Polkchop, I belive that the RK55 uses the Cat II hitch so there shouldn't be any issue. I bought the $89 Cat I for my RK37 and as kkilli said, it just doesn't work. They sent someone from the store to try getting it to work and after a couple hours gave up and told me I could return it. The bushing on the rotary cutter is just too large in diameter to fit in the hook plus the frame of the cutter hits the bolts that attaches the hook to the quick hitch. I decided to keep the hitch and do some modifications to get it to work. I finally got a smaller bushing for the cutter and that worked but still a close tolerance between the frame and the mounting bolts. I finally found a new hook on Amazon that addresses the problem by the hook opening being larger so that the original cutter bushing will fit down in it and the mounting bolt area of the hook is beefier and drilled to give more space between the cutter frame and hook bolts.
Notice the built up area at the back of the hook. The mounting holes are drilled in that area pushing the hook out away from the frame about 3/8 inch. This is the only hook I found that has that.......Don
