TILLAGE IMPLEMENT WITH ENHANCED BLADE GANG ADJUSTABILITY

摘要

A tillage implement has a main frame provided with ground-engaging wheels that support the main frame at a selected height above the ground. Tillage shanks may be provided on the main frame and, if so, have their depth of penetration into the ground determined by the selected height of the main frame. Gangs of freely rotatable circular blades are carried on the main frame for both fore-and-aft angle adjustment relative to the main frame about respective upright pivot axes and up-and-down depth adjustment relative to the main frame about respective horizontal pivot axes. Such angle and/or depth adjustments can be carried out on-the-go from the tractor seat and without raising or lowering the main frame such that if tillage shanks are provided on the main frame, the working depth of the tillage shanks can remain unchanged as the gangs are adjusted.

主权项

1. A tillage implement comprising:
a substantially rigid main frame; a hitch coupled to and extending forwardly from a front portion of said main frame with respect to a direction of travel of the main frame; a blade gang comprising a plurality of spaced-apart blades rotatable on a common blade rotation axis; and a gang support system for coupling said blade gang to said main frame, wherein said gang support system comprises a gang angle actuator and a gang depth actuator, wherein said gang angle actuator is configured to pivot said blade gang relative to said main frame on a substantially upright gang angle pivot axis to thereby adjust the angle of said blade gang relative to the direction of travel of said tillage implement, wherein said gang depth actuator is configured to shift said blade gang upward and downwardly relative to said main frame to thereby adjust the depth of said blade gang.
