An agricultural bagging machine including a wheeled frame having at least first and second wheels provided at the forward end thereof and at least third and fourth wheels provided at the rearward end thereof. First, second, third and fourth hydraulic cylinders are pivotally connected to the first, second, third and fourth wheels respectively with the first and second wheels being operated together and independent of the third and fourth wheels. The third and fourth wheels operate together and operate independently of the first and second wheels. A vertically disposed hydraulic jack stand is mounted on the machine at the tow end thereof to enable the second and fourth wheels as well as the tow end of the machine to be raised so that the second and fourth wheels are out of ground engagement. The povital arrangement of the wheels permits the machine to be spin-turned and maneuvered.
