Removing Tine Drive Belt Pulleys

IMPORTANT: Avoid damage! Aeration head flex-links are timed. Timing marks (A) on both flywheel pulleys must line up with reinforcement bracket edges (B) when assembled.

NOTE: To complete the removal of the pulleys, two 3/4 x 3-1/2 in. machine bolts with nuts and lock washers are required.

Bolts holding connecting rods to belt pulleys are left-hand threaded. Refer to the decal on the arm indicating direction of thread.
