I have a Kubota
L4600 and a Land Pride 6' bushhog. It used to take me 10-20 minutes to put it on and at least 10 to get it off. This involved an entire swearword Thesaurus plus a sledgehammer and a couple 2x4s.
The process is exacerbated by the fact the the garage I had built was 1.5' shorter in each dimension than I ordered, so the tractor has to back in at a 45 degree angle, which makes lining up a ***** (since the garage is fully Tetrised with other stuff and turning takes some planning).
The hitch arms are only just able to go wider than the pins on the BH - no slack at all. So I removed the pins from the bushhog and welded a couple of steel arms to the deck (and some reinforcements) and now the arms go BETWEEN 2 sets of holes and I slide a pin in once they are aligned. Now I can hook it up in as little as 5 minutes. And disconnecting only takes 2!
Sprained my shoulder patting myself on the back.
