Rotate the blade so that the blade is placed at an angle of 90 degrees to the frame. Lower the blade to the ground. While you maintain a light load between the ball of the drawbar and the socket, inch the machine slowly to the rear. Stop the machine and shut off the engine.

Measure the end play that is between the ball of the drawbar (6) and the cap for the drawbar (4). The end play should be 0.6 ± 0.2 mm (0.02 ± 0.01 inch). Adjust the end play, if necessary.

Adjust

1. Support the drawbar and support the circle.

4. As required, remove shims (4) or install shims (4) in order to attain an end play of 0.6 ± 0.2 mm (0.02 ± 0.01 inch).

5. Install two capscrews (5) in cap (2) and adapter (6). Rotate cap (2) by hand. The socket should rotate freely on ball (1) of the drawbar.

6. Check the torque on five bolts (7) that hold ball (1) of the drawbar in place. The correct torque is 500 ± 65 N·m (370 ± 50 lb ft).

7. Assemble the drawbar to the bolster. Tighten bolts (3) to a torque of 720 ± 55 N·m (531 ± 41 lb ft).
