AS MOTOR AS 990 TAHR RC High Grass Mower

AS-Motor AS 990 TAHR RC: Remote-Controlled Power for Demanding Mowing Work

When grass gets tall and terrain gets tough, it takes more than an ordinary mower to make the cut. The AS-Motor AS 990 TAHR RC is a purpose-built remote-controlled mower designed to thrive on slopes, in dense vegetation, and across awkward areas where traction and safety matter most. Combining high-end German engineering with a clever, no-nonsense design, this machine takes the strain out of high-grass mowing. From very steep banks to undergrowth-filled plots, it helps professionals cut faster, work smarter, and remain safe—without sacrificing precision or performance.

Designed to Master Sharp Slopes and Uneven Ground

The TAHR RC is not just slope-capable—it was made for the job. Its ability to tackle gradients up to 50 degrees without slipping or skidding is thanks to a carefully balanced delta crawler chassis and full-length drive tracks that distribute weight evenly. These protruding crawler belts provide outstanding grip and control, with no mower components dragging on the ground. You can approach a slope head-on, from the side, or at any angle you choose, and still maintain stability. And with a compact overall height of just 70 to 80 cm, it’s ideal for navigating beneath tree branches, solar arrays, and other low-clearance obstacles where larger mowers simply can’t reach.

Cut Forwards or Backwards—No Turning Required

Where conventional mowers waste time with awkward manoeuvres at the end of every row, the AS 990 TAHR RC keeps things moving. Its rotary deck is open on both sides, enabling clean, consistent mowing in both forward and reverse. That means no turning, no wasted effort, and a perfectly mulched finish across the entire area. It’s an especially valuable feature when working in confined or irregular spaces, as you can simply reverse direction and continue cutting—saving time, protecting the turf, and reducing user fatigue. Combined with a zero-turn capability, this bi-directional mowing makes the TAHR RC an incredibly efficient option for professionals facing complex terrain.

Exceptional Cutting Power in Overgrowth and Long Grass

Whether you’re clearing overgrown pastures or taming neglected hillsides, the TAHR RC delivers the muscle you need. It features a powerful cross blade system with two pendulum swing blades that cut through tall grass and thick vegetation up to 1.5 metres high. A solid upper blade bar then recuts and clears the clippings, helped along by a stainless steel mulching baffle. This layered mulching approach accelerates decomposition and leaves an even spread of material across the surface.

Driven by a 724cc Briggs & Stratton twin-cylinder engine, the mower has a maximum power output of 27hp. It maintains full speed and cutting efficiency even under high loads. With a cutting width of 90 cm and top speed of 5 km/h in either direction, the TAHR RC can cover up to 4,500 m² per hour. Cutting height is adjustable via remote control between 50 mm and 140 mm, allowing on-the-go changes to suit the terrain beneath you.

Operate at a Distance with Safe, Simple Remote Control

There’s no need to walk through thorns, trip hazards, or along sloping surfaces with a handheld brushcutter. The TAHR RC puts the operator safely in control from up to 300 metres away. Its professional remote control unit is intuitive, responsive, and stripped of unnecessary clutter. Directional steering is smooth and logical—when you change direction, left and right steering inputs adjust automatically, so your controls always feel natural.

The LCD display keeps you informed with real-time feedback on blade status, cutting height, battery level, and slope angle. Combined with the machine’s steady handling and well-balanced design, this setup allows for confident operation even on awkward or remote patches of ground. The result is not only improved safety, but higher efficiency, faster learning for new operators, and reduced strain over long mowing sessions.

Built to Last with Durable, Service-Friendly Construction

From the ground up, the AS 990 TAHR RC reflects AS-Motor’s commitment to robust, field-ready design. The frame is made from solid double-walled tubular steel, while the track belts include reinforced steel inlays for added strength. A quick-tension system with visual indicators helps ensure proper track performance, and the engine and hydrostatic drive are drawn from reliable, large-scale industrial production.

Every detail has been designed with easy servicing in mind. The engine cover lifts to a vertical position in seconds, offering immediate access to the core mechanical components. The oil level and air filter can be checked tool-free, while key service points are simple to locate. Blades, belts, and wear parts are easy and affordable to replace. Maintenance intervals are generous—just 80 hours for the engine oil and longer still for the hydrostatic drive.

Compact, Lightweight, and Ready to Work Anywhere

Weighing in at 482 kg and measuring 152 cm (L) by 131 cm (W), the TAHR RC fits easily in the back of a van or on a small flatbed. Lashing points and a central lifting hook make transportation straightforward and safe, while the compact size makes it ideal for contractors working across multiple sites. Despite a modest footprint, this machine brings professional-grade cutting power wherever it goes.

To keep both user and surroundings safe, the mower is equipped with triple ejection protection—including movable flaps and a heavy-duty double curtain. Optional LED headlights, safely housed under the bonnet, ensure the machine remains visible in dimly lit conditions such as woodland or late-evening sessions.

Efficient, Practical and Economical to Run

The AS 990 TAHR RC High Grass Mower is an incredibly efficient machine, offering serious levels of performance. Fuel consumption remains low even under demanding conditions—averaging around 4.5 litres of petrol per hour. Because it skips the complexity of hybrid power systems, electronic sensors, and hydraulic hoses, there’s little to go wrong and less to maintain. What you get instead is reliability, straightforward operation, and low long-term ownership costs.

With few wear parts—just the swing blades, blade bar and drive belt—and an economical price point for a professional-grade machine, the TAHR RC delivers excellent value for money. Its high area coverage, removal of physical strain, and minimal downtime help reduce labour costs and increase output on every job.
