Blade Brake Band Adjustment

NOTE:

The length of the actuator rod is adjusted by

disconnecting the bottom clevis and shortening or
lengthening accordingly.  The standard pre-set length
of the actuator rod is set at the factory at 8-1/4 in.
(209 mm).

After adjustments are complete, check blade

 the 

Blade Brake Action 

in the 

Mainte-

nance Instructions Section.

  If blades do not

stop within five (5) seconds, check the following:

a.

Recheck 1/8 in. (3 mm) gap between stop
block and chassis.

b.

Make sure clutch and brake linkage are work-
ing freely (no binding).

c.

Check the brake band lining.

d.

Check the brake drum on the pulley.  If exces-
sive wear is present, it will be necessary to
replace worn parts.

Blade Clutch (PTO) - Model MD

Clutch Engagement/Belt Tension

The clutch engagement and PTO belt tension are ad-
justed using the clutch actuator rod.  Initially, after in-
stalling a new PTO belt, 

after 10 hours and every 100

hours 

thereafter, check and adjust for the three dimen-

sions in the clutch linkage as shown. 

Adjust the bolt head clearance [1/4 to 3/8 in. (6 to 10
mm)] first, then adjust spring length.  If adjustments are
needed more frequently than 100 hours to maintain the
linkage dimensions, it may suggest problems with pul-
ley wear or belt misalignment.
