Abstract
A coupling mechanism for connecting a working unit to a tractor body is disclosed which includes an engaging device and receiver brackets for coupling the working unit which is suspended from a lawn tractor body to links extending from the tractor body. The engaging device includes a first rod extending transversely from the links, a second cross rod spaced and parallel to the first cross rod, and a connecting device interconnecting the cross rods. Each receiver bracket includes a receiving groove for simultaneously receiving part of the first and second cross rods therein. The receiving groove includes a first groove portion having a length corresponding to a distance between the two cross rods, a second groove portion extending from the first groove portion in a direction substantially perpendicular thereto, and an opening to the exterior of the bracket. With this construction, the engaging device is not readily separable from the receiver brackets when the lawn tractor moves forward or backward. For disengagement, the second cross rod is slid through the second groove portion and out of each receiver bracket, then the first cross rod is slipped through the first and second groove portions and out of the receiver bracket.
