For non-IMatch attachments, I had some re-welding done to make them conform to my IMatch. Newer attachments are conforming to the SAE standard specs, and are more likely to fit the quick tach's that are now available.
I like the idea that to drop off my ballast box (and pick it up again), I don't have to get on and off the tractor. Same with my carry-all platform. Regardless, much improved over fighting the individual lift arms when un-attaching and attaching (see the thread under safety about kicking, beating, and hammering to remove lift arms) equipment. Worth every penny of the $200, and I use the top hook to bring logs out of the woods, either with chain or logging tongs.
