Appendix B - Assembly and Setup
Before You Start
❑ Read and understand the operator’s manual for your
drill. A basic understanding of how the drill works will
aid in the assembly and setup of your drill.
❑ Before attempting to assemble the drill use the
following as a check list. Having all the needed parts
and equipment readily at hand will speed up your
assembly task and will make the job as safe as
possible.
❑ Check for all major frame components.
❑ Check for fasteners and pins that were shipped with
the drill. NOTE: All hardware coming from the factory
has been installed in the location where it will be
used. If a part or fastener is temporarily removed for
assembly reasons, remember where it goes. Keep
the parts separated.
❑ If a pin, bolt or other part has been removed and you
are unsure where it is used, use the parts section of
this manual to identify it. Be sure the part gets used
in the correct location.By double checking while you
assemble, you will lessen the chance of using a bolt
incorrectly that may be needed later.
❑ Have a forklift or loader along with chains and safety
stands that are sized for the job ready for the
assembly task.
❑ Have a tractor with remote hydraulics ready to attach
to the tongue. The tongue must be anchored to a
large enough tractor to overcome the negative
tongue weight that will be present when the boxes
are attached to the frame. The hydraulics will aid in
raising and lowering the drill to align pins and bolts
during assembly.
Crushing Hazard:
Be familiar with the term NEGATIVE TONGUE WEIGHT. Be
aware of the special precautions you should take when
working with an implement that can develop Negative Tongue
Weight.
❑ Have a minimum of two people on hand while
assembling the drill.
Refer to Figure 45
1.
Read and understand the previous section titled:
BEFORE YOU START.
2. Read “Important Safety Information” on page 1,
before assembling drill.
3. Set the tongue approximately 21 inches off the
ground in a horizontal position with stable blocking
for support.
4. Raise the mainframe up, keeping the side
members horizontal. Position the mainframe over
the tongue and lower into position.
5. Secure tongue to main frame with six
1 X 2
1 ⁄
2
inch long bolts , lock washers and nuts.
6. Attach the tongue screw jack 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 hydraulic
connectors into the tractor. With tractor running at an
idle speed charge the drill hydraulic system. (Be sure
tractor has plenty of hydraulic fluid. This system
requires approximately 3.3 gallons.) When the drill
frame is raised 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 the tractor valve in the same position for at least
60 seconds after the second lift cylinder has fully
extended. The reason for the unevenness of raising
for the first time is because the 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
“Hitching Tractor to Drill” on page 13, for additional
information.
10. Attach the gauge-wheel turnbuckle to the
gauge-wheel arm on each drill and then mount the
wheel and tire.
11. Position the two drill boxes in line, end to end, with
the end chain drive sprockets outboard and
approximately 3 inches between the drill boxes. Drills
on 8 inch row spacing and narrower will have 8 inch
spacing at disks between boxes.
12. Using the tractor, back the drill main frame up to the
center of the two drill boxes . When close, position
the posts on each side of the main frame so the
face of the post mounting angles are toward the drill
frames. Attach the post
to the drill frames using
eight 5/8 X 3
1 ⁄
2
X 5 inch long U-bolts , lock
washers and nuts . With the U-bolts left
