Adjustments
CAUTION
!
To avoid minor or moderate injury:
BEFORE making any adjustments, disengage PTO, wait for
blades to come to a complete stop, slowly lower ditcher to the
ground, stop tractor engine, and remove switch key. DO NOT
attempt to make adjustments while tractor is running.
Leveling And Tilt Adjustment
Refer to Figure 3-1:
1.
Manually adjust one of the two lower lift arms up or
down to level the Powered Ditcher from left to right.
2.
Manually adjust the length of the top center link to tilt
the front of the ditcher down 2 to 5 degrees.
Skid Shoe Adjustment
Refer to Figure 3-2:
Adjust skid shoe up or down as needed.
1.
Pull hairpin cotter (#3) and clevis pin (#4).
2.
Adjust adjustment bar (#2) up or down as needed
until skid shoe (#1) is at the preferred height.

If chain is loose, loosen jam nut (#6) and turn chain
adjusting bolt (#4) clockwise until excess chain slack
is removed.
4.
Tighten jam nut (#6) and recheck chain tension.

chain will have high wear.
