How To Adjust The Brake / Parking Brake
Test the wheel brake on a dry concrete surface. When
properly adjusted, the unit will stop within 5 feet from fastest
speed. If stopping distance is more than 5 feet, adjustment
is required.
Manual Drive Models:
1. Set the parking brake. Refer to “How To Set The Parking
Brake”.
2. Measure the distance (A, Figure 39) between the end of
the clutch/brake cable (B) and the bottom of the housing
(C). The measurement should be no less than 1/2” and
no greater than 3/4”.
NOTE: The cotter pin and brake spring (D and E, Figure 39)
are noted for reference purposes only.

3. If the measurement is less than 1/2” or greater than 3/4”,
loosen the two jam-nuts (A, Figure 40). Hold the clutch/
brake cable (B) to the chain case bracket.
4. Adjust the cable up or down using the jam-nuts to obtain
a distance of 1/2” to 3/4” between the end of the clutch/
brake cable (adjustment shown in inset of Figure 39)
and the bottom of the housing.
5. After adjustment is complete, securely tighten the cable
jam-nuts.

How To Adjust Mower Blade Belt Tension
1. Remove the mower deck cover. Refer to “How To
Remove The Deck Cover”.
2. With the unit off and the mower blade disengaged (refer
to “How To Engage The Mower Blade”), measure the
body of the blade engage spring (A, Figure 41).
3. Engage the mower blade, and measure the extended
blade spring (B). It should measure 3/8” to 1/2” longer
than the unextended spring measurement in Step 2.
4. If adjustment is needed, disengage the mower blade,
loosen the rear jam nut (C) securing the PTO cable
housing (D), and adjust the cable housing in or out using
the front jam nut (E).
5. Repeat Steps 3 and 4 until the desired measurement
is reached. Make sure to tighten the rear jam nut when
adjustment is complete.
NOTE: Check to be sure there is slack in the PTO cable
(F) when the mower blade is disengaged. This is essen-
tial for correct operation of the blade brake. If there is no
slack, lessen the cable tension until slack is obtained.
6. Replace the deck cover.
