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.

Abstract: A vacuum unit used to vacuum lawn debris includes a vacuum unit body having at least first and second inlet openings and at least one flap that can be adjusted to selectively cover and open the second opening. The vacuum unit body includes a flap adjustment member that is located within the second opening and that includes a contact surface that contacts the flap. Preferably, the flap adjustment member has one end that is adapted to receive a vacuum hose. The flap adjustment member can be placed into a first position where it causes the flap to open the second opening and a second position where it permits the flap to cover the second opening. The vacuum hose has a handle that can be attached to the vacuum unit handle permitting the vacuum hose to remain permanently attached to the vacuum unit even when the vacuum hose is not being used.

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. 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 translation: 耕耘机组件包括可旋转地连接到耕耘机主体的齿组件，并且齿组件包括至少一个用于耕耘相关土壤的齿。 液压系统可操作地连接到齿轮组件，并且包括液压泵，用于在第一和第二方向上旋转齿轮组件的液压马达，控制阀和液压软管，用于在液压泵， 液压马达和控制阀。 控制阀可以被放置在第一位置，从而使得齿组件在第一方向上旋转并进入第二位置，从而使得齿组件沿第二方向旋转。 舵柄组件还可以包括一个滚子组件，该滚子组件具有可枢转地连接到耕耘机主体的滚子框架。 辊组件还包括可旋转地连接到辊框架的辊和用于将辊保持抵靠土壤的弹簧。 辊具有用于重新包装耕作土壤的接触表面。 弹簧允许滚子框架相对于耕作机构移动。
