<p>A tie rod assembly (10) for a steering wheel structure (16) for an agricultural vehicle such as a row crop applicator uses hydraulic cylinders (20) to set the track width of the vehicle. The track width may be modulated between a minimum and a maximum track setting and modified until a desired track width is achieved while the vehicle is in motion and negotiating a turn without affecting toe-in settings. Toe-in settings are maintained by a closed loop series hydraulic system which further has the capability to reinitialize any toe-in setting to a present condition in the event any hydraulic cylinder experiences cylinder drift.</p> |
