ABSTRACT:
A farm apparatus is disclosed herein which includes a tool bar for mounting various farm attachments, such as planters, thereto. A first pair of wheels are mounted at one end of the tool bar and are oriented to permit transportation of the tool bar along its longitudinal axis. A second pair of wheels are mounted at the second end of the tool bar, and are castered to permit movement of the tool bar either along or perpendicular to the longitudinal axis. The first and second pairs of wheels are operable to be raised to permit the farm attachments mounted on the tool bar to engage the ground. An arm is pivotally mounted to the tool bar having a first position parallel to the tool bar for transporting the apparatus to and from the field and a second position perpendicular to the tool bar for use of the apparatus in the field.
