4-4.9 Disc Gang Operation. The disc gangs
may be set at an angle of 10, 15, or 20 De-
grees. The angle is adjusted by removing the
disc angle adjust pins and moving the outer
end of the disc gangs to the angle desired.
Reinstall pins to hold the disc at a desired
angle. (See Figure 3-3).
IMPORTANT
DISC GANGS ARE ASSEMBLED TO PROVIDE
CLEARANCE BETWEEN FRONT GANGS AT
10 o . IF THERE IS TOO MUCH GAP BETWEEN
GANGS AT 15 o AND 20 o , THE FRONT GANGS
CAN BE SLID IN ON THE TUBES 1".

4-5 WHEEL BEARING MAINTENANCE

Wheel bearing maintenance should be per-
formed at the beginning of every season of use.
Check the wheel bearings periodically for exces-
