摘要:
A disk grading terrace plow comprising a plurality of disk units mounted below an angled beam frame which is towed at an angle of 40 to 45 degrees to the direction of tow via a tractor connected to an elevated hitch beam mounted to the said angle beam frame in a lateral position which balances draft torques. Alignment of the said disk units, each comprising a disk blade, shank and attachment structure, along the angled beam frame is such that dirt is excavated from a furrow and discharged both vertically and laterally in front of the next sequential rearward disk. The excavated dirt then continues to shift from disk-to-disk in a compound grading manner until all the dirt is shifted around the rearmost disk blade. The depth of cut for the disk grading terrace plow is controlled by adjusting hydraulic cylinders connected to a front and rear gauge wheel, respectively. Construction or maintenance of a terrace ridge is achieved by grading dirt toward the centerline of the ridge at speeds of 4 to 5 miles per hour wherein limitations associated with using conventional plows is overcome with this invention by grading dirt beyond the throw of a single disk or plow blade with each pass.
