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： 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 suspending an implement from a vehicle, such as a lawn and garden tractor. The mechanism includes front and rear supports between the vehicle and implement, the supports being adapted for quick and easy connection. The rear supports include spring-loaded J-pins connectable with the tractor lift linkage. The front support includes a U-shaped member, the base of which is receivable in upwardly opening jaws carried on the implement. The sides of the U-shaped member serve as draft links and are adjustably coupled with a cross member that is receivable in similar jaws carried by the tractor. A latch handle is connected to a bell crank which is provided on the cross member for tensioning the draft links and securing them in their tensioned configuration.

摘要： An improved coupler or hitch assembly of the latch plate type. Angled jaws on the coupler act together with ramps or angled arms on the equipment secured by the coupler to forgive vertical or horizontal misalignment during the coupling operation. The assembly has an automatically engaging latch plate which is held in a closed position by a lock pin. The lock pin also provides frictional restraint for holding the plate in an open position. A lock pin holding mechanism allows relatively unresisted movement of the latch plate from an open to a closed position. Movement of the latch plate is also controlled by a limit tab on the coupler to prevent the lock pin from interfering with the coupler operation.

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 shield for a rotary mower blade drive is received on locating dowels fixed to the blade housing and are retained thereon by a pair of U-shaped latch rods that are either vertically pivotally mounted to the shield or vertically pivotally mounted to the housing. In the case where the rods are carried by the shield, they are located beneath gauge wheel support members which are fixed to the housing and have recesses which receive the rods when the latter are in upright, resiliently deflected conditions wherein they bias the shield against the blade housing. In the case where the rods are carried by the housing, the shield has raised portions which define recesses which receive the rods when the latter are in upright, resiliently deflected conditions wherein they bias the shield against the blade housing. In both cases, the shields are properly located by dowels or pins fixed to the housing.

摘要： A front-mounted rotary mower is coupled to a vehicle by a pair of vertically swingable lift arms coupled between the vehicle and mounting brackets located in a central portion of the mower blade housing. A lift mechanism includes a pair of linkages respectively coupled between the pair of lift arms and the rear of the blade housing. Each linkage includes one link which carries a roller at one end disposed for engagement with the vehicle frame as the lift arms are swung upwardly, which action causes the one link to pivot to effect elevation of the rear end of the housing.
