Shorten Driveline
Refer to Figure 1-9:
Be sure to check driveline collapsed length first. If
required, shorten driveline.

Continue with “Check Driveline Maximum Length”.
Check Driveline Maximum Length
Refer to Figure 1-10:
The driveline maximum allowable length must, when fully
extended, have a minimum overlap of profile tubes by not
less than 1/2 the free length with both inner and outer
profile tubes being of equal length.

3.
Slowly engage tractor hydraulic 3-point control lever
to lower cutter while checking for sufficient drawbar
clearance. Move drawbar ahead, aside, or remove if
required.

Refer to Figure 1-11:
4.
With PTO off, raise implement fully up to make the
following checks below. If driveline exceeds any of
the limits listed, set tractor 3-point lift limiter at a
height that will keep the driveline within its lift limits
and to avoid premature driveline breakdown.
