摘要： 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.

摘要： A riding mower comprises a raising and lowering mechanism (30, 33, 100), the raising and lowering control lever (27), and a PTO mechanism (17a, 17b) operated by a clutch lever (29). When the raising and lowering mechanism (30, 33, 100) reaches a predetermined height, a operatively connecting mechanism (5) transmits, to the raising and lowering control lever (27), a return-to-neutral displacement for returning the raising and lowering control lever (27) to the neutral position, and transmits, to the clutch lever (29), a disengaging displacement for returning the clutch lever (29) to the disengage position. A first adjusting operation member (55a) adjusts a triggering displacement at which the raising and lowering displacement is transmitted to the raising and lowering control lever (27) as the return-to-neutral displacement. A second adjusting operation member (55b) adjusts a triggering displacement at which the raising and lowering displacement is transmitted to the clutch lever (29) as the disengaging displacement.

摘要： A mid-mount mower including a body frame supported above the ground by front wheels and rear wheels, and a mower unit vertically movably suspended from the body frame between the front wheels and rear wheels. The mower unit includes a mower deck having a top board, and a front wall, side walls and a rear wall depending from the top board. The mower deck has a rearwardly opening recess formed in a sideways middle region at a rear end thereof. A mower input shaft is disposed on the top board for transmitting power to the rotary blades juxtaposed inside the mower deck to be rotatable about three vertical axes arranged sideways. The mower input shaft extends longitudinally of the body frame and has a rear connecting end. A PTO shaft is provided in a rear transmission mechanism that drives the rear wheels. The PTO shaft extends longitudinally of the body frame and has a forward connecting end. A relay transmission shaft has one end thereof connected to the connecting end of the mower input shaft through a front universal joint, and the other end connected to the PTO shaft through a rear universal joint. The recess is recessed longitudinally of the body frame to an extent forwardly of the rear universal joint to receive the rear universal joint when the mower unit is raised.
