Abstract
A tillage implement with on-the-go angle and depth controlled discs. The toolbar upon which the discs are mounted is pivotally secured to the wheeled implement frame assembly and may be hydraulically pivoted to raise or lower the discs relative to the frame assembly. In addition, the discs are secured to the toolbar in pairs and are angularly adjustable with respect to each other, and to the direction of motion of the implement, through a pair of hydraulically actuated gears.
Claims11
A tillage implement for attachment to a tractor for towing across a field to be tilled, comprising:
- (a) a wheeled frame assembly adapted to be towed behind the tractor, said wheeled frame assembly having a longitudinal axis;
- (b) a toolbar secured to said wheeled frame assembly, said toolbar being substantially transverse to said longitudinal axis of the tillage implement;
- (c) a plurality of disc assemblies operatively fixed to and laterally spaced along said toolbar, each of said plurality of disc assemblies comprising first and second opposing discs, said discs having an angular orientation, and wherein said first and second discs are angularly adjustable relative to one another and to the direction of travel of the tractor;
- and
- (d) an actuator, for changing said angular orientation of said first and second discs of each of said plurality of disc assemblies.
A tillage implement with on-the-go angularly adjustable discs adapted to be towed by a tractor, comprising:
- (a) a main frame, said main frame having a longitudinal axis;
- (b) a ground wheel assembly pivotally attached to said main frame;
- (c) a first actuator operatively connected to said ground wheel assembly and said main frame for pivotally raising and lowering said ground wheel assembly with respect to said main frame, thereby raising and lowering said implement with respect to a ground surface;
- (d) a toolbar pivotally secured to said wheeled frame assembly, said toolbar being substantially transverse to said longitudinal axis of said main frame of the tillage implement;
- (e) a plurality of disc assemblies operatively fixed to and laterally spaced along said toolbar, each of said plurality of disc assemblies comprising first and second opposing discs, said discs having an angular orientation, and wherein said first and second discs are angularly adjustable relative to one another and to the direction of travel of the tractor;
- (f) a second actuator operatively connected to said main frame and said toolbar for pivotally raising and lowering said disc assemblies with respect to said main frame;
- and
- (g) a third actuator for changing the angular orientation of said first and second discs of each of said plurality of disc assemblies.
A tillage implement with on-the-go angularly adjustable discs adapted to be towed by a tractor, comprising:
- (a) a wheeled frame assembly adapted to be towed behind the tractor, said wheeled frame assembly having a longitudinal axis;
- (b) a toolbar secured to said wheeled frame assembly, said toolbar being substantially transverse to said longitudinal axis of the tillage implement;
- and
- (c) a plurality of disc assemblies operatively fixed to and laterally spaced along said toolbar, each of said plurality of disc assemblies comprising first and second opposing discs, said disc assemblies further comprising first and second torque shafts, each of said torque shafts having an upper end and a lower end, and wherein said first and second discs are rotatably mounted upon first and second axles, said axles extending from said lower ends of said first and second torque shafts, each of said first and second torque shafts extending through and rotatable within first and second bushing sleeves, said first torque shaft having a geared torque arm affixed to said upper end of said first torque shaft, said second torque shaft having a geared torque plate affixed to said upper end of said second torque shaft and in operative engagement with said geared torque arm, said geared torque arm operatively linked to an actuator whereby said first and second discs are angularly adjustable relative to one another and to the direction of travel of the tractor.
