Kurt Jewson – The dream machine
"It’s rugged simplicity, comfort and sheer ability is always impressive. I come back from the woods, job done, all good and literally no sweat."
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.
With a highly stable tubular frame, the AS 940 Sherpa 4WD 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.
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.
Permanent all-wheel drive ensures better traction uphill and stronger, safer braking downhill.
Closed mower deck with AS cross-blade system. The main blade cuts, the cross-blade chops the cuttings. The surfing mower deck gives way upward on uneven terrain to protect against damage.
Length-adjustable driver seat, innovative seat suspension and ergonomic sitting position provide comfort for tall operators during long work periods.
High stability and torsional rigidity with heavy load.
Field stud tyres, switchable limited slip differential and an engine suitable for slopes ensure powerful traction on difficult terrain.
Easy adaptation of the speed to every terrain with integrated, mechanical parking brake in the drive lever.
Greater operator safety in the machine's limit area.

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.

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.

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!

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 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.

We use two AS 940 Sherpa for the green space maintenance of the open-air photovoltaic systems. Twice a year, we currently mulch around 200 hectares in this business area. The primary goal is to keep the solar modules free of shade. We mow under the solar tables, which means there is only about 90 centimetres of space between the turf and the tables in some places. Of course, the compact design and the low centre of gravity are very beneficial. In addition, the Sherpas with their all-wheel drive are very suitable for off-road use. Even if there is brushwood or high grass to be mulched, that is no problem, the Sherpas will stop nothing. With the AS mowers, we can get through anywhere.
