Abstract
A support wheel for an agricultural implement includes a support frame connected with an agricultural harvesting machine and its receiving device; and at least one support wheel connected with the support frame. In a preferred embodiment, the support frame includes first and second supporting arms. The second supporting arm is oriented in a generally vertical direction and is variable in length. In one arrangement, the second support is a lifting cylinder or a telescopic arm and is provided with a damping element. In another arrangement, the support wheel assembly includes at least one steerable support wheel that is pivoted on a pivot shaft by a steering cylinder. A preferred embodiment includes first and second steerable support wheels connected by a coupling mechanism and pivoted about first and second pivot shafts by a common steering cylinder. In yet another advantageous embodiment, the common steering cylinder is operatively coordinated with a steered axle of the agricultural harvesting machine through a control unit.
