A bumper for a backhoe boom includes a plate for mounting to the backhoe, two rods threaded at both ends that are cantilevered away from the mounting plate, and two stacks of rubber plates mounted on the threaded rods on either side of the mounting plate. The two stacks of rubber plates are secured to the threaded rods with nuts. The nuts abut two retaining plates that press against the stacks of rubber plates.
