Foreword
We thank you for your confidence towards DION-Ag Inc. agricultural equipment. We have prepared this setup
guide with care & attention and have designed it as an essential tool that will allow you to prepare the machine
for delivery adequately and safely.
Carefully read this guide in order to familiarize yourself with the adjustment procedures and operation, before
delivering this machine. Keep in mind, this machine has been designed and tested to perform in most conditions.
However, its performance is tightly linked to the maintenance it receives.
This guide has been prepared with the latest available information at the time of publishing. The company reserves
the right to make any changes without prior notice.
Safety
The Safety section of your Operator’s manual is intended to point out some of the basic safety situations which
may be encountered during normal operation and maintenance of your Forage Harvester, and to suggest possible
ways of dealing with those situations.
This section is NOT a replacement for other safety practices featured in other sections of this guide.
The safety of the operator is one of the main concerns in designing and developing a new Forage Harvester.
Designers build in as many safety features as possible. However, every year accidents may occur which could have
been avoided by a few seconds thought and a more careful approach to handling farm machinery and implements.
Read and implement the safety instructions detailed within and share them with other operators.
Work safely. Always block the harvester wheels and turn off the tractor before working on the harvester.

least 8500 lbs. and forks at least
42” long.
There are 2 slots on the harvester
frame for the forks. One
perpendicular to the axle and one
at a 45° angle.
Approach the harvester
perpendicular to the frame and
axle mount.
Advance the forklift through the
2 fork slots until the forks are
sufficiently under the pick up
point.
Fork pick up point under
the harvester frame.

WARNING: Approaching the
harvester without minding
the forks may result in severe
damage to the kernel processor.
Assistance is required when
setting up to lift the harvester.
Have a guide present to ensure
no contact is made between the
forks and the processor
assembly.
NEVER place the harvester
directly on the ground.
Ensure the harvester is properly
supported on blocks with a
minimum height of 6” (15cm) at
3 points as described.
1 point under the left axle.
1 point under the right header
attachment location.
1 point at the tongue, supported
by a block of wood OR the jack
stand which the harvester is
equipped with.

Axle and Wheel Installation
Check all parts have been delivered.
Wheels, axles, axle mounting bolts.
Delivery includes 2 left wheels and 2
right wheels.
Install the wheels on the axles.
Note: Only ‘TerraTrac’ are directional
tires!!
They must be installed in “trailed"
mode as shown.
Position the axles flat on wooden
blocks and remove the wheel bolts.
Place the wheels onto the axles
ensuring the air valves face upwards.
Use a tire lifting tool OR two people to
place the tire onto the axle.
Install the 6 bolts by hand.
Tighten the 6 bolts to 120lb-ft (163
N.m.). Wheel torque should be check
after the first hour and every 20h for
the first 60h.

Axle Mounting (Right Side)
Remove the nuts and lock
washers on the right axle.
Install the axle extension and the
light pole (right side).
Install the 8 lock washers and
tighten all 8 nuts.
Lift the harvester with a forklift.
Advance the harvester to the
right side tandem and slide the
tube into the hole of the
harvester.
The axle should slide in easier
when the harvester is lifted to
approximately 18” between the
ground and the frame.
The longer portion of the axle
should be towards the rear of the
harvester.
Use the lock pin and cotter pin in
the toolbox to fix the axle to 1 of
the 3 desired position (3 holes in
the long tube).
Typically, the axle should be
installed with no holes exposed
(axle tube assembly as close to
the harvester as possible).
Approach the harvester perpendicular.
Ensure the forks do not make contact
with the kernel processor.
Longer portion of the axle towards the rear.
The tube must be
installed so that
the metal plates
face upwards.

right side, approach the harvester
perpendicularly.
Place the left side of the harvester
safely on blocks.
Remove the nuts and lock washers
from the axle assembly.
Lift the tandem wheel assembly.
Ensure the longer portion of the
assembly faces the front of the
harvester.

If the header is one of the following, no extension
is required:
Hay pick up F46 –2.13m (84”)
3 Row corn head F64 –2.3m (90”)
If the header is one of the following, an extension
must be used:
Hay pick up F71 –2.74m (108”)
4 Row corn head F61 –3m (120”)
Removing the extension arm to make the short
base:
Unscrew the 4 bolts securing the light to the
extension.
Install the light onto the main support using the
same hardware.
Ensure the wires are not pinched during the
installation.
Affix the cable to the assembly using cable ties.
Without extension.
With extension.
Install the light onto
the main support.

Attach the extension to the pole with the
provided bolts.
The cable is looped within the frame section for
transport. Cut it free.
Pass the wire of the harvester through the light
pole and guide it through the oblong hole.
Prior to fastening the cable, ensure to leave
sufficient slack in the cable for when the light is
the raised position.
Loop excess wire and fasten with cable ties and
ensure wires do net get pinched.
Use this locking pin when the extension arm is in
the up or down position.
Ensure the cable is not pinched when the
extension arm is lowered to the down position.

Do NOT lift the assembly using the handling
arm.
This assembly is heavy. Use a forklift equipped
with 8’ forks.
Prepare wood blocks to ensure the header is not
placed directly onto the ground.
NEVER stand under or around an unsecured
machine!
Attach the chain securely to the handling arm
and the forks of the forklift.
Provide enough slack in the chain so that when
you reverse with the forklift, the head can be
lowered slowly to the ground.
Before reversing, start with the chain at ~45°
angle as shown. Once the head pivots, lower
the forks slowly as you continue to reverse.
Once flat on the ground, unbolt and remove the
metal skid and the handling arm.

Transport Plates
Spout
DANGER: Removal of this spout bracket must be done prior to operating any of the
hydraulic systems. Failure to remove this bracket before operating the hydraulics could
result in injury or death.
In certain transport scenarios, the spout must be lowered in order to fit transport enclosures. This is achieved by
utilizing a temporary support bracket.
The spout is heavy. Support the
spout safely with a lifting strap and
use an overhead chain block or
another lifting implement to lift.
Be mindful not to pinch hydraulic
lines or wiring. Do not use a chain
to lift the spout.
Remove and retain the 4 bolts and
nuts (2 each side).
The spout may have shifted during
transport. The spout may need to
be jostled in order to remove the
bolts.
Discard the yellow curved support
bracket.
Slowly lift the spout with the lifting
implement. If it does not pivot,
loosen the remaining 2 bolts more.
Do not remove them.
While lifting, the spout pivot
should rotate and fall into place as
shown in the photo.
Once the pivot is fully seated, the
bolts and nuts can be reinstalled.
Tighten all 4 bolts and nuts (2 on
each side).
This bolt will need to be loosened
on both sides of the spout in order
for it to pivot. Do not remove it.
Remove and retain the
4 bolts and nuts. 2 from
each yellow bracket.

15
Tongue
The drawbar lock plate
(yellow) is meant to act as a
lock during transport.
Remove the hardware
affixing it to the frame and
discard the hardware and
the locking plate.
Setup Instructions
Refer to the operator's manual for additional preparation information.
Tractor connections
The hydraulic lines are heavy. Do not route electrical lines
through the same rung as the hydraulic lines.
Route the hydraulic lines, through the handle, between the
1st and 2nd rung.
Route the hydraulic lines, through the handle, between the
2nd and 3rd rung.
Tractor setup (see operator’s manual)
Scorpion 300/2430:
Connect the “P” line to an SCV with continuous flow set at 10l/min (2.5gpm)
Connect the “T” line to a ‘Motor Return’port on the tractor. Connecting to an SCV might trap
pressure or increase return line pressure and cause hydraulic malfunction.
********************************
Scorpion 350:
Always ensure the tractor is OFF before making connections
Ensure correct couplers are equipped
To prevent damage to the hydraulic system
Connections should be made in order of: D, T, LS, P
Disconnect in this order: P, LS, T, D
