  • Automatic connection mechanism for mid-mounted implement
    Patent number: 8234847
    Abstract: An automatic connection mechanism for a mid-mounted implement to a tractor is disclosed. The automatic connection mechanism includes a rear lift linkage pivotably attached to the tractor, that automatically and releasably engage the rear of the implement. The forward lift linkage is pivotably attached to the front of the implement, and automatically and releasably engages the forward end of the tractor. A PTO coupling member also is attached to the rear lift linkage to engage an opposing PTO coupling member on the implement.
