By providing a hydraulic system for configuring an angle of rotation for smoothing tools of a harrow that is predetermined for a tilling session, hydraulic pressure of the hydraulic system may be maintained (and not adjusted) to allow the hydraulic system to actuate during the tilling session by tilling forces encountered by the smoothing tools. As a result, the angle of the smoothing took may change during the tilling session, thereby allowing excessive plant residue encountered by the smoothing tools to be passed over to minimize plugging or bunching.

System for equalizing pressure on smoothing tools of a harrow

By providing a linear actuator in communication with a slide bar disposed in a channel, and by configuring multiple bars of a harrow to achieve an angle of rotation defined by the slide bar, the angle of rotation for smoothing tools of the harrow may be precisely controlled by the linear actuator. As a result, an infinite range of downward angles may be available for the smoothing tools for achieving various effects with the soil.

System for adjusting smoothing tools of a harrow using a linear actuator

An agricultural tillage implement and method for adjusting the angle of smoothing tools of a harrow according to a present geographic location are disclosed. The agricultural tillage implement includes a main implement frame and a soil finish system having the harrow support in a trailing position with respect to the main implement frame for smoothing the soil tilled by ground-engaging tillage tools. A control system is configured to actuate a hydraulic system to define the angle of a first set of ground-engaging tillage tools in response to the percentage of plant residue at the present geographic location according to a stored electronic map.

System for adjusting smoothing tools of a harrow according to location

An agricultural tillage implement constructed to condition crop residue and cultivate the conditioned crop residue. The tillage implement includes a first residue conditioner and a second residue conditioner pivotably attached to a frame of the tillage implement. The first and second conditioners are movable independent of each other and of the frame such that an operator may raise and lower the first and second conditioners relative to the frame to change the depths of the conditioners.
