I absolutely love mine. It's a matter of just 3-4 minutes to mount or dismount it on the sub-frame (early 90's 4400). Only trouble I had with it was a cracked/broken plate that attaches one operator lever to the hydraulic valves (1st & 2nd pics). No big deal, took about 10 minutes to make/replace. So far, all I've used it for is to plant 18 trees (3rd pic), & bury some concrete, maybe 2-3 hours seat time. Once you get a feel for the hydraulic controls, it's not too hard to operate, but getting two functions on the same stick to run smoothly is a challenge! Down here in southern NJ, the ground is soft, mostly sandy loam & sand, so I can't say how it'll work on rocks & such.
