally and in height to match both the operator and the conditions.

Commercial landscaping

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

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.

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.

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.

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.

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.


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


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.
