ATM Allmäher® AS920 Sherpa 2WD

The AS 920 Sherpa 2WD boasts work rates reaching 9,450 m² per hour, thanks to its 90 cm cutting width and a high-power Briggs & Stratton 2-cylinder engine with 724 ccm displacement and up to 27 hp. The closed, surfing mower deck gives way upward which protects both the blade and the turf, as the blade will not come into contact with the ground. Moreover, the shape of the mower deck allows flush, close-to-the-edge mowing. The AS 920 Sherpa 2WD has a turning radius of just 65 cm.

The AS 920 Sherpa 2WD’s cross-blade system 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. Cutting heights can be adjusted to 5 levels from 35–135 cm with an optional mulch kit available for even finer mulching results.

Hydrostatic transmission allows the precise adaptation of speed to match the terrain, reaching 10.5 km/h and 8.2 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 when needed.

With a highly stable tubular frame, the AS 920 Sherpa 2WD performs even under harsh conditions. Operators up to 1.9 m 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.

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.

In the future, the 2WD models of the Sherpa series will appear in new splendor. Visually, the new Sherpa models are even more attractive with a new paint finish, an additional front panel and the newly designed decals. But the legendary tallgrass mowers also offer a number of technical innovations.

In addition to more volume (17 liters), the Sherpas’ new fuel tank offers a larger tank opening and a level indicator as standard. The protective cloth between the engine and seat can now be easily opened for service activities using a magnetic catch. Accessibility to the engine, for example when changing the oil, is significantly improved. The locking mechanism of the folding handle has been redesigned and prevents elbow bumping.
