Adjusting Blade Brake

Before each use, check blade brake for proper
operation.
The blade brake must be adjusted to stop the blade(s)
when the blade control (PTO) lever is disengaged.
1. Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
and turn the machine "OFF".
2. To adjust the blade brake, engage the blade
control (PTO) lever.
3. Loosen nut at the brake spring so pad rubs
against pulley. Then tighten nut until pad just
clears the pulley (Fig. 36).
4. Disengage blade control (PTO) lever. Brake
rod(s) must be loose (Fig. 36).
5. Both conditions must be achieved for proper
adjustment.

Tire Pressure

Service Interval/Specification
Maintain the air pressure in the front and rear tires as
specified. Check the pressure at the valve stem after
every 50 operating hours or monthly, whichever
occurs first (Fig. 37). Check the tires when they are
cold to get the most accurate pressure reading.
Pressure: 15 psi (103 kPa) rear tires
25–30 psi (172–207 kPa) castor tires

Cleaning the Cooling System

Service Interval/Specification
Before each use, check and clean engine cooling
system. Remove any build–up of grass, dirt or other
debris from the cylinder and cylinder head cooling
fins, air intake screen on flywheel end, and
carburetor–governor levers and linkage. This will
help insure adequate cooling and correct engine speed
and will reduce the possibility of overheating and
mechanical damage to the engine.
