Maintenance
FOR SAFETY REASONS, EACH MAINTE-
NANCE OPERATION MUST BE PER-
FORMED WITH TRACTOR PTO DISEN-
GAGED, THE CUTTER LOWERED COM-
PLETELY TO THE GROUND OR FOLDED
WITH THE TRANSPORT LOCK CHAIN IN-
STALLED AND THE TRACTOR ENGINE
SHUT OFF WITH IGNITION KEY RE-
MOVED.
Proper servicing and adjustment is key to the long
life of any machine. With careful and systematic
inspection of the cutter you can avoid costly main-
tenance, time and repair.
1.
Perform all services outlined in the section on
periodic maintenance.
2. Check jackshaft coupling to ensure that key is
in place and bolts are fully tightened.
3. Check that all split-taper bushings are secure.
4. Check that all cutting unit tie rods are secure
and properly adjusted.
CAUTION
a. Set unit on a flat surface, with the centerline
of front and rear jackshafts the same height
above ground level.
b. Adjust front tie rods so that the distance be-
tween the cutting unit frame rear cross-tube
and the rear jackshaft is the same at both
ends.
c. Adjust rear tie rods so that the distance be-
tween the reel side plates and the edge of
the adjacent reel strut is 10-5/16” (26 cm).
NOTE:
A simple way to check to see if the tie rods are
properly adjusted is to pull a string across back
side of the units. The sting should touch the
backs of the frames equally—See illustration
below.
5. Check that all safety guards are intact and
securely fastened.
6. Jack up the carriage frame. Remove the wheel
hubs. Clean, inspect and re-pack the bearings
with good quality general purpose grease (such
as BP Energrease MK 11). Adjust the bearings
so that there is no end play but the wheel turns
freely.
NOTE: Do not over tightened bearings.
