AS-Motor 901 SM Petrol Flail Mower

AS 901 SM

Product details

Height adjustment

Easy cutting height adjustment with lever.

Manual transmission

5-gear manual transmission with limited slip differential and reverse gear for excellent propulsion, even on wet grass.

Adjustable operating bar

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

Impact guard

A perforated impact guard ensures a high level of operator safety.

Professional flail mulcher with a high work rate

The AS 901 SM delivers high work rates and perfect handling whether on slopes, in dense growth or high grass. A Briggs & Stratton Vanguard Series 2-cylinder engine with 480 ccm displacement, up to 16.0 hp and an oil and fuel pump performs in tough conditions without the risk of engine damage. Propulsion occurs via a 5-speed manual transmission with reverse gear (1.8 km/h) that covers a speed range from 1.2–4.0 km/h. The rear axle differential is permanently locked, resulting in excellent traction even on wet grass. Twin tyres ensure even greater traction and stability while a vertically installed engine provides a low centre of gravity and balanced distribution of weight, at a total of 215 kg.

Operation is simple, convenient and safe

The AS 901 SM is conveniently operated via four levers. Individual wheels are controlled via a patented steering and brake clutch system by which light pressure on the wheel’s respective operating lever opens the limited slip differential; full pressure activates the brake on that wheel. Furthermore, the limited slip differential is permanently locked when in drive and the automatic parking brake engages as soon as the drive lever is released. This added safety feature stops the flail mower whether on a slope or level ground. Teflon-coated stainless steel Bowden cables ensure minimal expenditure of force. The result is safe, simple, and convenient operation.

Robust flail mowing unit

With a robust 90 cm wide flail mowing unit equipped with 26 pairs of Y-flails, the AS 901 SM is engineered for harsh conditions. The flail mower can cut grass up to 130 cm high at work rates reaching 3,600 m² per hour. The flail mowing unit is supported by pendulum bearings, delivering uniform mulching results by compensating for uneven terrain. 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.

Applications

Road maintenance

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

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.

Commercial landscaping

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

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.

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.

Utilities

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

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.

Accessories

Steel hand guard set

Additional protection for the operator.

Steel wheels, climbing aid

Improved traction, particularly when mowing diagonal to slopes.
