Forward Speed Control Friction Adjustment - Step 7
FSC Position With Levers
1. Place the FSC in the full forward position and
pull both steering levers back; the FSC lever
should not move. If the FSC lever moves back
the friction needs to be increased.
2. With the steering levers held back, move the
FSC lever back from the forward position. With
a proper amount of friction adjusted, the FSC le-
ver should move back with a slight amount of re-
sistance (friction). If the FSC lever movement is
"stiff", the friction needs to be decreased.
3. The FSC friction is increased or decreased by
tightening or loosening the friction adjustment
nut. Loosen or tighten the nut and check the
control function until the conditions of both steps
1 and 2 are met.
PTO Belt Tension
PTO belt tension can be adjusted by lengthening or
shortening the position of the adjustment bolt on the
idler adjuster (above idler pulley). Optimum adjust-
ment will result in a 1/2 in. (1.27 cm) deflection of
the belt.
