AS 940 Sherpa 4WD RC

The world’s first ride-on mower with remote control offers even more safety and convenience in difficult terrain

The world’s first ride-on mower with remote control, the AS 940 Sherpa 4WD RC can be operated comfortably both from the driver seat and via a professional remote control unit with a range of 300 yards.  Equipped with a professional Briggs & Stratton Series 8 engine and hydrostatic transmission, the AS 940 Sherpa 4WD RC can handle inclines up to 21 degrees in ride-on mode and slopes reaching 33 degrees when operated remotely.  Remote operation is ideal not only for slopes, but also hazardous situations such as under trees, along hedges, in the vicinity of stinging nettle or wasp nests or simply to avoid exposure to dust, noise or exhaust fumes.



Fatigue-free work in ride-on mode

With a highly stable tubular frame, the AS 940 Sherpa 4WD RC performs even under harsh conditions.  Operators up to 6 feet tall can operate the machine comfortably thanks to a length-adjustable seat and seat spring package.  A low center of gravity, folding safety bar and branch deflectors are added safety features, while lashing points integrated in the frame enable secure transport.



Closed surfing mower deck

Like the other Sherpa models, the AS 940 Sherpa 4WD RC’s cross-blade system delivers impressive mulching results in grass and dense growth.  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 3.1–5.3 inches via the remote control, whether in ride-on mode or operating from a distance.

Expert opinion: “Mowing on slopes or roadsides involve risks. Vibration and exhaust are detrimental to health and given new alternatives, it may possibly no longer be an acceptable risk to allow public works employees to operate traditional mowers in these circumstances” (Hendrik Rößmann, technical instructor at DEULA Westfalen-Lippe GmbH, KommunalTechnik, Issue 1, Jan / Feb 2018)
