5.1.19 An anti-seize compound is used on the blade drive pulley
hub, located on the engine PTO shaft (this allows for
ease of removal of the pulley).
5.1.20 Dielectric grease is used on all blade type electrical
connections to prevent corrosion and loss of contact.
5.2 ADJUSTMENTS
5.2.1 Adjusting cutting height with blade spacers.
Blades may be adjusted for cutting height by using the
four 1/4" spacers found on the blade spindle bolts
(factory setting is two above and two below). This allows
a 1" range in 1/4" increments of cutting height in any
axle position. The same number of blade spacers must be
used on all blades to achieve a level cut (two above and
two below, one above and three below, etc.).
For the best cut and discharge, place a minimum of two
spacers between the blade and spindle shaft.
For the highest quality cut, place all four spacers
between the blade and the spindle shaft.
If the mulching kit is installed, the highest quality cut
can be obtained with 3 spacers between the blade and
spindle (minimum is 1 for a good cut).
If you need to cut higher or lower than what the spacers
will allow, it will be necessary to adjust the rear axle
height and caster position. See Section 5.2.2 below.
5.2.2 Axle height and caster position.
Desired cutting height range can be obtained by adjusting
the rear axle and placing caster spacers above or below
the caster arm (See Figures 14 and 15).
It may be necessary
to readjust wheel drive and brake linkages.
To adjust rear axle:
a) Stop engine and remove spark plug wire(s).
b) Place the drive levers in the neutral lock position.
c) Remove mower deck belt shield for access to axle
adjustment belts.
d) Loosen but do not remove the two (2) axle pivot bolts
and the two (2) axle adjustment bolts (See Figure 15).
e) Place a jack under the rear center of the engine deck.
f) Raise the back end of the engine deck up enough to
remove the two (2) axle adjustment bolts.
g) With the jack, raise or lower the back end of the
engine deck so that two (2) axle adjustment bolts can
be reinstalled in desired hole location. A tapered
punch can be used to help align the holes.
h) Retighten all four (4) bolts, lower unit and remove jack.
i) Install mower deck belt shield.
j) Adjust wheel drive and brake linkages as required.
(See Sections 3.8.5 and 3.8.6).
k) Using the appropriate chart for your unit, adjust the
caster spacers as directed to match with the axle hole
selected. (See Figure 15)
