Land Pride uses several different types of safety shields for their PTO shafts. One model has 3 small holes around the bell-shaped collar that need to be pushed in order to release the locking tabs underneath. On my new rotary cutter PTO, each tab would re-engage as I moved to the next one. The only solution was to push all three tabs at once which is physically impossible.
After much frustration and cussing, the solution was to insert a 3/8' diameter X 1/2" long set screw (red circle) in each hole and screw it down until almost flush with the outside of the collar. This presses on each locking tab (green circle) at the same time making it possible to slide the collar back on the shaft cover.
To reassemble the collar and tube, you'll need to back the set screw out until it is flush on the underside so it won't depress the locking tab.
I left the set screws in the collar as they fit tight enough to not back out while using the implement.
