AS 901 SM
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.
Extra fuel and oil pump with oil pressure switch optimize performance on slopes.
Pendulum-bearing supported flail mower unit with 26 pairs of Y-flails for high work rates and an extremely clean mulching result.
When the drive lever is released the machine stops automatically, whether on a slope or level ground.
Single-wheel brake controls the device precisely and effortlessly.
Permanently locked limited slip differential opens only when steering with the steering and brake clutch.
Stable, lightweight construction with double-wall mower deck and rigid square frame. Low centre of gravity for optimal slope performance.

With the AS 901 flail mower I mow the grass and vine prunings between rows at the same time. This means less work cutting and no need for herbicides.
AS 901 is our constant companion in the training area. The powerhouse has to deal with 2-metre high reeds, bushes and grass. It unconditionally creates free space for the birds and insects. It is agile, powerful and is equipped to deal with all challenges.
We use the AS 901 SM especially on slopes, but also on straight, narrow areas. The good mowing pattern is still present even in long and dense grass. The purchase of this machine has considerably improved the safety of our staff. Another major advantage is that it makes the work easier for the staff and thus more efficient.
The AS 28/4 Enduro and the AS 65 Scout, which I bought second-hand, are the machines that proved their quality and gave me the confidence to go and buy my first new machine, the AS 901 SM. The power and manoeuvrability of the AS 901 SM is something that makes me approach every job with a smile. These three AS-Motor machines got me even to the point, where I want to start my own landscaping business.
My first info about the brand was via internet. After demonstration I decided to buy AS 901 SM - I was impressed with the performance of the machine, it is perfect for my orchard. A year after that, I became the owner of one more AS machine - AS 531 2T ES MK B for my backyard – that the best review, I think.
