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 29.3 cu in 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 (1.1 mph) that covers a speed range from 0.7–2.5 mph.  The rear axle differential is permanently locked, resulting in excellent traction even on wet grass.  Twin tires ensure even greater traction and stability while a vertically installed engine provides a low center of gravity and balanced distribution of weight, at a total of 502 lb.

 

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 36 inch 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 4 feet tall at work rates reaching 4,306 yd² 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 0.8–3.9 inches, while the operating bar can be conveniently adjusted laterally and in height to match both the operator and the conditions.
