The robust ride-on flail mower AS 1040 YAK 4WD XL is made for the tough use in uneven, rough, steep and undulating terrain. The ride-on mower shreds extensive green areas, growth up to 1.50 metres, undergrowth and scrub effortlessly and reliably. This makes this flail mower suitable for professional use by service providers, local authorities and garden and landscaping contractors. Essential for the off-road capability is the low centre of gravity and the large XL tyres of the machine for even more ground clearance than the AS 1040 YAK 4WD.

The AS 1040 YAK 4 WD XL is powered by a professional Vanguard V-Twin engine. The horizontal engine delivers a maximum of 23 hp (17.2 kW) at 627ccm displacement and transmits the power via V-belts directly to the flail shaft. Optimum fresh air supply to the engine is ensured by the cyclone air filter. Thanks to the oil and fuel pump, the AS 1040 YAK 4WD XL is fully suitable for slopes.

Thanks to the hydrostatic drive, the ride-on flail mower can be steered comfortably and continuously in the range of 7.3 km/h forwards and 6.8 km/h backwards. The permanent four-wheel drive and XL ground clearance ensure the best possible propulsion on any terrain. The rear axle differential can be locked at any time by foot pedal. Driving is simple and comfortable using the hand control lever. The automatic parking brake and the cruise control function are also integrated in the drive lever. For safety reasons, the machine also has an emergency brake pedal for the right foot, just like a passenger car.

The mulch mowing deck with 56 Y flails and a working width of one metre creates area outputs of up to 7,300 m²/h. The cut material is deposited as a mulch layer evenly over the entire working width. The cutting pattern, even with very high vegetation, is visually homogeneous and attractive. 7 levels are available for adjusting the cutting height from 30-110 mm. The pendulum suspension of the mowing deck allows it to move upwards when sitting on the sides or when applying high force to the blades (surfing mowing deck). The asymmetrical arrangement of the mowing deck enables efficient mowing of edge areas and obstacles.

The ergonomic and upright sitting position in the machine ensures ample legroom for operators up to 1.95 m tall. The bucket seat is  adjusted in length to suit any user. The innovative suspension system with end position damping is also individually and continuously adjustable to suit every operator. In addition, all operating elements are logically arranged and conveniently accessible. Aluminium side panels protect the driver’s hands from thorns and undergrowth. A standard puncture protection with AS Motor „Plattfuss-Stop reliably prevents flat tires.

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.

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 differential on the rear axle can be blocked at any time via a foot pedal; a drive lever with integrated parking brake and cruise control ensures easy operation.

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.

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.

The robust ride-on flail mower AS 1020 YAK 2WD is made for tough use on flat terrain with slight inclines. The ride-on mower shreds extensive green areas, growth up to 1.50 metres, undergrowth and young scrub effortlessly and reliably.
