A working platform that can be removably attached to a front portion of a utility tractor is provided in which the platform is at least horizontally adjustable, is sized to allow a user to move about on the platform, and the tractor can be controlled by a user with controls located on the platform. In addition, an automatic steering system may be included that allows the tractor to remain generally along a preselected course, such as between rows of trees or other objects. As the tractor moves down the row of an orchard, the platform can be adjusted so as to be in an appropriate position for performing work on the tree.
