About the AS MOTOR AS 1040 Yak 4WD Ride-On Flail Mower
Professional Flail Mowing For Extreme Terrain
The AS-Motor AS 1040 Yak 4WD Ride-On Flail Mower is engineered for demanding professional mowing across rough landscapes. Designed for contractors, municipalities, and commercial land managers, it delivers exceptional performance in difficult working conditions. Powered by a 627cc Briggs & Stratton Vanguard V-Twin engine, it produces up to 23hp for outstanding cutting performance. Its robust construction confidently handles steep slopes, dense vegetation, and challenging terrain.
Capable of shredding grass up to 1.5 metres high, the AS 1040 Yak 4WD tackles demanding vegetation effortlessly. Its wide one-metre working width also delivers impressive productivity across larger areas with fewer passes.
Exceptional Cutting Performance With Flail Technology
The advanced surfing flail mower deck features 56 heavy-duty Y-flails that finely shred vegetation before distributing mulch evenly. This produces a tidy finish while naturally returning nutrients across the ground. The flails also lift over obstacles, helping protect both the mower and operator from unexpected impacts.
The innovative surfing suspension allows the mower deck to move independently across uneven terrain. This reduces scalping while maintaining consistent cutting quality across rough landscapes. An asymmetrical deck design also improves access when mowing alongside fences, walls, and other obstacles.
Powerful Four-Wheel Drive Performance
The Briggs & Stratton Vanguard V-Twin engine transfers power directly to the flail shaft using a durable belt drive. A cyclone air filtration system supplies clean air while helping maximise engine reliability. Integrated fuel and oil pumps maintain dependable performance when operating on steep slopes.
The hydrostatic transmission provides smooth speed adjustment up to 6.8km/h forward and 6.3km/h in reverse. Permanent four-wheel drive delivers excellent traction across wet grass, loose ground, and uneven terrain. A foot-operated rear differential lock further improves grip whenever additional traction becomes necessary.
Outstanding Comfort Throughout Long Working Days
The spacious operator platform provides generous legroom for users up to two metres tall. An ergonomic bucket seat with advanced suspension helps reduce fatigue during extended mowing sessions. Carefully positioned controls ensure every important function remains comfortably within easy reach.
A practical drive lever combines forward travel, reverse, parking brake, and stopping functions into one intuitive control. Integrated cruise control allows comfortable operation across larger working areas while reducing operator effort. Lateral deflectors also help shield the operator from heavy vegetation and thorny growth.
Built For Professional Reliability
The durable square-tube steel frame provides outstanding strength while maintaining excellent weight distribution for improved stability. Balanced axle loading helps maximise traction while improving safety across sloping terrain. A stable folding safety bar, emergency stop pedal, and seat safety switch further enhance operator protection.
Convenient service openings provide quick access for replacing flails, drive belts, and performing routine maintenance. Combining powerful engine performance, professional flail technology, permanent 4WD traction, and exceptional operator comfort, the AS-Motor AS 1040 Yak 4WD Ride-On Flail Mower is the ideal solution for maintaining demanding landscapes with confidence.
