ABSTRACT:
A levee cutting and forming implement for rice farming which prevents the construction of unwanted bar ditches or ruts. A rigid, generally angularly rearwardly diverging frame supports a pair of rigid, ground engaging levee cutting blades. The elongated cutting blades form a wide mouth at the front of the frame, and converge beneath the frame to a rear levee output. A tine control system comprising a plurality of rigid downwardly projecting Danish tines is employed during the levee cutting process to smooth over the channels adjacent the levee to prevent the formation of bar ditches. The tine system comprises a pair of spaced-apart tine bars from which a plurality of resilient Danish tines project downwardly. A transverse tine control axle journaled for rotation is transversely mounted beneath the frame, and it is controlled by a hydraulic cylinder. A pair of outwardly extending, rearwardly angularly diverging tine control struts emanate from the time control axle and mount the rear tine control bars. The tine bars may thus be hydraulically moved upwardly or downwardly at the rear of the implement during levee forming passes. The associated wheel system may be hydraulically deployed in either a transport position or a clearance position for levee formation. Preferably the wheel and tine system hydraulic cylinders are coplanar.
