Abstract: A tillage tool includes a relatively narrow shank that slices through the soil while a ripper point at its lower end fractures and lifts the subsoil. Minimum surface disturbance adjacent the opposite sides of the shank is assured through the provision of a pair of independently mounted down-pressure wheels on opposite sides of the shank that engage and apply constant downward pressure against soil tending to erupt at the top surface. Each down pressure wheel is mounted to the shank assembly by its own leaf spring so that the two wheels react to ground changes independently of one another and without adversely affecting each other. A guide plate associated with each leaf spring prevents twisting of the spring as it flexes and provides stops for limiting the opposite extremes of up and down flexing of the spring.
