AS 1040 YAK 4WD

Strong, robust and at home on difficult terrain – AS 1040 Yak 4WD

AS-Motor’s new robust ride-on flail mower is engineered for uneven, rough and steep terrain. The AS 1040 Yak 4WD shreds grass up to 1.5 metres tall as well as brush and young saplings.  With high work rates and even more safety, the flail mower is an ideal tool for professional users such as commercial landscapers and municipal operators.

A powerhouse with direct flail shaft drive

The AS 1040 Yak 4WD is powered by a Briggs & Stratton 2 cylinder Vanguard V-Twin engine with up to 23 hp (17.2 kW) and 627 ccm displacement. The engine is horizontally placed and thus transfers the force directly to the flail shaft through a V-belt, while a cyclone air filter delivers fresh air supply. The engine’s oil and fuel pump guarantees performance on slopes.

Variable 4WD with cruise control function

Hydrostatic transmission allows the operator to conveniently control the AS 1040 Yak 4WD’s speed up to 6.8 km/h forward, and 6.3 km/h in reverse. Permanent 4WD delivers propulsion no matter the terrain.  The rear axle differential can be blocked at any time via a foot pedal; a drive lever with integrated parking brake and cruise control ensures easy operation.

Surfing flail mower unit with Y-flails

The AS 1040 Yak 4WD achieves work rates reaching 6,800 m²/h thanks to its 1-metre working width and 56 Y-flails that shred grass and deposit the mulch uniformly across the work area. Cutting height can be adjusted to 7 levels between 30-110 mm.  A surfing mower deck and Y-flails that give way protect the engine, and the operator, from damage in the event of unseen objects or uneven terrain.  The mower deck’s asymmetric shape allows efficient mowing close to fences and around objects.

Comfort for long work days

An ergonomic sitting position provides adequate legroom for users up to 200 cm (6’6″) tall, while the bucket seat and innovative suspension system with end position damping can be adapted to every operator.
