    摘要: A mower deck comprises an auxiliary source of pressurized air in order to avoid clipping buildup under the mowing deck, most particularly at the trailing edge of the discharge chute. The auxiliary source of air comes through a cloverleaf shaped hole in the mower deck. The spindle is mounted to the mower deck through this hole, as in conventional mowers. However, unlike conventional mowers, because the hole in the mower deck has a cloverleaf configuration air can flow through the corner portions of the cloverleaf configured hole and act as an auxiliary source of air even though the spindle is mounted to the mower deck through the hole.

    摘要: A replaceable mower blade assembly for attaching to a rotatable spindle, motor, or engine crankshaft is provided. The blade assembly includes a mounting member having a plurality of ends extending from a central bore that is configured to receive the spindle, motor, or engine crankshaft. Each end includes an indexing aperture and a plurality of caps. A locking mechanism is operatively connected to the mounting member, and each arm of the locking mechanism includes a pin. A cutting blade is removably attachable to each end of the mounting member and the cutting blade includes an indexing aperture and a plurality of keyhole apertures. Each pin of the locking mechanism is insertable and engageable with an indexing aperture of both the mounting member and the cutting blade for positively securing each cutting blade.

    摘要: An electronic control system for shifting the direction in an off road vehicle such as a lawn and garden tractor or a utility vehicle is disclosed. The control system consists of a control mechanism that activates a control circuit that in turn activates an actuator to shift the transmission. The control mechanism receives inputs from the operator and sends the appropriate output to the control circuit which thereby actuates the actuator. The control system further includes a sensor that senses neutral or not neutral. The sensor additionally supplies a neutral or not neutral input to the control mechanism. The combination of the input from the operator and the sensor indicates the direction of the vehicle.

    摘要: A lawn mower blade having a thickness of approximately 0.075 inches comprises a main body, an elevational profile, and end portions equidistant from the center of the blade. The elevational profile consists of a raised portion that reaches a height at the plateau portion at the center of the blade. The elevational profile increases at an angle &agr; as the end portions approach the plateau. Each of the first and second end portions has a cutting edge portion. The height to blade thickness ratio is at least two-to-one. Further, since the mower blade is generally not heat treated, ribbing is added to the mower blade to provide strength.

    摘要: A power assisted, vacuum actuated steering system with a rotary valve and vacuum actuators. The rotary valve has two identical discs which each include grooves and channels for communicating the vacuum pressure to the vacuum actuators. The relative rotary motion of the two discs causes the vacuum pressure to pass to the vacuum actuators to assist the steering of a vehicle. A set of springs and spring arms biases the discs to a central, neutral position.
