4. NOTE:
It is possible to install the engine to mower deck drive belt P/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 (3) 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 8 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 mower deck to a height
which will allow measurements to be taken from the surface to the tops of the two outer
mower deck cutter blades P/N 8688.
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 measure ment from level
surface to the bottom of the cutter blade tip, rotate blade and check measurement on
opposite end of cutter blade. Tip to tip measurement on the same cutter blade should not
vary more than 1 /8th of an inch. Maintain measurement taken and v erify against the right
outer cutter blade. 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 as viewed from operator's position.
Measure from surface to the bottom of the cutter blade tip, at the rear of the mower deck.
Using the nut on the single front L-rod, loosen or tighten as required to place the mower deck
approximately 1 /8th of an inch higher in the rear than the front of the deck.
6. Re-check belt routing and alignment, start engine, burnish in electric blade clutch using at
least (5) engagements at 3/4 to full throttle settings. Each engagement should last
approximately (5) seconds.
NOTE:
The completed adjustment places the mower deck in a position which wi ll produce a
quality cut. Ground speed, grass conditions, types of grass, tire pressures, dull or bent
blades and loose belts are just some of the factors which will cause poor cut quality.
