Guys, my friend had a pulley break which knocked out one of his hydro pumps on a zero-turn. He was in a ditch and had no way to push the machine out. He didn't realize he needed to release the hydro pumps. He towed the machine with a tow strap about 30 yards. Is there any way to tell if he may have damaged the transmission? If he damaged it, is this something he would notice immediately or would it show up later? Thanks for any help/ideas.
