A tiller assembly (30) includes a tine assembly (36) that is rotatably connected to a tiller body (34) and the tine assembly (36) includes at least one tine for use in tilling associated soil. A hydraulic system (50) is operatively connected to the tine assembly (36) and includes a hydraulic pump (32), a hydraulic motor (42) for use in rotating the tine assembly (36) in first and second directions, a control valve (44), and hydraulic hose for use in communicating hydraulic fluid (48) between the hydraulic pump (32), the hydraulic motor (42), and the control valve (44). The control valve (44) may be positioned on-the-go into a first position thereby causing the tine assembly (36) to rotate in a first direction and into a second position thereby causing the tine assembly (36) to rotate in a second direction. The tiller assembly (30) may also include a roller assembly (70) that has a roller frame (72) pivotably connected to the tiller body (34). The roller assembly (70) also includes a roller (78) that is rotatably connected to the roller frame (72) and a spring for use in maintaining the roller (78) against the soil. The roller (78) has a contact surface for use in repacking the tilled soil. The spring permits the roller frame (72) to move with respect to the tiller body (34).
