PTO Clutch Disengaged

Blade Brake Band Adjustment

The blade brake is designed to stop the blades with- in five (5) seconds after clutch disengagement. Ev- ery 100 hours of operation verify correct perfor- mance of the blade brake by following the procedure in CHECKING/SERVICING the Blade Brake Ac- tion in this section.

WARNING

It is important to check and maintain blade brake action for safe operation of the ma- chine.

Adjust the working travel of the clutch idler pulley by adjusting the brake band nut:

1.With the clutch disengaged, adjust the blade brake band nut to achieve a 1/4 in. to 3/8 in. (6.5 mm to 9.5 mm) gap between the PTO pul- ley and clutch idler pulley as shown in the Blade Brake Band Adjustment illustration.

NOTE: As the blade brake band/drum wears, idler pulley travel will increase and it will be nec- essary to adjust the brake band nut to maintain the correct 1/4 in. to 3/8 in. (6.5 mm to 9.5 mm) gap. If the gap is greater than this in the disen- gaged position, the PTO belt may not declutch adequately. Every 100 hours of operation check the pulley gap and adjust if necessary.
