The AS 940 Sherpa 4WD XL enables comfortable and safe mowing on slopes thanks to its Briggs & Stratton 2-cylinder engine with 724 ccm, 27 hp, and oil and fuel pump. Its permanent all-wheel drive, XL tyres with field stud tread, low centre of gravity and low total weight of only 298 kg provide stability on slopes. Hydrostatic transmission allows the precise adaptation of speed to match the terrain, reaching 6.7 km/h and 6.5 km/h in reverse. Just one lever controls the drive, brake and parking functions for easy operation, while limited slip differential can be activated for excellent propulsion and traction in extreme situations. A brake pedal returns the drive lever to neutral and automatically engages the parking brake.

The AS 940 Sherpa 4WD XL’s surfing mower deck is equipped with AS cross-blade technology in which bearing-supported blades cut the grass; while a mulching blade positioned above them shreds the cuttings. The mulched grass is then deposited between the wheels for added safety on slopes and wet grass; while the mower deck’s surfing suspension yields upwards to obstacles, protecting the blades and turf from damage. With a 90 cm cutting width, the AS Sherpa 940 4WD XL achieves work rates reaching 5,500 m² per hour. Cutting heights can be adjusted to 5 levels from 80–135 cm and an optional mulch kit is available for even finer mulching results.

The AS 940 Sherpa 4WD XL performs even under harsh conditions thanks to its highly stable tubular frame. A length-adjustable seat and seat spring package mean operators up to 2 meters tall can operate the machine comfortably; while a low centre of gravity, folding bar and branch deflectors are added safety features. Integrated lashing points enable secure transport.

Two separate ventilation circuits for the engine and hydrostatic transmission prevent overheating; the engine takes in air from above and discharges it to the side; while the hydrostatic transmission takes air from the rear and discharges it downward. This system ensures a long service life.
