AS MOTOR AS 990 TAHR RC High Grass Mower

The AS-Motor AS 990 TAHR RC High Grass Mower: Master of Slopes and Rough Terrain

If your groundscare work takes you to steep slopes, tangled undergrowth, or high-grass meadows, you’ll know that conventional mowing solutions simply don’t cut it. Well, the AS-Motor AS 990 TAHR RC brings a whole new standard to extreme mowing environments—delivering remarkable safety, power, and productivity without placing the operator in harm’s way. With remote-controlled precision, heavy-duty cutting power, and protruding crawler tracks, this compact high-grass mower is tailormade for difficult terrain. Designed and manufactured in Germany by the slope mowing specialists at AS-Motor, the AS 990 TAHR RC helps professionals work faster, smarter, and safer—without turning a single corner.

Built for Steep Slopes and Thick Grass

This high-grass mower has a unique talent for operating effectively in the most demanding environments. Whether mowing uphill or downhill on inclines of up to 50°, the AS 990 TAHR RC maintains full traction thanks to its delta crawler chassis. The external drive tracks provide maximum surface contact, delivering unbeatable grip and stability with no risk of skidding, getting stuck, or components touching the ground. That means minimal soil disruption, smoother manoeuvring, and the ability to approach a slope from any angle. At just 70–80 cm tall, it comfortably fits beneath low-hanging branches and solar arrays—giving you access to areas larger machines simply can’t reach.

Zero-Turn Efficiency with Bi-Directional Mowing

One of the standout advantages of the AS 990 TAHR RC is its zero-turn capability, made possible by a remote-controlled caterpillar drive and very-well-balanced chassis. But it doesn’t stop there—this machine doesn’t just turn easily; it removes the need to turn altogether! Thanks to its even weight distribution and the maximum support width of the drive tracks, it delivers a clean, consistent cut in both directions of travel. You can mow forwards, then immediately reverse over the next line without repositioning. This

reduces operator fatigue, saves time, and allows the mower to handle complex, awkward plots with ease. Precise blade operation and uniform grass discharge patterns make for a neat, mulched finish—even on lawn-like surfaces.

Powerful Cutting, Minimal Fuss

Featuring a rugged cross blade system (already proven in AS-Motor’s renowned AS 940 Sherpa Ride-On Mower), the TAHR RC shreds through dense grass and undergrowth up to 1.5 metres tall. With a cutting width of 90cm, the pendulum swing blades sever the vegetation while an upper bar re-cuts and clears the deck efficiently. This multi-stage mulching system promotes rapid decomposition of clippings, reducing the need for clean ups. The 724cc Briggs & Stratton Professional Series twin-cylinder engine has a maximum power output of 20.1kW (27hp). Even in high-load conditions, it keeps the machine powering through work at speeds of up to 5 kmph in either direction—translating into area coverage of up to 4,500 m² per hour. The cutting height can be adjusted remotely in five stages between 50 mm and 140 mm, allowing you to instantly adapt to varying terrain.

Intuitive Remote Control for Safer Working

Designed for modern professionals, the AS 990 TAHR RC is fully remote controlled with a user-friendly handheld interface that reduces operator strain and enhances safety. The ergonomic remote gives you full directional control—forward, reverse, left, right, or on-the-spot turning—with minimal input. When changing direction, the remote intelligently reverses left/right steering logic, eliminating confusion and shortening the operator’s learning curve. Key status indicators such as blade engagement, cutting height, slope angle and battery level are all clearly displayed on the LCD. The long-range signal allows operators to maintain a safe, comfortable distance of up to 300m, avoiding exposure to noise, heat, flying debris, or unstable footing. This creates a safer, happier and more productive working environment, even in hot weather or on ultra-challenging terrain.

Expertly Engineered, Incredibly Durable

True to AS-Motor’s philosophy, the AS 990 TAHR RC is simple in its design and robust where it counts. From its double 4-edged tubular steel frame to steel-inlaid track belts and heavy-duty belt drives, every component is expertly engineered for unbeatable durability and low maintenance. The Briggs & Stratton engine and hydrostatic transaxles are constructed on proven industrial-grade production lines, ensuring dependable performance day after day, year after year. Servicing is fast and straightforward, with tool-free access to the oil tank and air filter, clearly visible track tension indicators, and a folding engine cover for full vertical access. Blade replacements are economical, and maintenance intervals are generous—with engine oil servicing required after 80 hours under commercial use.

Smart Design for Real-World Use

The AS 990 TAHR RC isn’t over-engineered with excessive electronics or hybrid systems that add bulk and complexity. Instead, it’s a well-balanced machine that keeps things practical. Weighing 482 kg and measuring 152cm (L) x 131cm (W), it’s easily transported by lorry or van. Lashing points and a central lifting hook make loading safe and secure. Triple ejection protection flaps and a double curtain shield the surroundings from flying objects during use. And if working into the evening or in shaded woodland, four optional LED headlights—safely installed under the bonnet—ensure the operator benefits from clear visibility.
