Mounting rotary cutting deck to lift arm

A mounting device to connect a rotary cutting deck to a lift arm includes a bracket having a first pivoting connection and a second pivoting connection parallel to the first pivoting connection. The first pivoting connection is connected to the lift arm and the second pivoting connection is connected to the rotary cutting deck. The pair of pivoting connections allow the deck to pitch. The bracket may be channel shaped and may have an opening or slot through which the lift arm extends. Additionally, a T-shaped pivot pin provides a third pivoting connection between the lift arm and bracket, the third pivoting connection being perpendicular to the first and second pivoting connections.
