If your snow thrower will not discharge
snow, check the control cable adjustment. If
it is correct, then check the condition of the

aged. If it is damaged, replace it (see To
Replace Belts on this page).
TRACTION DRIVE BELT
The traction drive belt (see second figure
on this page) has constant spring pressure
and does not require adjustment.
• Replace the traction drive belt if it is slip­
ping (see To Replace Belts paragraph on
