ADJUSTMENTS

Step 2 - 

Blade Brake Band Adjustment

After the maximum pulley travel is set, adjust the 
working travel of the clutch idler pulley by adjusting 
the brake band nut and make the following adjust-
ment as needed:

1.  Adjust the blade brake band, using the adjust-

ment nut until pulley travel is approximately 
5/8 in. to 3/4 in. (16 mm to 19 mm) from en-
gaged to disengaged.

NOTE:

  As blade brake band/drum wears, pulley 

travel will increase and it will be necessary to 
adjust the blade brake band nut to maintain 
these dimensions.

CHECKING/SER-

VICING

 the 

Blade Brake Action

 in this section.  

If blades do not stop within five (5) seconds, 
check the following:

a.  Make sure clutch and brake linkage are 

working freely (no binding).

b.  Check the brake band lining for wear.

c.  Check the brake drum on the pulley.  If exces-

sive wear is present, it will be necessary to 
replace worn parts.

Tilt-Up Deck Adjustable Stop

When the carrier frame hinge joint is properly ad-
justed, the deck lock levers should move in and out of 
the engaged and disengaged positions freely.  All 
four (4) hitch pins used for height adjustment should 
sit flush on the washers above the deck pin bushing.  
On a level surface, if any pin is sticking up (likely the 
front pins), tighten the opposite side or loosen the 
same side to lower the pin.  Adjustments are made by 
loosening the jam nut and tightening or loosen ing the 
set screws on the Deck Mount Pivot Brack 

ets. 

 

Retighten the jam nut when the adjustment is 
complete.
