Mower Leveling - Toro 74241 Operator's Manual

1. Check the electrolyte level; refer to Checking
Electrolyte Level, page 44.
2. Remove the filler caps from the battery and connect a
3 to 4 amp battery charger to the battery posts. Charge
the battery at a rate of 4 amperes or less for 4 hours
(12 volts). Do not overcharge the battery. Install the
filler caps after the battery is fully charged.
Warning
Charging battery produces gasses that can
explode and cause serious injury.
Keep cigarettes, sparks and flames away from
battery.
Make sure the ignition switch is off.
Ventilate when charging or using battery in an
enclosed space.

Mower Leveling

1. Position mower on a flat surface. Stop the engine, set
the parking brake, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Check tire pressure of all four (4) tires. If needed,
adjust to 13 psi (90 kPa)
3. Set anti-scalp rollers to top holes or remove them
completely for this adjustment.
4. Raise the deck to the transport position and take all
force off of the two large deck lift springs by loosening
nut in front of each spring (Fig. 48).
5. Place two 1-1/2 (38 mm) thick blocks under rear left
and right lower edge of mower. Place one 2-1/4
(57 mm) block under front center lower edge of
mower. Lower mower to the 2 (51 mm) height-of-cut
position (Fig. 48).

6. Loosen four (4) top chain bolts in slots. Check the
length of the rod/swivel assemblies. Distance from
outside of rear swivel to outside of front swivel should
be 19-17/32 (496 mm) (Fig. 49). Make sure that all
four swivels move freely in holes.
7. If measurement is not 19-17/32 (496 mm) on each
side, adjust by turning nuts on either side of front
swivels.
8. Lift up on four (4) top chain attachment bolts, in the
slots, to take slack out of chains and tighten flange
lock nuts. (Deck is still supported by two rear and one
front blocks under mower.)
9. If bolts contact the end of slots, shorten or lengthen
rod/swivel assemblies as required, for extra clearance,
adjust each side same amount.
Note: When properly adjusted, the front blade tip will be
slightly lower than the rear blade tip. See Checking for
Bent Blades on page 30 to measure.

10. Recheck that blocks just fit just under the mower and
that tension on all four chains is approximately equal.
Tighten chain attachment bolts securely.
11. Measure height of cut. This can be checked with the
same procedure as Checking for Bent Blades on
page 30.
12. Install anti-scalp rollers for proper height-of-cut and
tighten securely.
Compression Spring Adjustment
1. Raise deck lift lever to the transport position, (Fig. 48).
2. Springs are compressed so the distance between the
two large washers should be 10-1/4 (260 mm)
(Fig. 49).
