REMOTE LEVELING OF TILLAGE IMPLEMENTS

摘要

An agricultural implement for supporting a plurality of gangs of disk blades extending generally laterally relative to a forward travel direction. The implement has carrier frames pivotally connected to wheel assemblies for controlling the height of the carrier frames relative to the ground through hydraulic actuators acting on the wheel assemblies. The hydraulic control unit enables independent and individual control of each actuator. An electronic control unit (ECU) receives displacement signals from the actuators and stores the signals when the agricultural implement is on a reference surface for synchronized set points. Thereafter any deviation from the synchronized set point is corrected.

1. An agricultural implement spanning a lateral distance relative to a forward direction, said implement comprising:
a plurality of carrier frames, each for supporting a plurality of soil engaging tools; at least one supporting element carried by each carrier frame for variably positioning the carrier frame relative to the soil; an actuator having a base and a variably extending elongated element connected between said each supporting element and said respective carrier frame for varying the position of said respective carrier frame relative to the soil; a sensor determining the displacement of the respective carrier frame relative to the soil at said at least one supporting element; an actuator control unit for each actuator to move said actuator independently in response to a signal input; and an electronic control unit (ECU) establishing a desired synchronized reference signal and comparing it to the signal from each said sensor to send a resultant signal to said actuator control unit for individually varying the position of each elongated element to reach the synchronized reference signal.
