Abstract
A towed implement, such as a cultivator is configured between an unfolded operational position and a folded transport position in which wing sections are pivoted about a vertical axis into a forward direction where they are alongside a telescoping tool bar. Sensors on the cultivator send signals initiating the folding/unfolding sequence to send commands through the implement controller to a tractor controller having a ISOBUS class 3 configuration. The tractor is commanded to forward and rearward movement in synchronism with the folding/unfolding process to steer wing supporting wheel assemblies toward the correct position for the intended transport direction.
Claims3
A method for minimizing stresses on a swivel ground support wheel for an agricultural implement towed by a tractor capable of at least one of commanded forward and rearward movement and having at least one wing frame articulated to be displaced between an unfolded and folded position in which the at least one wing frame pivots at least one of forward and backward, said ground support wheel being connected to the at least one wing frame, said method comprising the steps of:
- initiating displacement between the unfolded and folded positions;
- and,
- commanding the tractor to move forwards and backwards in response to the wing frame displacement in synchronism so that the swivel ground support wheel is steered toward the correct position for the intended transport direction as the wing frame is displaced while minimizing movement of the ground support wheel assembly relative to the ground.
