I added this trailer receiver (pic#1) to my TO-20 several years ago as part of a mount for a small backhoe attachment.
It's purpose was to hold the PTO hydraulic pump (pic #2). As the square tubing slides into the receiver the splines on the pump mate with the pto shaft.
The attachment in (pic #3) is used with the bushhog to keep weeds from wrapping around the pto shaft. (Pic #4) is just a ball mount for a trailer. I needed a cover for the pto/orc so I made one (pic #5) from 4" sch 40 pvc and mounted it to the 2" square tubing with unistrut. I welded the unistrut to the 2" tubing and attached the pvc to the unistrut with 1/4 bolts and the threaded inserts that you use with the unistrut. (Pic #6) shows it installed on the tractor. The 4" pipe is a little bulky but had to use that size to clear the grease fittings on the orc. I still need to put a cap on the end of it. I can put it on or take it off in about 10 seconds without any tools. I am going to mount one to the trailer ball attachment so the orc will be covered when pulling a trailer. I would like to hear some more ideas for attachments that would slide into the receiver.
