idler pulley. Slide bolt inward in slot and retighten nyloc nut.
c) When properly adjusted, the belt should have 1/2" of deflection with three
pounds of pressure on the belt midway between the transmission and
engine pulley.
5.2.6 Wheel drive belts and scrapers:
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.

See 3.10
5.2.10 Shifter detent adjustment:
Transmission shifter detent can be adjusted by adjusting the setscrew on the
backside of transmission located just behind the neutral start switch. Turn
setscrew in (clockwise) to hold the transmission shifter more positively in each
gear and to increase the force on the lever required to shift gears.
Turn setscrew out (counterclockwise) to decrease force on lever required to shift
gears. Factory setting is to turn setscrew all the way in then back out 1-1/2 turns.
IMPORTANT: Screwing setscrew in too far will prevent the transmission from
shifting.
