4. Note: It is possible to install the engine to mower deck drive belt CP/N
6111) at this time; however, our engine manufacturers have suggested that this
belt be installed after the engine has been fully serviced per manufacturers'
suggestions and allowed to operate at 1/2 to 3/4 throttle settings for
approximately C3) minutes. This will place the initial start up of the engine
in a no load situation and allow complete engine lubrication.
Adjustment:
1. Install engine to mower deck drive belt (P/N 6111).
2. Check and adjust tire pressures.
Front 19 to 21 psi; Rear a to 12 psi.
Tires may have been over inflated for shipping purposes.
3. Place the mower on a level surface. Using the lift handle, raise the mowerdeck to
a height which will allow measurements to be taken from the surfaceto the tops
of the two outer mower deck cutter blades CP/N 6321).
4. Align both outer mower deck cutter blades to obtain a side to side measurement.
Starting with the left blade as viewed from operator's position,secure
measurement from level surface to the bottom of the cutter blade tip rotate
blade and check measurement on opposite end of cutter blade. Tip totip
measurement on the same cutter blade should not vary morethan l/8th of an inch.
Maintain measurement taken and verify against the right outer cutterblade. If
adjustment is required, loosen or tighten the nuts on the two rear L—rods.
5. Align both outer mower deck cutter blades front to rear asviewed fromoperator's
position. Measure from surface to the bottom of the cutterblade tip, at the
rear of the mower deck. Using the nut on the singlefront L-rod, loosen or
tighten as required to place the mower deck at anattitude of approximately
l/8th of an inch higher in the rear than thefront of the deck.
£. Recheck belt routing and alignment, start engine, burnish in electric blade
clutch using at least C5) engagements at 3/4 to full throttle settings. Each
engagement should last approximately C5) seconds.
Note: The completed adjustment places the mower deck in an attitude or
position which will produce a quality cut. Ground speed, grassconditions,
types of grass, tire pressures, dull or bent blades and loose belts arejust
some of the factors which will cause poor cut quality.
