Assembling The Drill
Refer to Figure 1 on page 15
1. Read and understand the previous section
Before You Start.
2. Read "Practice Safe Maintenance," page 4,
before assembling drill.
3. Set the tongue (1) approximately 21" off the
ground in a horizontal position with stable
blocking for support.
4. Raise the mainframe (2) up, keeping the side
members horizontal. Position the mainframe
(2) over the tongue (1) and lower into position.
5. Secure tongue (1) to main frame (2) with six
1" x 2 1/2" long bolts (3), lock washers and
nuts.
6. Attach the tongue screw jack (4) in a vertical
position and remove blocking so the unit is on
the ground.
7. Remove the safety wires from each hydraulic
cylinder rod clevis between the tires.
8. Slide the hydraulic hoses from the mainframe
through the tongue and pull them out at the
tractor end. Attach tractor male couplers to
the hydraulic hoses.
9. Hook tractor up to the tongue and plug hy-
draulic connectors into the tractor. With trac-
tor running at an idle speed charge the drill
hydraulic system. (Be sure your tractor has
plenty of hydraulic fluid. This system requires
approximately 3.3 gallons.) When your drill
frame raises for the first time, one lift cylinder
will extend fully before the other one begins to
move. Once the first cylinder is fully extended
continue to hold your tractor valve in the same
position for at least 60 seconds after the sec-
ond lift cylinder has fully extended. The rea-
son for the unevenness of raising for the first
time is because your drill is equipped with
master and slave rephasing cylinders. Raise
and lower the frame several times to be sure
there is no binding or problems with your lift
system. Refer to "Tractor Hydraulic Hookup,"
page 18, for additional information.
10. Attach the gauge-wheel turnbuckle (5) to the
gauge-wheel arm (6) on each drill and then
mount the wheel (7) and tire.
11. Position the two drill boxes in line, end to end,
with the end chain drive sprockets outboard
and approximately 3" between the drill boxes.
Drills on 8" row spacing and narrower will
have 8" spacing at disks between boxes.
12. Using the tractor, back the drill main frame up
to the center of the two drill boxes (8). When
close, position the posts (9) on each side of
the main frame so the face of the post mount-
ing angles are toward the drill frames. Attach
the post (9) to the drill frames (8) using eight
5/8 x 3 1/2 x 5" long U-bolts (10), lock washers
(11) and nuts (12). With the U-bolts (10) left
loose, slide the drill frames (8) inward so that
the lugs (13) welded to the drill frames are up
tight against the post angles. Tighten all the
nuts on the U-bolts.
13. Attach frame adjustment link (14) from the
drill frame to the pivot post using the clevis pin
(15) with hairpin cotters. Pin to pin should be
approximately 37".
14. Locate drill transport stabilizer frame (16)
against the locator stop on the box frame. Us-
ing 5/8" U-bolts (17), lock washers (18) and
nuts (19), mount stabilizer to box frame.
15. Adjust clevis end of pull bars (20) so that the
distance from the center line to center line of
pull bar pin holes is approximately 134 1/4".
16. Mount pull bars to drill transport stabilizer
frames (16) and tongue slide (21). With the
tongue slide in the back position against its
stop, adjust pull bar lengths so boxes are in
line with one another and parallel to the back
edge of the mainframe.
17. Extend the main lift cylinder (22) and place
the transport lock pins (23) in the transport
position through the holes in the mainframe
axle side tube.
18. Fold the drill making sure that the tongue slide
(21) moves smoothly up the tongue. When
drill boxes are almost folding in, stop and ad-
just the post-frame adjustment links on each
box so that the tang (24) on each drill trans-
port stabilizer frame lines up with the nest (25)
on the front of the main frame. Fold drill com-
pletely closed.
19. With tongue slide (21) forward on the tongue
and drill folded completely, position the pull
bar lock pin (26) across the top of the tongue
slide. Adjust the transport lock bolt (27) on top
