High-grass, ride-on mower with permanent all-wheel drive
The AS 940 Sherpa 4WD is a robust, versatile ride-on mower for difficult terrain and high growth. The machine’s 2-cylinder Briggs & Stratton engine with 724 ccm displacement, up to 27 hp and an oil and fuel pump achieve work rates reaching 5,500 m² per hour. Permanent all-wheel drive delivers better traction uphill and stronger, safer braking downhill. The limited slip differential can be activated at any time for more safety. Hydrostatic transmission is controlled exclusively via the drive lever, which controls forward and reverse movements as well as the brake and the parking brake. An additional brake pedal returns the drive lever to neutral and automatically engages the parking brake.
Equipped with the AS cross-blade system, the AS 940 Sherpa 4WD delivers impressive mulching results in grass and dense growth up to 1.5 meters high. Bearing-supported blades cut the grass while a mulching blade positioned above them shreds the cuttings, which are then deposited between the wheels for added safety on slopes and wet grass. The mower deck’s surfing suspension yields upwards to obstacles, protecting the blades and turf from damage. Cutting heights can be adjusted to 5 levels from 50–105 cm and an option mulch kit is available for even finer mulching results.
Stability and comfort
With a highly stable tubular frame, the AS 940 Sherpa 4WD performs even under harsh conditions. Operators up to 1.9 tall can operate the machine comfortably thanks to a length-adjustable seat and seat spring package. A low centre of gravity, folding bar and branch deflectors are added safety features, while lashing points integrated in the frame enable secure transport.
The AS 940 Sherpa 4WD is engineered for continuous operation with two separate ventilation circuits for the engine and hydrostatic transmission. 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 prevents overheating and ensures the machine’s long service life.
The all-wheel drive ride-on mowers in a new design
The all-wheel drive models of the Sherpa family will appear in new splendor in the future. With a new paint finish, an additional front panel and the newly designed labels, the Sherpa’s will be even more attractive in the future. The re-design of the Sherpa family also offers some technical innovations.
In future, all all-wheel-drive Sherpa models will come with the liquide tyre sealant “AS-Motor Plattfuss-Stop” as standard – downtimes caused by flat tires will no longer be an issue. The Sherpas’ new fuel tank offers more volume (17 liters), a larger tank opening and a level indicator. The new locking mechanism of the folding safety bar ensures easier handling and makes the bar less prone to damage. There is also improved elbowroom when operating the driving lever. In the future, the protective cloth between the engine and seat will no longer be elaborately riveted, but locked in place using robust magnets. Accessibility to the engine, for example when adjusting the valves, is significantly improved
