Smooth Rubber Tracks
Specifically designed smooth rubber tracks let the RC-30 Turf Edition travel and work on fragile surfaces like turf without leaving a trace. Yet, this machine has the power and traction to work productively in most conditions.
Minimal Ground Pressure
ASV's unique, patented undercarriage technology lets the Turf Edition machines crawl over any surface with minimal ground pressure. For the RC-30, ground pressure is 2.5 psi - about half the ground pressure of a person on foot. Low ground pressure means these machines work with minimal surface disturbance, plus minimal compaction to protect fragile root systems and underground utilities like irrigation lines.
The rubber track itself is the culmination of over 20 years of research and development. It's a lightweight, pliable, yet tough material. A strong Kevlar-like wrap in the center of the rubber track prevents track stretch, so adjustments for track tension are minimal. No steel is used anywhere in the rubber track to avoid the problems of corrosion, delamination and early failure that is common on rubber tracks with steel inserts.
A special smooth green rubber track is also available on Turf Edition models. This unique smooth track offers ultimate protection of refined turf surfaces, such as on golf courses, sports fields and similar turf surfaces. These smooth tracks still offer excellent traction in most ground conditions.
