AS-Motor High-Grass Mowers for Steep Slopes & Difficult Terrain
Made for high grass. Engineered for steep slopes.
Since 1959, AS-Motor has developed specialised mowing technology in Bühlertann, Germany, for terrain that pushes conventional machines past their limits. The first Allmäher® was created for high grass on steep vineyards & rarely cut orchard meadows.
That origin still shapes the machines today. The terrain determines the design: how the mower holds its line, processes dense growth & gives the operator control when the ground becomes difficult.
Repairable construction, long-term service support & spare parts stocked for more than 30 years help keep AS-Motor machines working beyond their first service cycle.
Find the AS-Motor mower for the job
Choose by vegetation, terrain & working method
Start with the conditions on the ground. How dense is the growth? Is the surface level, uneven or steep? Can the operator work directly on the machine, or is remote control the safer approach?
The product categories below provide different answers, from hand-guided mowers for high grass to ride-on machines, flail mowers & remote-controlled solutions.
Ariens, the Sister Brand of AS-Motor
Zero-Turn mowers & snow blowers for lawn and winter work
AS-Motor and Ariens are part of the AriensCo family. While AS-Motor specialises in high grass and steep slope mowing, Ariens develops Zero-Turn mowers for efficient lawn care and snow blowers for reliable winter maintenance. Together, the two brands cover a wide range of outdoor power equipment applications.
Applications
Where does the machine need to work?
A rarely cut orchard meadow creates different demands from a roadside embankment or solar park. Vegetation, access, slope & mowing frequency all influence which machine category fits.
Choose the application closest to your working conditions. Each section explains the challenges involved and points towards the AS-Motor solutions developed for that type of work.
-
Steep Slopes & Extreme Terrain: Low centre of gravity, 4WD & RC models guarantee traction & operator safety on gradients up to 56°.

Frequently Asked Questions About High-Grass Mowers
Choosing the Right Mower for Long Grass, Rough Terrain & Steep Slopes
The right mower depends on the vegetation, ground conditions, slope, access & size of the area. These answers explain where high-grass mowers, flail mowers, ride-on machines & remote-controlled solutions differ.
For long grass, dense growth or ground that is cut only occasionally, choose a machine designed for high-grass mowing rather than a conventional lawn mower. A hand-guided Allmäher® may suit smaller or less accessible areas, while ride-on mowers reduce working time across larger sites. Dense vegetation or unfamiliar ground may call for a flail mower.
A flail mower uses individually moving flails to cut and mulch high grass, scrub & dense growth. If a flail meets an unseen object, it can move backwards rather than taking the full impact through a fixed blade. This makes flail mowers particularly useful on large areas where the ground or vegetation is difficult to assess beforehand.
A rotary high-grass mower cuts with a horizontal blade system and suits many meadows, orchards & overgrown areas. A flail mower processes the vegetation with multiple moving flails, making it better suited to dense growth, scrub or ground where hidden objects may be present. The better choice depends on the vegetation, terrain & required finish.
Start with the permitted slope rating, traction, centre of gravity & operating method of the individual machine. Hand-guided and ride-on mowers suit different degrees of slope, while remote-controlled models allow the operator to work away from the immediate mowing area. Ground conditions, moisture & uneven surfaces must also be considered. The operating manual always takes priority.
Remote control becomes relevant when riding or walking directly with the machine would place the operator too close to a steep slope, roadside, embankment or another hazardous area. The operator can choose a position with better visibility and more distance from the machine. A ride-on mower remains useful where the terrain permits direct operation and larger areas need to be covered.
A mulching mower cuts the vegetation repeatedly inside the mowing deck before returning the material to the ground. On regularly maintained lawns, this removes the need to collect clippings. It does not automatically make the machine suitable for tall or dense growth. High grass requires a mower whose deck, blade system & drive are designed for those conditions.
Authorised AS-Motor dealers provide product advice, demonstrations, machine handover & ongoing service. Before recommending a mower, the dealer can consider the vegetation, slope, access, area size & expected workload. Use the dealer search to find an AS-Motor partner by location or company name.
AS-Motor ELECTRIC includes battery-powered mulching mowers, professional lawn mowers, Allmähers®, ride-on mowers, rotary mowers & WeedHex weed removers. Depending on the model, selected hand-guided machines are available with EGO or STIHL powerheads. Battery compatibility, runtime & product availability vary by machine and market.
