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.
