Maintenance
5. Reinstall the belt cover
securely.
6. Test the operation of the blade
brake (see "Blade Brake Control
Test" in the Operation section).
7. If the drive belt slips during op-
eration, it may be necessary to re-
locate idler (J, Figure 5-9) in the
slot provided in the mounting
bracket. With the engine stopped
and the spark plug wire discon-
nected, loosen the hardware on the
idler (J) and slide it forward to
take up slack in the belt.
8. Engage the blade drive and
measure the distance (X, Figure
5-8) between the centers of pul-
leys (K) and (L). The distance
should be 5-1/2 to 5-5/8". After
obtaining the correct dimension,
reinstall the belt cover securely
and test the operation of the blade
brake.
BLADE DRIVE CONTROL LEVER
ADJUSTMENT
Make the following adjustment if
the Blade Drive Control Lever re-
leases during operation.
1. Stop engine, wait for all parts
to stop moving, and disconnect
spark plug wire.
2. Engage the Operator Presence
Control and the Blade Drive
Control. Without releasing the
controls, look inside the cutout at
the rear of the frame and make
sure the Operator Presence
Control latches (A and B, Fig. 5-
10) are fully engaged at point (C).
If they are not fully engaged, im-
proper operation or premature
wear could result. To adjust,
loosen hex nut (D) and shorten
length of control rod (E). To avoid
over-adjusting, turn rod only 1
to 2 turns per adjustment.
3. Tighten hex nut securely after
adjusting control rod.
4. Test by releasing the Operator
Presence Control. If properly ad-
justed, the Blade Drive Control
will disengage when the Operator
Presence Control is released. Re-
adjust as necessary by repeating
Steps 2 and 3.

the wheel drive belt.
1. Stop engine, wait for all parts

tions.
4. Locate wheel drive belt (O,
Figure 5-11) and remove it from
