In order to couple AT or AT-90 model to the tractor,
follow these directions:
Animal ration shredders with accessory
for tractors
Before connecting the equipment to the tractor,

observe the lifting capacity of the tractor's hydraulic
system.
Then if the tractor lift capacity is compatible with

the weight of the machine, place both on a level
ground and make sure that no one is between the
machine and the tractor.
Slowly approach the tractor from the shredder and

attach to the three points of the tractor's hydraulic
system (first the two lower arms and then the upper
arm).
Make sure that the pins are locked.

Align the shafts of the tractor power take-off and

the machine power take-off and check the distance
between the tips of the shafts.
Disconnect the two parts of the cardan (male/

female).
The measure found between the power take-off

shafts should be divided by 1.3. The value of this
division will indicate the measure A, mark the
cardan shaft with the measure A and cut the excess,
as indicated in the image (Figure 5).
In the marked position cut the excess of the male

and female cardan with a saw blade with a 24-tooth
cutting blade for steel or with cutting disc using
protective equipment.
After completing the full cut, mark the plastic

protection of the male and female cardan and
remove 3 centimeters from the plastic protection
only, cutting with a saw, leaving the cardan shaft
with the tip exposed, as shown in the image
(Figure 5).
After performing the cutting procedure, remove the

burr from the cut parts, discard the cut material, and
support the machine that is attached to the tractor
on the floor, so you have space for the cardan shaft
assembly.
Secure the protective retention chains. The ideal

operating condition is obtained with the chain
positioned radially in relation to the transmission.
Adjust the length of the chains in such a way as
to allow the articulation of the transmission in
any work, transport and maneuvering condition.
Make sure the chains do not wrap around the
transmission due to excessive size.

Before starting the work, check the rotation of the

power take-off, the rotation should not be greater
than 540 rpm, also check the inclination and if the
machine is leaning on the ground to avoid damages
in the shredder and cause the loss of warranty.
Check the minimum and maximum length of

the TDP that are required for the coupling of the
machine/tractor. In case of problems, contact the
TRAPP Technical Assistant.
Notes:
The pieces cut from the solid and tubular

parts of the cardan shall have the same
length.
Allow at least 2.5 cm on each end of the

cardan.
Instructions for

maintaining and installing the cardan guard
chain are described in the manufacturer's
manual, which is attached to the cardan.
Observe if as the machine moves the male

and female cardan shaft are approaching to
the extent of touching, if this occurs turn off
the power take-off immediately.
Disassemble the male and female cardan

shaft and re-cut to allow a clearance of at
least 1 to 2 centimeters between the ends of
the cardan shaft.
It is not recommended to work with the male

and female cardan shafts without clearance;
this may damage the power take-off shafts of
the tractor and the shredder.
To perform maneuvers, remove one of the

cardan shaft parts.
When it is at its maximum opening, the

plastic safety guards and shafts must be
overlapped by at least 1/3 of their length (LT).
When it is in its maximum closing position,

the minimum permitted distance is 1 to 2 cm.
Keep the male and female terminals of the

cardan shaft aligned.
Do not stop the tractor power take-off

suddenly, except for safety. A sudden stop
can damage the equipment transmission
system.
