Farm Implement Having A Frame Supported By A Lift Wheel Assembly And A Pair Of Gull Wings

摘要

A method and apparatus for automating some of the tasks that heretofore required operator action at headland turns or similar events are provided. The present invention automates operation of lift assist wheels and/or gull wings, such as those found on a stack-fold implement, based on the position of the tractor hitch to which the implement is coupled. An operator may control the position of the implement, such as at a headland turn, by raising and lowering the tractor hitch using a remote control. The invention enables the planter to compare the tractor hitch position relative to an implement position and control operation of the implement accordingly without additional user inputs.

主权项

1. For use with a tractor equipped with a hydraulic system and an ISOBUS hitch, a farm implement having a frame supported by a lift wheel assembly and a pair of gull wings, comprising:
a toolbar; a connector for coupling the toolbar to a hitch of the tractor; an ISOBUS connection that facilitates communication with remotes for controlling hydraulic pressure in the hydraulic system; a first electrical input that receives a hitch position signal from the towing vehicle; a second electrical input that receives a frame position signal; an electronic control unit (ECU) that receives the hitch position and the frame position signals and provides a command signal to the remotes of the tractor via the ISOBUS connection to automatically activate the lift wheel assembly to maintain the frame in a level position as the vertical position of the hitch changes.
