1Introduction
Thank you very much for choosing the AGRETO three-point scale. You have just
purchased a robust tool for everyday use.
The AGRETO three-point scale can only be employed as a checkweigher for
internal use. It's not allowed to be used for legal transactions.
Please read this manual carefully before putting the scale to use.
As in common parlance the word 'load' is used instead of 'mass' in this user
manual.

3Intended use
The AGRETO three-point scale is a scale for weighing three-point implements
and/or their loads. It's mounted at the three-point linkage between tractor and
implement.
Tractors with Category II and III top links and lower links are suitable but only
Category II implements can be attached.
Only implements with a total weight of 6 000 kg can be attached.
The scale must be set to the exact same mounting height as the attached
implement.
The implement can only be connected to the scale via the two lower link pins
and the top link pins.
No significant push/pull forces must be transferred which means that soil tillage
implements can be attached. Seed drills with normal sowing coulters are
acceptable.
The weighing procedure can be performed during standstill or whilst driving.
Three-point scales aren't officially calibratable and therefore not authorized to
determine weights for legal transactions. The scale is meant exclusively as a
checkweigher for internal use.

Safety
4.1 Safety guidelines for the purchaser
IMPORTANT!
Make sure that every person who works with the AGRETO three-
point scale for the first time has read and understood this user
manual.
4.2 Safety guidelines for operating and assembling personnel
Appropriate equipment must be used when employing lifting
machinery for transport.
Persons who are involved with mounting removing or setting up
the three-point scale must wear safety shoes.
Persons who are involved with mounting removing or setting up
the three-point scale must wear safety gloves.

During transport the scale or pallet can slip on the vehicle.
Transport and loading personnel must be instructed to securely
attach loads.
Be aware of the risk of crushing between the three-point scale's
moving parts during mounting removing and setting up.
The scale must not be stored or used in a potentially explosive
environment.
Be careful not to trip over parts or tools that could be lying around
you.

6Getting started
6.1 Setting lower link distance
Measure the necessary horizontal distance between both lower link
mounting points on your implement (for instance a fertilizer spreader). The
standard dimension for Category II is 87 cm but in practice it's between 86
and 88 cm.
Set the required distance on your three-point scale with the adjustment
screws. Use the exterior nuts of the adjustment screws on both sides of the
three-point scale to keep the construction symmetrical.
Set the scale's width in such a way that there's a little space left between
scale and implement so that the scale isn't under tension.
When your implement has a rigid mounting axle you must completely
remove the adjustment nuts on one side of the three-point scale pull the
scale apart during mounting and push it back together again.
6.2 Setting mounting height
A correct setting of the mounting
height is of paramount
importance for your scale's
accuracy.
The horizontal and vertical top
link mounting brackets must be
in a perfect right angle relative to
each other. This will make sure
that the load's position doesn't
influence weighing accuracy.
