Checking the Hood Screen
and Radiator for Debris
Service Interval: Before each use or daily Check a the hood
screen and radiator more frequently in
extremely dusty and dirty conditions.
To prevent the engine from overheating, keep the hood
screen and radiator clean. Check the screen and radiator for
buildup of grass, dust, and debris, and if necessary, clean any
debris off these parts; refer to
Radiator for Debris (page
Cleaning the Hood Screen and
Radiator
Service Interval: Every 200 hours—Inspect the
cooling-system hoses.
Every 1,500 hours—Replace any moving hoses.
Every 1,500 hours—Flush and replace the
cooling-system fluid.
Note: If the PTO shuts off due to high engine temperature,
first check the hood screen and radiator for an excessive
buildup of debris. Clean the system before operating the
machine. Do not shut off the engine immediately; allow the
engine to cool by running it without a load.
Clean the radiator as follows:
1. Remove the hood.
2. Working from the fan side of the radiator, blow with
low pressure, 172 kPa (25 psi), compressed air (do not
use water). Repeat this step from the front of the
radiator and again from the fan side.
3. After the radiator is thoroughly cleaned, clean out any
debris that may have collected in the channel at the
radiator base.
4. Clean the screen and install the hood onto the machine.

Brake Maintenance

Adjusting the Service Brakes

Service Interval: After the first 10 hours
After the first 50 hours
Every 50 hours
Adjust the service brakes when there is more than 25 mm (1
inch) of free travel of the brake pedals or when the brakes do
not work effectively. Free travel is the distance that the brake
pedal moves before you feel braking resistance.
After the first 10 hours of operation, you should need to
adjust the brakes only after considerable use thereafter. You
can perform these periodic adjustments where the brake cable
connects to the bottom of the brake pedals. When the cable
is no longer adjustable, you can adjust the star nut on the
inside of the brake drum to move the brake shoes outward.
However, you will need to adjust the brake cables again to
compensate for this adjustment.
1. Release the lock arm from the right-brake pedal so that
both pedals operate independent of each other.
2. To reduce the free travel of the brake pedals, loosening
the front jam nuts at the threaded end of the brake
cable (Figure 74).
1. Rear jam nuts
3. Rotate the rear jam nuts to move the cable rearward
until the brake pedals have 13 mm to 25 mm (1/2 to 1
inch) of free travel.
4. Tighten the front jam nuts after the free travel of the
brake pedals are properly adjusted.
