AS 990 Tahr RC: The Revolution in Steep Slope Mowing
Mowing Steep Slopes Just Got Easier – And Smarter
Professionals in landscaping, municipal maintenance, and environmental services know the challenge: mowing dense vegetation on extreme slopes is physically demanding, time-consuming, and dangerous. Traditional brushcutters and ride-on mowers quickly reach their limits. Turning after each pass reduces efficiency. Operator fatigue, mechanical strain, and safety concerns are constant factors.
That’s where the AS 990 Tahr RC steps in.
Engineered for maximum output and total control, this remote-controlled high grass mower with hydrostatic crawler tracks delivers high-performance cutting on slopes up to 50° (119%). Thanks to its open rotary mower deck and bi-directional cutting system, there’s no need to turn after each pass.
More Coverage. Less Turning. Maximum Efficiency.
The AS 990 Tahr RC was built with a clear purpose: maximise area output while reducing strain.
The bi-directional rotary deck, open on both sides, provides the same high-quality cut forward or reverse. No turning required after each row. Clippings are evenly distributed, promoting faster decomposition and protecting the soil.
No turning at row ends = time saved
Clean results even in grass over 1.5 m tall
Symmetrical blade system: 2 pendulum blades + solid blade bar
Cutting height adjustable via remote: 50–140 mm, 5 steps
The result: efficient mowing, consistent mulch distribution, and a visibly clean finish — even on semi-formal green areas.
Built the AS-Motor Way: Simple. Robust. Reliable.
Every detail of the AS 990 Tahr RC follows AS-Motor’s design philosophy: simple engineering, durable components, and maximum serviceability.
Tubular steel frame with double 4-edge design
Industrial-grade hydrostatic track drive
Folding engine hood for full access
Open machine layout for fast maintenance
Track tension indicator integrated into the chassis
No over engineered electronics. No plastic gimmicks. Just a professional-grade machine, precision-built for real-world applications.
Exceptional Performance on Every Slope
With a slope rating of up to 56°, the Tahr RC easily outperforms conventional ride-on mowers. The crawler tracks provide strong traction, stability, and low ground pressure of just 0.13 kg/cm², ideal for embankments, dykes, or water edges.
Cutting dense, tall vegetation becomes a one-person job — fast, effective, and safe.
Easy to Maintain. Easy to Transport.
Service access is quick and intuitive. The engine hood folds open, and the simple layout allows access to all key components. Long maintenance intervals reduce downtime:
Engine oil every 80 hrs
Hydrostatic oil: up to 800 hrs
V-belts & blade system: easily accessible
At 482 kg and 152 × 131 cm footprint, the Tahr RC fits onto standard trailers and is easy to move between job sites.
