Title: Deck attachment and lift system

Abstract: A riding mower has a deck attachment mechanism for use in attaching a mower deck to the mower frame and a deck lift mechanism for use in lifting the mower deck. The deck attachment mechanism forms a four-sided parallelogram and includes a first side formed of a first link and a second side formed of second and third links. The second and third links together form a split link and the third link may be pivoted about the second link into first and second positions. The first link has an effective length L1 and the split link has an effective length L2 when the third link is positioned into the first position and an effective length L1 when the third link is positioned into the second position. The effective length L2 is less than the effective length L1. The deck attachment mechanism also includes a lock bracket and a lock lever to lock the third link into the second position. The deck lift mechanism includes a lift cylinder mounted to the frame and connected to the third link. The lift cylinder is operated to position the third link into the second position as the mower deck is lifted.
