Adjusting the Mower Belt
Tension
Adjust the mower belt tension as follows:
• After the first 8 operating hours.
• After the first 25 operating hours.
• After every 50 operating hours.
Check the belt tension after the first 8 operating hours
and 25 operating hours thereafter. Check the belt
tension after every 50 operating hours.
Important: The blade brake needs to be adjusted
when the belt tension or the brake linkage is
adjusted.
Important: The belt must be tight enough to not
slip during heavy loads while cutting grass. Over
tensioning the belt will reduce the bearing life of
the belt and the spindle.
1. Disengage the blade control (PTO) lever and set the
parking brakes.
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. Loosen the locknut on the turnbuckle (Figure 36).
4. Rotate the turnbuckle toward the rear of the
mower to increase the tension on the belt. Rotate
the turnbuckle toward the front of the mower to
decrease the tension on the belt (Figure 36).
Note: The eyebolt threads on both ends of the
turnbuckle should be engaged a minimum of
5/16 inch (8 mm).

Maintenance
Servicing the Cutting Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement, you
may want to keep extra blades on hand.
A worn or damaged blade can break, and a
piece of the blade could be thrown into the
operator's or bystander's area, resulting in
serious personal injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control bail and set the parking brake. Turn the ignition
key to off. Remove the key and disconnect the spark
plug wire(s) from the spark plug(s).
Inspecting the Blades
Inspect the blades every 8 hours.
1. Inspect the cutting edges (Figure 38). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.

2. Curved Area
2. Inspect the blades, especially the curved area
(Figure 38). If you notice any damage, wear, or
a slot forming in this area (item 3 in Figure 38),
immediately install a new blade.
