Belt Adjustment
The 260 Series Gear Drive Tractor uses a sliding idler
pulley to adjust the drive belt tension. Proper tension
will provide ½” (12.700 mm) belt deflection under light
pressure. To check the belt adjustment:
1. Remove the center access plate located between
the fender and the hood stand.
2. Loosen the belt guide and check the belt tension,
which should be ½” (12.700 mm) belt deflection
under light pressure (Figure 209).

3. Loosen the bolt and nut holding the idler pulley to
the bracket. Adjust the pulley as necessary to
achieve the ½” (12.700 mm) deflection (Figure
210).
