Setup/Operation
AMADAS Pull-Type Digger-Inverters
Setup Instructions
The folding pull-type diggers are shipped in
three separate pieces: a center section, and
left and right wings. These three pieces must
be pinned together before other setup work is
done.
NOTE! Only the folding pull-type
digger-inverters require the wings to
be installed.
NOTE! Block up the digger-inverter
once the wheels are removed so the
machine does not tip over.
Preparing to Assemble
To properly align the center section for
assembly, put 2x4s under the plow shank on
the left and right side, raising the front of the
digger approximately 2”.
Preparing the Wings: On each wing, one
wheel is attached with U-bolts and the other
is clamped on with a plate and two ½” bolts.
Remove the wheel assemblies clamped on
with the ½“ bolts. These wheels will be
installed on the front toolbar later as gauge
wheels, using the ½” bolts.
WARNING
Do NOT attempt to lift the digger, as
serious injury could result. Use an
appropriate lifting means such as the
tractor to raise the machine.

Tractor Hookup
3. Hook up the hydraulic lines that control
the hitch cylinders on the digger.
WARNING
Escaping hydraulic fluid under pressure
can penetrate the skin, causing serious
injury.
Avoid the hazard by relieving pressure
before disconnecting hydraulic or other
lines. Tighten all connections before

4. Lubricate hitch (middle photo).
Search for leaks with a piece of
cardboard. Protect hands and body from
high pressure fluids.
See Chapter 1, Safety, for more
information on safe handling of
hydraulics and for instructions in the
event of a hydraulic injury.
The 8- and 12- row pull-type digger-inverters
are designed to be used with a CAT III pin
hitch mounted to the tractor draw bar.
1. Install the ball hitch provided on the
tractor draw bar. If the bar is offset, turn
it so the ball is roughly 18” from the
ground. This will insure optimum depth
control and ground clearance.
NOTE! This is a suggested height.
Actual height will vary based on your
wheels and drawbar configuration.
Lubricate before hooking up
to tractor
5. Using the tractor hydraulics, move the
cylinders to adjust the tongue height and
hook digger-inverter to the tractor.
6. Once the digger tongue is securely
hitched, install the drawbar safety latch
on the drawbar.
2. Back the tractor up to the digger-inverter.

Set Up/Operation
Tractor Hookup
7. Connect the main ¾” hydraulic hoses to
the tractor. For proper operation, it is
imperative that the pressure hose be
connected to the tractor remote forward
pressure port. The pressure hose is
marked with tape. The return must be
connected to a direct return to the
reservoir and not to the remote.
10. Using the Velcro provided, mount the
conveyor speed display unit to a clean
surface in a convenient area of the tractor
cab.
11. Connect the wire to the bottom of the
display.
Pressure hose
Connect wire
NOTE! If your tractor is not equipped
with a direct return to the tank valve, one
needs to be installed. This should be
similar to the procedure used for running
an air planter. This reduces the heat in
the hydraulic system and ensures the
conveyor cannot be reversed, which can
cause machine damage.
8. Connect the second set of 3/8” hydraulic
hoses that will be used to fold the digger
for transport.
9. Uncoil the conveyor speed sensor wire
shown in the bottom photo and route to
the cab of the tractor. Be sure to keep
the wire away from hydraulic hoses or
anything else that could damage it.

Set Up/Operation
Operation
Startup Procedure
It is important that you go through the startup
procedure and check the operation of the
digger-inverter. You will need a helper to
assist you.
1. Clear everyone from around the diggerinverter.
2. Slowly raise the hydraulic flow until 1
MPH is displayed.
10. Start the conveyor and verify the speed
setting. Lower the digger-inverter and
pull forward a few feet, then stop. The
plows should take ground immediately.
11. AMADAS recommends that you run the
digger tongue hydraulics in “float” in the
field. However, it may be necessary to
apply additional down pressure to get the
digger to take the ground at the beginning
of a row.
NOTE! If you take the tractor out of float
and apply direct ground pressure and
the digger still does not take ground, you
may need to flip the blades so that the
bevel is up. This is extremely rare and
will only be necessary in extremely hard
ground.
3. Have your helper observe the conveyor.
It should be running smoothly and
tracking in a straight path. If not, make
any adjustments needed. The top and
middle photos show the conveyor belt
correctly tracking on the conveyor shaft.
4. Have your helper observe the inverter
rotor(s). They should run smoothly
without noise or hesitation. If not, correct
as needed.
5. Slowly increase the flow until the speed
at which you will be running the tractor is
displayed (for example, if you plan to run
the tractor at 3 MPH, increase to 3 MPH).
12. Once the plows do take ground, observe
how deeply the plow is in the ground.
Typically, you will need (4”-6”) of the
shank in the ground to dig properly. If
you have less shank in the ground than
this amount, raise the front gauge
wheels. If you have more shank than this
in the ground, lengthen lower the front
gauge wheels.
6. After setting the hydraulic flow, stop the
conveyor and lower the digger-inverter
back to the ground. Shut off the tractor.
7. Observe the height of the conveyor pickup. The pickup pins on the rods should
be about three inches off the ground. If
not, adjust as needed.
8. Once these checks have been
performed, have everyone clear away
from the digger-inverter. Start the tractor
and raise the digger-inverter.
After adjusting the gauge wheels, retest
until the depth is set.
13. After proper plow depth has been set,
observe the relation of the conveyor
pickup pins to the ground. With the
conveyor height properly adjusted, the
rods should be raking the ground but not
the sub-soil. Adjust as needed.
14. Once initial start-up is completed,
proceed with the “First Run” section in
your User Manual.
9. Move to a flat, level soil area where no
peanuts are present.

Setup/Operation
AMADAS Pull-Type Digger-Inverters
Checklist for Pull-Type Digger-Inverters
 Make sure the peanut plants are
inverted.
 Inspect the tap roots. The plow
should have cut below the
peanuts but not low enough to
include the entire tap root with
fibers and dirt.
If too much of the root has been
included, lower the gauge wheels
so that the plows are raised up
higher.
 Make sure all tap roots have been
laid in a uniform line. They should
be lying within 30 degrees of
vertical.
 Make sure peanut plants are
transferring from plow to conveyor
smoothly. It may be necessary to
adjust conveyor height and/or
speed, or the vine guide rods to
ensure this.
If peanuts have been cut off,
raise the gauge wheels so the
plows cut deeper into the soil.
 The tap root cut length should be
consistent across the width of the
digger. If not, the digger is not
running level. Check the gauge
wheel position, tire pressure
(both front and rear), to correct
the problem. A bent plow or one
that is not level can also cause
this problem if only one row is
affected.
 Inspect the wheels. There
should be obvious tracks in the
soil behind the gauge wheels.
