A boom is pivotally mounted on the upper carriage and has a dipper arm pivotally mounted at a forward end thereof, the dipper arm in turn having a dipper mounted on its lower end. A double-action hydraulic cylinder is interconnected between the boom and an upper end of the dipper arm to selectively pivot the dipper arm on the boom. Attachment means are mounted on the boom to releasably attach the cylinder thereto upon removal of the dipper arm and its attendant structures for transport of the excavator.
