Remote-controlled mowers enable efficient and safe mowing of hard-to-reach and steep areas.
At demopark 2025, the tall grass specialist AS-Motor presented a remote-controlled rotary mower that is made for tall grass and steep slopes.
With the AS 990 Tahr RC, you can mow steep slopes faster - without turning.
The new AS 990 Tahr RC knows no "forwards" or "backwards" when mowing. Time-consuming turning after each pass is not necessary. Its sickle-shaped mower deck, which is open on both sides, enables a clean cut in both directions of travel.
The clippings are also always deposited in the same pattern. This results in a consistently uniform and clean cutting pattern, even on lawn-like surfaces.
The cross blade system, which is also installed in the popular AS 940 Sherpa ride-on mower, impresses with its high cutting power. Grass and undergrowth up to 1.5 metres high are easily cut by two pendulum blades at high speed and shredded by the cutter bar above. The large surface area of the grass clippings facilitates their rapid decomposition.
The combination of even weight distribution over the entire length of the crawler tracks and the maximum support width of the drive tracks ensures that the AS 990 Tahr RC has a light and good-natured driving behaviour. Its handling and low centre of gravity in the middle of the machine enable precise driving in shift lines on slopes. The rotary mower offers maximum traction - both uphill and downhill as well as across the slope. Only the external tracks, not the skids or mower components, touch the ground. This greatly reduces the risk of getting stuck. The protruding caterpillar tracks make it possible to approach a steep slope at any angle. No slipping on slopes, rarely necessary turning and the low ground pressure of 0.13 kg/m² protect the ground and the sward.
The precise control of the AS 990 Tahr RC is also intuitive thanks to the remote control, which is limited to the essential functions. Mowing straight lines or turning on the spot when required is child's play. The automatic reversal (left/right) of the control lever saves you having to rethink when changing direction. All this in combination enables an enormous area output of up to 4,500 m² per hour.
When developing new products, the engineers at AS-Motor follow a clear principle: maximum robustness with the lowest possible complexity. The AS 990 Tahr RC fulfils this principle without compromise. The remote-controlled rotary mower impresses with its durability, low susceptibility to faults, simple maintenance, low maintenance costs and uncomplicated repairs. The solid double square tubular steel frame, the tried-and-tested cross blade system from the successful Sherpa series, the reliable hydrostats from Hydro-Gear and the proven engine of the AS 940 Sherpa.
The asymmetrical crawler undercarriage ensures maximum wrapping of the track wheels sprockets and thus prevents the tracks from jumping off. Thanks to the chain tension indicator, you can see at a glance whether the chains are correctly tensioned. If necessary, they can be tightened quickly and easily with a ratchet.
Both the robust belt drive for the blades and travel drive and the clear electronics are less susceptible to faults. Directly accessible service points allow the oil level and air filter to be checked quickly and without tools. For easy access to all units, the hinged engine cover can be opened in seconds and brought into a vertical position. The few and inexpensive wearing parts and the low fuel consumption of approx. 4.5 litres of petrol per hour ensure economical maintenance. Thanks to its compact dimensions, low weight of 482 kg and solid lashing points, the AS 990 Tahr RC can be transported effortlessly - even in a standard Sprinter van.
Remote-controlled mowers enable safe working with a low risk of accidents and significantly reduce the strain on the user. In addition to the classic benefits such as reduced dust and noise pollution and working outside the danger zone, the AS 990 Tahr RC offers additional features for greater user protection: a triple ejection guard, consisting of movable flaps and a double curtain, protects against stone throwing.
An automatic parking brake engages in the event of a standstill or emergency stop and four optional LED headlights ensure good visibility.
The AS 990 Tahr RC will be available from the 2026 mowing season.
