Drive Control Adjustment
DO NOT attempt any maintenance, adjustments or service
with engine and blade running. STOP engine and blade.
Remove starter insert. Disconnect spark plug wire and
secure away from spark plug. Engine and components are
ROT. Avoid serious burns, allow sufficient time for all com-
ponents to cool.
The drive control (A, Figure 17) should engage the
transmission when the control is pushed forward, and
should disengage the transmission when pulled all the
way back.
*IMPORTANT: Before attempting to decrease drive
cable tension, perform the following test:
1) With the mower running, push the drive control for-
ward and inward to propel the mower forward.
2) Pull the drive control back to the neutral position
and immediately pull the mower backwards. You
should feel some resistance from the drive wheels.
This is normal.
3) Without engaging the drive system, push the
mower forward, then pull it backwards again. This
time there should be no resistance. If that is the
case, then drive cable adjustment is not required.
However, if resistance is still felt, then adjust the
drive cable.
Figure 17: Drive control
If the transmission does not engage or disengage,
adjustment may be performed as follows:
• If the transmission does not engage, increase drive
cable tension by loosening the jam nut (C, Figure
18} and rotating the turnbuckle (A) counter-clock-
wise one-half turn to move the ferrules (B} out from
the turnbuckle. Tighten the jam nut against the
turnbuckle. Check and repeat as needed.
If the transmission does not disengage, decrease
drive cable tension* by loosening the jam nut and
rotating the turnbuckle one-half turn clockwise to
move the ferrules in toward the turnbuckle. Tighten
the jam nut against the turnbuckle. Check and
repeat as needed.
Figure 18: Adjusting the drive cable
Caution: Incorrect adjustment can cause premature
wear and/or damage to the wheel drive components.
NOTE. Some models do not feature a jam nut.
