3. The tractor's top lift link should be extended or
retracted until the chain case is vertical when
lowered to the normal operating position. The
universal drive shaft must have an equal offset in
each joint (See Figure 4-3.) As an example, if the
front joint is offset 6 degrees the rear joint must also
have a 6 degree offset. Should the rear joint be offset
4 degrees or 8 degrees the cutter head will not run at
a constant speed and will vibrate excessively.
Operating the ditcher in this condition will cause drive
shaft, shear bolt and chain failures.
