ABSTRACT:
A bucket assembly for a tractor has a plastic bucket in the form of a trough including a rear wall, a top wall, a bottom wall and a pair of end walls. A plurality of strengthening ribs having first and second legs are fastened to the bottom and rear walls of the bucket at respective legs. A mounting plate is fastened to three of the ribs at the rear wall and includes spaced apart rearwardly extending ears for connecting to the conventional bucket supporting arms and tilt cylinders of the tractor. A two piece cutting edge is attached to the ribs at the front of the bottom wall and projects forwardly of the bucket. The bucket also includes stiffeners upset out of the top wall and protective strips extending from the front of the end walls. By selection of the appropriate mounting plate the bucket assembly may be universally adapted for all of the known tractors.
