AS 940 Sherpa 4WD B&S
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 AS-Motor all-wheel drive ride-on mowers in a new design
The all-wheel drive models of the AS-Motor Sherpa family will appear in a new design in the future. Visually, the new 2023 Sherpa 4WD models are even more attractive with a new paint finish, an additional front panel and the newly designed decals. But the new AS Sherpa 4WD high grass mowers also offer a number of technical innovations.
All all-wheel drive AS Motor Sherpa 2023 models will in future be fitted with anti-puncture tyre sealant as standard – downtimes due to flat tyres are now a thing of the past. The new fuel tank of the Sherpas offers more volume (17 litres), a larger tank opening and a level indicator as standard. The new locking mechanism of the foldable bar provides easier handling and makes the bar less susceptible to damage. There is also improved freedom of movement when operating the driving lever. In future, the protective cloth between the engine and the seat will no longer be elaborately riveted, but locked by robust magnets. Accessibility to the engine, for example when changing the oil, is significantly improved.
Permanent all-wheel drive ensures better traction uphill and stronger, safer braking downhill.

Mow stresssless with AS!
The machine’s low centre of gravity gives you a safe feeling, even on very uneven terrain. I am quite tall and still sit very comfortably with enough space – this never happens with ride-on mowers.
Dear AS-Motor Team, enclosed are a few impressions from today's green maintenance work on wind turbines. We are surprised every day anew by the performance of our Sherpa. With such a great machine, nothing can go wrong!
We use AS 940 Sherpa Adventure as well as AS 63 2-stroke including double tyres for the maintenance of wind farms. With the machines we achieve an excellent mulching result, regardless of whether it's lush tall grass or scrub. The slope capability of both machines is impressive and convinced us completely during the demonstration that was offered to us before the purchase. Before buying the AS machines, we worked these areas with brushcutters. By using the AS 63 and AS 940 Sherpa, the area performance has improved significantly and the workload reduction is brilliant.
MSC Gaildorf owns a 940 Sherpa and an AS 26 2-stroke 3-wheel mower for the maintenance of the motocross sports facility. The track goes up and down - with various steep slopes. For high area output on slopes, the Sherpa is just perfect - while the AS 26 2T excels on extreme slopes of the jump hills. These two machines also form the basis for our international events. We are happy to use rental equipment from AS-Motor for our large events in order to prepare the entire event area optimally within a very short time. We have had very positive experiences with the high-end machines 1040 YAK and 940 Sherpa RC from AS-Motor. Real professional machines for the most difficult areas and conditions.
We have been working with AS machines for over 25 years. Most recently, the AS 940 Sherpa convinced us so much that we had already ordered the second machine. We also use the Sherpa for winter maintenance or as a 'small' tractor in places where our other machines cannot reach. Furthermore, the size of the machine is optimal so it can be transported without any problems - even in a van. At a landfill site, we used the AS 940 to transport plants because Sherpa was the only machine the client had no conserns about its weight.
Structural change does not stop at the cultivation of our orchard meadows. In order to make it attractive for future generations, we decided to buy a Sherpa. We tested the core competitors in comparison, deciding on an AS 940 Sherpa 4WD due to its handling, equipment and off-road capability as a 4WD model. The limited special model Adventure leaves nothing to be desired.
Dr. Michael Köbler (Geschäftsführer, Hofgut Serrig, Nähe Trier)Since the farm is entirely self-supporting, the economic efficiency and thus the maintenance costs and the useful life of a new acquisition are also decisive. "I was very pleasantly surprised by the consumption in particular," says Dr Köbler and adds with a smile: "With the previous model, you had the feeling that you had to drive right behind with the tanker. I couldn't imagine that the mower from AS-Motor would be so economical." In fact, AS-Motor's Sherpa stands out for its low consumption of a maximum of 4.7 litres per hour in extremely tall grass.
Performance on rough terrain, perfect cutting results and high efficiency are advantages AS-Motor machines provide to professional service providers.
Gardening and landscaping
AS-Motor’s professional technology offers solutions for the diverse tasks of gardening and landscaping, from outdoor facilities to private gardens, public parks and residential lawns.
Meadow orchards characterize the landscape of diverse regions and provide valuable ecosystems for insect and bird life. Maintaining these areas often involves mowing around trees, on slopes and in rough terrain.
Caring for green areas in the civic environment involves a variety of tasks. From parks to roadside management, AS-Motor provides the correct tools to ensure both professional results and operator safety.
Viticulture, or wine-growing, is one of civilization's oldest forms of agriculture. AS-Motor was founded 60 years ago with the objective of tackling the slopes and thick growth of vineyards.
Athletic facilities and golf courses
Management of edge areas, embankments and lawns of athletic facilities are as important as the greens themselves.
Equestrian areas require various forms of green care. Whether maintaining paddocks or lawns, AS-Motor offers tools to create the ideal equestrian environment.
Hunting and forestry
In forests and on hunting grounds, mowing can take place as infrequently as once per year or even at intervals of several years. AS-Motor machines are engineered to tackle the thick growth native to these areas as well as Christmas tree plantations.
Leisure facilities must be visually appealing and expertly maintained. Whether parks or campsites, these areas are frequently used and thus require careful maintenance.
Maintaining roadways often involves mowing high grass and slopes, two specialties of AS-Motor’s professional technology.
Efficiency is crucial to maintaining a profitable solar park. AS-Motor offers the ideal tools to properly maintain the green areas around and under solar panels.
