Tips to Reduce Track Wear
Rubber tracks are best suited at soil-based job sites with minimal rock and debris. Sharp objects such as
gravel, steel shards, and broken concrete will damage rubber tracks and undercarriage components.
Excessive operation on concrete or asphalt will shorten track life. When storing your machine, keep tracks
away from rain and direct sunlight.
Wash tracks daily to remove foreign objects and abrasive soil from sprockets and idler rollers. Drive slowly
and make wide turns when possible. Regularly check undercarriage components (sprocket, rollers, idler)
for wear and damage. Maintain proper track tension. (See “Check Track Tension and Condition” on
page 147.)
To prevent premature wear, avoid the following:
•
Spinning tracks under heavy load.
•
Turning on sharp objects such as stones, stumps and debris.
•
Quick turns or “spin” turns on asphalt or concrete.
•
Driving over curbs, ledges, and sharp objects.
•
Driving with sidewall edges pressed against hard walls, curbs or other objects.
•
Driving on slopes.
•
Operating on corrosive materials such as salt or fertilizer. Wash immediately.
