    Abstract: A tag wheel lift includes first and second brackets, spaced longitudinally and provided with inner and outer legs, with the former being attached to a mounting plate by spacing blocks which provide clearance for nuts for pivot bolts which extend through the legs. One end of a leaf spring for the corresponding tag wheel is pivoted on a bolt or pin extending between the lower ends of the legs of the first bracket, while the other end of the spring is pivoted between a pair of lower links, at the lower rear corner of a rearward offset. A hydraulic cylinder is pivoted on the first bracket, while the piston rod thereof is pivoted between the movable ends of a pair of upper links, on the same pivot which connects the upper links with the lower links.
