Important: The blade brake needs to be adjusted

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).
