Abstract: A speed control system and method of assembling such a system for a power equipment vehicle such as a lawn mower. The speed control system comprises a speed control bail that pivots with respect to the vehicle handle bar, a pivot rod, and a cover. In order to increase the speed of the vehicle the operator pushes the speed control bail in the forward direction and in order to decrease the speed of the vehicle the operator pulls the bail in the backward direction. Assembly of the system on to the vehicle handle bar does not require the use of hand held or power tools thereby reducing manufacturing time and ultimately reducing production costs.

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. The roller has a contact surface for use in repacking the tilled soil. The spring permits the roller frame to move with respect to the tiller body.

Abstract: A method of manufacturing injection-molded components having complex features is disclosed. Prior methods typically require the use of a three-piece mold system to form an injection molded component having a complex feature, such as a lawn mower hood having a parabolic shaped front. With the development of a new rigid type of reflective material the present method can thereby utilize a two-piece mold system to form an injection molded component having complex features such as a lawn mower hood having a C-shaped open cavity located at the front of the hood.

Abstract: A starter mechanism for an internal combustion engine having a spring that is wound during the starting operation of the internal combustion engine. As the operator pulls the starter rope of the engine the starter spring begins to wind creating a force within the spring. Once the spring force overcomes the compression force of the piston the spring will unwind thereby turning the crankshaft of the engine and consequently starting the engine. The starter rope is returned to the housing of the starter mechanism by the use of a rope return spring.

Abstract: A modular engine design system utilizes selectively replaceable components whereby a family of related engines having varying power outputs may be produced. A first series of engines utilizes a common piston operable in a cylinder of first predetermined dimensions. The engine design may utilize a first or second crankshaft/connecting rod combination to vary the power output. A modified engine design utilizes a second cylinder in addition to the first cylinder. A second series of engines utilizes a larger piston operable in a cylinder of second predetermined dimensions. The second series of engines shares a common engine design scheme with the first series of engines. However, corresponding parts are adapted for use with the larger piston/cylinder combination. The second series of engines may likewise utilize a first or second crankshaft/connecting rod combination to vary the power output. Within each series of engines, modular design concepts are utilized to provide a range of power outputs.

Abstract: A tine assembly for a cultivator includes a first tine member having a plurality of radially extending non-planar tines. At least two tines on each tine member differ in shape from the remaining tines. The tine assembly may include a second tine member which is shaped like a mirror-image of the first tine member. When assembled on a shaft, the second tine member is off-set from the first tine member so that tines on alternating tine members contact the ground as the shaft rotates.
