: Keep in mind that any maintenance or adjust-
ment described in this manual is the owner’s
sole responsibility.
WARNING: Never remove guards or make
adjustments while machine and/or tractor engine
is running.
WARNING: After making adjustments, check the
machine very carefully for possible loose parts
or bolts. Make sure aIl guards, shields, and doors
are in place and properly secured before starting
the tractor engine
CAUTION: Never perform work on the Rotary
Corn attachment without first Iowering it to the
ground and applying tractor brakes.

machine, safely raise machine with blocs (see
safety section).
GROUND CLEARANCE ADJUSTMENT
In order to prevent an early wear of the machine or a
mechanical break down, it is important to adjust the
ground clearance. For corn harvest, it is recommended
to adjust the ground clearance to 12 inches (30 cm).
This is the actual distance between the ground and the
saw blade. This adjustment is done through the Forage
Harvester’s hydraulic system.
