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 mower unit includes a housing having a skirt portion extending toward the ground, and a covering wall surrounding a plurality of grass cutting blades to define spaces for mulching treatment. The covering wall includes peripheral wall members each curved along a locus of revolution of the blade and spaced from the skirt portion. The peripheral wall member includes a vertical portion descending toward the ground. The vertical portion and the skirt portion have lower ends thereof substantially at the same height over the ground. The blades are arranged transversely of the mower unit. The peripheral wall members are in the form of independent annular wall members provided for the blades, respectively. The annular wall members define spaces for mulching treatment substantially independent of one another. Alternatively, the peripheral wall members may be in the form of annular wall members corresponding to loci of revolution of the blades, respectively, and an adjacent pair of the annular wall members may have at least parts of peripheries overlapping each other. The parts of peripheries are cut so that the spaces of mulching treatment defined by the pair of annual wall members communicate with each other.
