ABSTRACT:
A plow having a wheeled frame for towing by a land vehicle. The plow includes a tool carrier pivotally secured to the frame for carrying soil cultivating tools. A ratchet wheel and a lever are pivotally secured to the frame in a side-by-side relationship. A drive pawl is pivotally secured to the lever for pivoting the ratchet wheel in one direction when the lever is pivoted. A holding pawl is pivotally secured to the frame for permitting the rotation of the ratchet wheel with the lever in one direction but preventing the rotation of the ratchet wheel in the opposite direction. A tiebar assembly, having a rocker arm and a lifting arm, is pivotally secured to the frame. A link connects the lifting arm to the tool carrier. A pushrod connects the ratchet wheel to the rocker arm. By manually pivoting the lever, the user of the plow can easily raise and lower soil cultivating tools with an accompanying mechanical advantage.
