6.27. Clamp the fingers on the return-to-neutral mech-

anism so that they hold the tab on the control
quadrant to the tab on the indexing plate.
See Figure 6.27.

NOTE:

This will effectively lock the return-to-

neutral mechanism positively into neutral.

6.28. Rotate the steering link rod to lengthen or

shorten it until the lap bar is centered in the
notch at the neutral position.

6.29. Tighten the jam nuts on the steering link rod to

lock-in the adjustment.

6.30. Remove the clamp.

6.31. Repeat the procedure on the second IHT if nec-

essary.

6.32. Lower the Z-Force to the ground and test-run it

in a safe area.

6.33. With the lap bars pushed forward or pulled back

an equal amount, the Z-Force mower should
track straight.

6.34. After the steering link rods are adjusted,

set the

lap bar stop bolts

.

6.35. Loosen the jam nuts on both lap bar stop bolts.

6.36. With the engine turned off, push each lap bar

gently forward until it reaches the end of the
travel allowed by the return-to-neutral mecha-
nism. See Figure 6.36.

6.37. If there is a difference in the travel of the two lap

bars, adjust the stop bolt on the lap bar with the
least travel so that it just contacts steering pivot
bracket as the lap bar reaches the end of its
travel.

6.38. Adjust the second lap bar so that it matches the

first.

NOTE:

If the mower does not track straight after

these adjustments are complete, particularly on
a slight grade, internal wear of the transmission
on the side that it tends to track toward may be
the cause.

NOTE:

For the first two years of residential use,

or one year of commercial use, the IHTs are
within their warranty period, and will be replaced
as complete units if a

warrantable failure

occurs. Beyond the warranty period, complete
service procedures for the Hydro-Gear 31-2400
IHT are outlined in Hydro-Gear publication: BLN-
51134.

NOTE:

Replacement IHTs are shipped dry

because of ICC regulations. Prior to installation,
they must be filled with 79 fl.oz. or 20W50 motor
oil. When properly filled, the level should reach
a point 1 7/8” down from the TOP of the trans-
mission housing.
