Abstract: A tiller assembly includes a tine assembly that is rotatably connected to a tiller body and the tine assembly includes at least one tine for use in tilling associated soil. A hydraulic system is operatively connected to the tine assembly and includes a hydraulic pump, a hydraulic motor for use in rotating the tine assembly in first and second directions, a control valve, and hydraulic hose for use in communicating hydraulic fluid between the hydraulic pump, the hydraulic motor, and the control valve. The control valve may be positioned on-the-go into a first position thereby causing the tine assembly to rotate in a first direction and into a second position thereby causing the tine assembly to rotate in a second direction. The tiller assembly may also include a roller assembly that has a roller frame pivotably connected to the tiller body. The roller assembly also includes a roller that is rotatably connected to the roller frame and a spring for use in maintaining the roller against the soil.

Abstract: A dynamic drive and brake system is provided. To accelerate the mower in a forward direction, the operator depresses the acceleration pedal, overcoming the biasing force of the acceleration spring. This causes the double idler pulley system to pivot from an inoperative or de-lutched condition to an operative condition. The farther the accelerator pedal is depressed, the more the double idler pulley system pivots and, correspondingly, the more tension is applied to the first belt. The increased tension in the first belt causes the middle pulley member to move in a downward direction and therefore decreases the diameter of the first belt about the double pulley shaft. The movement of the middle pulley member simultaneously increases the diameter of the second belt about the double pulley shaft. This increases the tension in the second belt which tension is absorbed by the idler spring that permits the idler pulley to pivot in a clockwise direction.

Abstract: A mower having a cruise control system is provided. The mower includes a frame, a plurality of wheels including at least a first drive wheel operatively supported by the frame, an engine operatively mounted to the frame, a mower deck operatively connected to the frame, and a drive system for use in transferring power from the engine to the at least first drive wheel. The drive system includes an accelerator pedal fixedly connected to an accelerator rod. The cruise control system mechanically locks the accelerator pedal and accelerator rod in place. This permits the operator to release all pressure from the accelerator pedal (resting the foot of the operator) while maintaining the accelerator pedal in any predetermined position.
