摘要： A hitch structure includes a pair of arms each having their opposite ends vertically pivotally connected to a vehicle and an implement. The arms each include first and second sections pivotally inter-connected to each other at a location between the vehicle and an adjacent end of the implement. A stop block is carried by each first section and limits the flexure of the sections about their pivotal inter-connection. The remote end of the implement is supported on a pair of caster wheels and flexible members support the adjacent end of the implement from the arms. Lift actuators are connected to the arms and are operable to lower the first sections of the arms to the extent that the adjacent end of the implement rests on the ground.

摘要： A mowing mechanism having a spindle rotatively driven by a power source, a blade having a radially inner portion coupled for rotation with the spindle and a radially outer portion for cutting vegetation, a housing within which the blade rotates, and a disc operatively carried within the housing for rotation with the blade and having a radially outer portion spaced above the blade. The disc includes an inner portion extending radially inwardly from the outer portion to a position proximate the blade, the inner and outer portions of the disc serving to confine air and clippings near the outer portion of the blade. The rotating disc prevents accumulation of the grass clippings beneath the disc and housing, and enhances airflow within the housing due to viscous drag or friction between the disc and the air within the housing. Deflectors carried by the disc are designed to further enhance airflows and generally deflect clippings back toward the blade for mulching.

摘要： An improved knob for attachment to a lever or the like having a knob body with a cavity formed therein, an extension operatively attached to the body and being biased toward the cavity. Operatively attached to the extension is a projection for engaging a mating portion on the lever and a tapered portion for enabling the knob to be easily removed from the lever. The preferred knob has the extension connected to the knob body so that the extension does not project very far below the cavity entrance. The knob of the present invention is preferably manufactured by injection molding in a single step operation. Once cured, the knob is removed from the mold in condition for assembly on an appropriate lever or the like. To effectuate assembly, an assembler simply places the knob on the lever or the like until the projection engages a mating portion thereof.

摘要： A mower having a belt tensioner that includes a belt engaging primary pulley swingably supported by a primary arm. A rod coupled to the arm carries a spring that acts to push the pulley into engagement with the belt. The rod acts to pull the pulley away from the belt to release the tension in the belt for removal of the belt. A handle attached to the rod is turned by the operator to positively swing the pulley away from the belt. The handle may also be gripped by the operator's hand to lift that portion of the deck during operation to avoid gouging irregular ground conditions or striking obstructions.

摘要： A mechanism for mounting a wheel to a mower deck having a mounting arm carrying a bolt. First bushings fitted within the wheel rotate about a sleeve fixed to the bolt. Second bushings adjacent the first bushings transfer axial forces from the wheel to the mounting arm. The second bushing is recessed within the first bushings in one embodiment, and within the wheel in another embodiment. Seals are formed between the second bushing and the first bushing in one embodiment, and between the second bushing and the wheel in the other embodiment in order to keep dirt and debris from coming between the contacting surfaces during operation.
