Abstract
Abstract Apparatus removably mounted on a standard model agricultural tractor of a type used principally for pulling various implements and for hauling, and to which agricultural implements cannot usually be advantageously mounted at the front of the tractor, the apparatus including a second steering device at and facing the rear and at a side of the tractor which is linked to the tractor's regular steering device. A seat for the driver may be pivoted 180° to one side for constituting a driver's seat when controlling the second steering device or two seats facing in opposite directions may be provided. A second set of pedals, such as a clutch, accelerator, and brake project from the deck of the attachment in the vicinity of the second steering device and are mechanically linked to the regular control pedals. The implements are mounted on a three-point lifting device extending from the rear of the tractor which can then be driven with facility in reverse by a driver at the second set of controls facing the rear and being disposed on one side of the tractor whereby he can view the implement while it is being operated.
