ABSTRACT:
A trencher for mounting on a conventional three point hitch of a tractor. The trencher is driven from the power takeoff of the tractor and uses the hydraulic system of the tractor to operate a hydraulic cylinder for raising and lowering the boom and digging chain of the trencher. A power transmission system is provided using interchangeable belts and pulleys for selectively changing drive ratios for driving the digging chain. The boom is telescoping and can be lengthened to achieve a deeper digging depth through turning of an adjustment rod. The boom is spring-loaded for absorbing shocks delivered by the chain to the boom.
