Adjusting the Tension for 48in Mower
Decks
Important:
The belt must be tight enough to not slip
during heavy loads while cutting grass. Over tensioning
the belt will reduce the spindle bearing life, the belt life
and the idler pulley life.
Important:
The brake needs to be adjusted when the
belt tension or the brake linkage is adjusted.
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 54).
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 54).
Note:
The proper mower belt tension is 10-15 lbf.
(44-67 N) with the belt deflected 1/2 inch (13 mm)
halfway between the pulleys (Figure 53).
