Good comments. Blocks, and I'd add a 5' or 6' pry bar, make the task easier. At best swapping 3ph implements is a small pain. Today I finally have to take off pallet forks in favour of the box scrapper. Pallet forks and post hole augers must be the worst.
Too bad I didn't finish the fork work before needing the scrapper for several days. Gawdg, who'd of guessed I'd get 15 yards of gravel and 15 yards of top soil the same day as ordered, and followed by two days of rain. Now I've got to deal with the dirt and put the forks back on as well. Black fly are the only reason I didn't finish with the forks. Guess I've got to say that black fly make swapping 3ph implements even worse to get back on subject. A bug shirt can be considered an aid to 3ph mounting, but it's getting grease covered.
I, myself, don't have a problem of too low. My lift will drag the ground, maybe it's the turf tires, but I still block the implements. There's a thread on CTB on this subject which contains some more useful comments.
