DANGER!
You may be severely injured or killed by being crushed between
the hitch and drill. Do not stand or place any part of your body
between drill and moving hitch. Stop tractor engine and set park
brake before installing the hitch pins.
1. Place hitch extension (1) between top hitch plates on
drill. Bolt hitch extension in place as shown in Figure
1-3 using two 1-by-5 1/2-inch bolts (2), lock washers
(3) and hex nuts (4).

move transport lock pins from vertical tubes above
tires. Place transport lock pins in storage hole next to
stabilizer cylinder. See Figure 1-4.

3. Position center pivot hitch in front of drill so quick-hitch
links on hitch are in line with lower hitch pins on drill.
Hydraulically retract transport-lift cylinders to position
quick-hitch links slightly lower than drill hitch pins.
4. Position quick-hitch handles to locking position as
shown in Figure 1-5. This will allow drill hitch pins to
snap into quick-hitch links and secure drill to hitch.

5. Back center pivot hitch up to drill until hitch pins con-
tact quick hitch. Hydraulically raise hitch just until drill
hitch pins are secure inside quick-hitch links. Do not
raise drill any higher than necessary.
6. Attach slotted level-link bar (1) to top hitch extension
on drill. Use 1-by-3 3/4-inch pin (2) and bushing (3) to
pin level-link bar to drill. Secure pin with clip provided
(4). See Figure 1-6.
