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.

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.

  • Flail over rotary?: Stable and robust asymmetrically arranged surfing flail mower unit.
  • Uniform grass placement: Perfect mowing results over the entire working width.
  • Made for professionals: Flail rotor drive and diminished need for path overlap guarantee high work rates.
  • Robust and durable: Stable, square-tube frame with weight-optimized design, low-maintenance hydrostatic transmission and optimal cooling.
  • Extremely suitable for slopes: Low centre of gravity and 4WD guarantee safety on slopes.
  • Stable lateral position: Balanced weight distribution – 45% on the front axle and 55% on the rear – ensures outstanding traction and safe work on every terrain.
  • Safety first: Maximum operator safety thanks to stable folding bar, integrated safety switch in the driver seat, and emergency stop foot pedal.
