ABSTRACT:
A deck tilting device includes a deck, a support frame and a deck tilting mechanism for selectively raising respective ends of the deck. The deck tilting mechanism comprises an operating member and two linkages. The operating member is mounted on the frame below the deck and is longitudinally movable relative to the frame. One of the linkages is located between the operating member and each end of the deck, each linkage including a connecting member pivotally mounted on the support frame and forming a pivotal link between the operating member and the deck. Longitudinal movement of the operating member towards one end of the deck results in corresponding movement of the respective connecting member and raising of the respective end of the deck.
