hi GeneD14,
great idea but one thing prevented me from welding a clevis hook to my drawbar. when backing up the chain would seem to slide out of the clevis hook. too much dismounting the tractor to reconnect the chain for me. my solution to help prevent this was to use 3 or 4 links of chain and a clevis hook pinned into the drawbar. by having the clevis hooks slot opening geometry variable to pull direction I have to dismount the tractor to disconnect the chain.
awesome drawbar!
