Differential track assembly for a cable laying machine

摘要

A track assembly for a vehicle comprising powered wheels at each side, and an endless track sleeved over the wheels on each side having solely a smooth driven surface friction contact with the associated wheels, whereby when the driving torque overcomes the coefficient of friction the wheels are caused to momentarily slip until the friction drive becomes reestablished and in which novel scrapers are provided to maintain the driven surface clean of mud and rocks and having guides for maintaining the tracks on the wheels.
