ABSTRACT:
A shield assembly for a power take-off shaft protruding from a tractor has first and second generally vertical, laterally spaced side plates adapted to be positioned on opposite lateral sides of the shaft. A cover extends between the side plates and is adapted to be positioned above the shaft. The cover is pivotable about a horizontal pivot axis and movable in a generally linear direction between a first pivoting position and a second linearly displaced pivoting position. A positioning member is disposed on one of the cover and the first side plate, and first and second stops are disposed on the other of the cover and the first side plate. The first stop and positioning member are spaced approximately the same radial distance from the horizontal pivot axis when the cover is in the first pivoting position, and the second stop and positioning member being spaced approximately the same radial distance from the horizontal pivot axis when the cover is in the second linearly displaced pivoting position. The first stop is positioned at a different elevation relative to the second stop so that a first tilt position of the cover is at a different angle than a second tilt position of the cover.
