Description
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 56° (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.
