Mower Deck Adjustment (Front-to-Rear
Levelness)
With the Rear Engine Rider on a smooth, level surface,
rotate the blade until the blade tips are at the front and rear
of the deck. Measure the distance from the blade tips to
the floor (Figure 34). The distance should be the same, or
the rear 1/8" to 1/4" lower than the front. If the rear blade
tip is higher than the front, or is more than 1/4" lower than
the front, proceed with adjustment.
1. Remove the rear hanger chains (A, Figure 34).
2. Turn each hanger pivot (B, Figure 34) the same num-
ber of rotations on the eye-bolt to raise or lower the
rear of the deck.
3. Reinstall the rear hanger chains and measure the
blade tips again.
4. Repeat Steps 1 through 3 until proper levelness is
obtained.
Rear Engine Rider Drive Components
WARNING
!
DO NOT attempt any adjustments, maintenance, service
or repairs with the engine running. STOP engine. STOP
blade. Engage parking brake. Remove key. Remove
spark plug wire from spark plug and secure away from
plug. Engine and components are HOT. Avoid serious
burns, allow all parts to cool before working on machine.
Fuel Filler Cap and vent must be closed securely to pre-
vent fuel spillage.
Service Brake / Park Brake Adjustment
Test the wheel brake on a dry concrete surface. When
properly adjusted, the Rear Engine Rider will stop within 5
feet from fastest speed. If stopping distance is more than 5
feet, the wheel brake should be adjusted as follows:
1. Follow the WARNING statement found on this page.
2. Check the fuel level in tank. If over 3/4 full, remove
tank. Refer to "Removing The Fuel Tank". If 3/4 or
less, proceed to the next step.
3. Carefully stand the Rear Engine Rider on its rear bum-
per.
4. Depress the clutch/brake pedal (A, Figure 9) all the
way down. Move and hold the park brake lever (B) in
the "ON" position and release the clutch/brake pedal to
set the park brake.
5. Measure the distance (A, Figure 35) 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, brake spring, and clutch yoke (D, E,
and F, Figure 33) are noted for reference purposes only.
6. If the measurement is less than 1/2" or greater than
3/4", loosen the two jam-nuts (A, Figure 36). Hold the
clutch/brake cable (B) to the chain case bracket.
7. 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
24
37) and the bottom of the housing.
8. After adjustment is complete, securely tighten the
cable jam-nuts.
9. Retest the wheel brake.
Mower Blade Replacement
!
Wear heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp and
can cause severe injury. DO NOT use a cutting blade
that shows signs of excessive wear or damage.
Blade Wear Limits
1. Inspect the blade frequently for signs of excessive
wear or damage (Figure 37):
(A) New blade;
(B) Wear limit (notch starts);
(C) Dangerous condition - do not use on mower!
Replace with new blade.

Blade Sharpening
1. Follow the WARNING statements found on this page.
2. Check the fuel level in the tank. If over 3/4 full, remove
the tank. Refer to "Removing The Fuel Tank". If 3/4 or
less, proceed to the next step.
3. Carefully stand the Rear Engine Rider on its rear
bumper.
4. Remove the bolts (B, Figure 38), washers (C) and
nuts (D) securing the mower blade (A) to the spindle.
5. Inspect the condition of the blade (Figure 37).
6. If the blade is in good condition, sharpen at 22 to 28
degrees (B, Figure 39). DO NOT sharpen beyond
existing cutting edge (A).
7. Check blade balance after sharpening. If necessary,
correct blade balance by grinding the heavy end of the
blade.
8. Reinstall the blade. Torque the blade mounting bolts to
the recommended range of 30 to 40 ft. lbs.
