A friend and customer of mine brought in her 425 for a deck problem that I sure cant find,She stepped on the non chute side of the deck while getting on the tractor the other day and heard a bang and the deck dropped from lift height to mowing height instantly and now will only lift the chute side of the deck,I have looked till I am cross eyed and see no damage and I am sure its one of those right there in your face simple things to see but it really eludes me,,,Any Ideas??The chute side lifts properly when the hydraulics are applied but the other side hardly moves,
