Price sounds good, and in an earlier reply, I did not mean to indicate that one type of hitch or the other was better. Like I said, I only have experiance with the 3pt and I was quessing that with a sub frame mount, that you would have to remove the lower 3pt "arms" & linkage for installation. As for the top link issue, on my unit the tractor top link was removed and there was a ridgid part of the BH frame that went to the top link hole on the tractor. This provided a ridgid mount allowing the BH outriggers to transfer the tractor weight for digging (down) pressure.
