BRAKE ADJUSTMENT:
LOWER ROD - The
brake assembly has been set at the factory.
However, they may periodically need
adjustment. As a rule of thumb, the bottom
bend of the lower brake rod (3:14) should be
3/8” lower than the center of the pivot boss hole
in the brake arm (3:5). If adjustment is needed,
simply thread the 5/16 wing nut (3:20) in or out
to obtain specified adjustment.
•
UPPER ROD - To adjust brake handles for
comfortable grip, remove bridge pin and fender
washer securing top of upper brake rod to
brake lever assembly. Slide end of rod out of
brake handle, turn rod in or out of rod fitting end
replace rod into brake handle, check, readjust
as needed; when set to desired position,
replace washer and bridge pin. NOTE: After
adjustment, be sure mower stops completely
and uniformly when brake handles are
squeezed.
•
BLADE BELT ADJUSTMENT:
We
recommend checking belt tension after one
hour and then after the next 10 hours of
operation, then re-check after each 50 hours of
use. To check tension, first engage cutting
blades. Place a belt tensioning gauge in the
center of the belt span. The gauge should read
10 pounds pressure with a 3/8" deflection. To
adjust belt tension:
125KAW & 13BS:
•
Disengage cutting blades. Loosen the jam nut
(4b:29) securing lower blade engaging rod
against lower ball joint (4b:31). Turn rod
clockwise to increase tension, counterclockwise
to decrease. Engage cutting blades, recheck,
readjust as needed. Also noted that there is a
second hole in the brake idler arm that can be
used if needed.
