SECTION 4 -- LUBRICATION AND MAINTENANCE
4--55
OPERATION 41
AUTOMATIC PICK--UP HITCH
Place a load on the pick-up hitch hook. A trailer or
implement is suggested. Ensure that the hitch will
latch and unlatch satisfactorily. If adjustment is
necessary, remove the load from the hitch before
adjusting the latch.
Drop Down Hitch
Loosen the locknut (3) and remove the clevis bolt (4).
Slide the lift rod from the hitch and rotate to adjust the
length. Refit the lift rod to the hitch and temporarily
replace the clevis bolt. Repeat the procedure on the
the opposite lift rod ensuring an equal amount of
adjustment is applied.
Test hitch operation to ensure that both lift rods
support the hitch equally at the start of raise. Check
the hitch will latch and unlatch correctly, then tighten
the lift rod locknuts and clevis bolts.
When fully raised ensure that the hydraulic system
relief valve does not blow or that the hitch lift rods are
not under tension. Both these symptoms indicate
that the hitch lift rods are too short.
If the tension on the hitch release cable requires
adjustment, loosen the locknut (2). Adjust the
tension by re--positioning the nut (1) on the cable
adjuster. After re--setting, check for satisfactory
operation and re--tighten the locknut.
