<p>Cushioned Bulldozer Blade The push arms of a bulldozer assembly are mounted outboard of the track roller frames of a tractor and a cushioning cylinder is interconnected between each push arm and track roller frame. This arrangement thus avoids the problem of imposing loads on the main frame of the tractor to which the push arms are normally connected and permits cushioned loads to be transmitted to a pivot shaft pivotally mounting the track roller frames on the main frame.</p> |
