ABSTRACT:
An excavator has a dozer blade coupled to transversely spaced first and second fore-and-aft extending drive housings thereof by first and second separate push beams having their respective forward ends universally coupled to the blade. The first push beam has its rear end universally connected to the first drive housing while the rear end of the second push beam is connected to the second drive housing by an angling link which is swingable fore-and-aft so as to cause fore-and-aft movement of the second push beam; a length adjustable jack forms a stabilizer strut which is coupled between the first push beam and the blade so as to maintain the latter in a desired pitch. Individual lift actuators are connected to the push beams for selectively adjusting the latter vertically either together or separately. A side load transfer strut is connected between the forward end of the first push beam and the second drive housing.
