5.2.4 Wheel drive belts and scrapers.
a) If wheel traction appears to be slipping, drive lever
rods may be touching bottom of neutral lock/park brake
latch slot. To adjust, refer to directions in Section
3.8.5.
NOTE: There are three (3) adjustment holes for the wheel
drive spring tension bolt (Refer to Section 5.2.15).
b) Be sure mud and grass scraper, on each side, is
adjusted properly and centered in the pulley grooves.
The pointed part of the scraper should be centered and
as deep in the pulley groove as possible without
rubbing at any point.
5.2.5 Engine to cutter deck belt.
a) Stop engine and remove spark plug wire(s).
b) For proper adjustment of lower blade drive linkage,
lengthen or shorten linkage. When properly adjusted,
there should be 1/16" to 1/8" of clearance between
bell-crank and transmission output shaft when belt is
engaged.
c) Check belt guides under rear engine and front mower
deck to see that they are properly set. (See Section
5.2.7).
d) Belt must be tight enough to not slip during heavy
loads while cutting grass. Overtensioning will
reduce belt and spindle bearing life. To adjust belt
tension, loosen the 5/16" whizlock nut on turnbuckle
and rotate the turnbuckle; rotate turnbuckle toward
rear of mower to tighten, and toward front of mower
to loosen belt tension (See Figure 16).
Check belt tension after the first hour of operation
and at least twice during the first 24 hours of
operation. Adjust as necessary.
