Abstract
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.
Claims20
An apparatus comprising:
- a lift arm having a first end connected to a traction vehicle and a second end having a socket;
- a T-shaped pivot pin having a post inserted into the socket and a crossbar;
- and
- a channel shaped bracket connecting the T-shaped pivot pin to a rotary cutting deck, the channel shaped bracket having a first pivoting connection allowing the bracket to pivot with respect to the T-shaped pivot pin on a first pivot axis, and a second pivoting connection allowing the bracket to pivot with respect to the rotary cutting deck on a second pivot axis parallel to the first pivot axis.
A mounting device connecting a rotary cutting deck to a lift arm comprising:
- a bracket having a first pivoting connection and a second pivoting connection parallel to the first pivoting connection;
- the first pivoting connection connected to the lift arm and the second pivoting connection connected to the rotary cutting deck;
- and
- a slot in the bracket through which the lift arm extends to limit pivoting of the bracket with respect to the lift arm.
