Transmission belt adjustment.
a) Stop engine and wait for all moving parts to stop. Remove key or spark plug
wire(s).
b) To tighten transmission belt, loosen the 3/8" nyloc nut on transmission belt
idler pulley. Slide bolt inward in slot and retighten nyloc nut.
c) When properly adjusted, the belt should have 1/2" (1.3 cm) of deflection with
three pounds of pressure on the belt midway between the transmission and
engine pulley.
Wheel drive belt pulley scrapers.
a) Stop engine and wait for all moving parts to stop. Remove key or spark plug
wire(s).
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.
Engine to mower deck belt.
a) Stop engine and wait for all moving parts to stop. Remove key or spark plug
wire(s).
b) Check the adjustment of the lower blade drive linkage located between the
bellcrank on the engine deck and assist arm on the mower deck. Lengthen or
shorten the linkage. When properly adjusted, there should be 1/16" to 1/8" (2 –
3 mm) of clearance between bell-crank and transmission output shaft when belt
is engaged. Make sure the assist arm is against the rear assist arm stop on the
deck (See Figure 21). Push the lever down to the disengaged position. The
assist arm should contact the front assist arm stop on the deck. If it does not
contact, readjust so that the bellcrank is closer to the transmission output shaft.
