Clamp two C-clamps onto the front of the blade circle (1) and the drawbar (2). This will fasten the blade circle and the drawbar together. Tighten the two C-clamps until the wear strips (3) are in contact with the top of the blade circle and the wear strips (3) are in contact with the bottom of the drawbar.
Lower the blade to the ground. Stop the engine.
Measure the distance (A) that is between the top surface of the blade circle and the bottom surface of the drawbar. Replace the wear strip (3), if the distance between the top surface of the blade circle and the bottom surface of the drawbar is less than 1.5 mm (0.06 inch).
Inspect the wear strip (3). Inspect the drawbar. The wear strip (3) should be in complete contact at all points with the blade circle. If the wear strip (3) is not in complete contact with the blade circle, replace the wear strip (3).Blade Circle to Shoe Clearance
Rotate the blade. Place the blade at an angle of 90 degrees to the frame.Note: Install the C-clamps before you lower the blade to the ground.

Measure the clearance (B) between the bottom of the circle (1) and the top of the shoe wear strip (7). Maintain a maximum clearance of 0.5 mm (0.02 inch). Maintain the proper clearance by adding shims (8) or by removing shims (8).Note: The proper clearance will permit the blade circle to rotate for 360 degrees.Adjust the circle shoes (9) one at a time.
Loosen shoe mounting fastener (6). Remove shoe mounting fastener (4) and remove shoe mounting fastener (5).
Add shims or remove shims, as required.
Install shoe mounting fastener (4) and install shoe mounting fastener (5). Tighten the shoe mounting fasteners.
After all the circle shoes (9) have been adjusted, check the circle shoes (9) for proper clearance. If necessary, perform adjustments to the circle shoes (9).Note: After all the adjustments have been performed, the blade circle (1) must rotate freely without binding .Circle Pinion and Circle
Note: The engagement of the circle pinion and the circle teeth is determined by the adjustment of the circle shoes. Clean the circle and the pinion. Remove any dirt and any abrasive material. This will reduce wear to the circle pinion and to the circle teeth. Also, this will improve the accuracy of the adjustment of the circle shoes. After the adjustment, apply
