1 Introduction
1.1 General
Before starting to use the plough, you are strongly recommended to carefully read through the
manual and safety instructions.
The user must be familiar with the VPX folding snow plough in order to guarantee safe usage.
1.2 Description of VPX snow plough
The VPX folding snow plough’s wings can be adjusted ±38°. This means that the plough can be
used both as a diagonal blade and as a folding snow plough.
The plough is intended to be connected to an existing attachment for agricultural tractors, loaders
and compact tractors. The TREJON OPTIMAL VPX folding snow plough can be equipped with
quick-coupling attachments for most tractors. The plough is equipped with a diagonal valve as
standard. This makes it possible to operate each wing independently or both wings together
diagonally.
The folding plough can be set in 3 different positions, depending on the type of work to be
performed. Y-CONFIGURATION for pavements, S-POINTED CONFIGURATION for conventional
road ploughing, street junctions and other areas where you can collect up and remove the snow,
D-DIAGONAL CONFIGURATION for clearing snow from car parks, streets, etc.
The VPX cutting blade works as standard with a 15° positive cutting angle. This provides an
efficient and clean cut, even at high speeds.

1.5 Attachment with floating mode function
The floating mode attachment is movable for vertical pivoting and twisting (horizontal) (see figures
1, 2 and 3 below for a description of the movement capacity).
It is important to position the floating mode attachment so that it can move freely up and down.
Lower the plough to the ground. Lower the attachment to its end position (see Figure 2) and then
lift the attachment approximately 70-80 mm. In this position (floating mode), the plough is able to
follow the surface optimally.

1.6 Attachment
The type of attachment / hook (1) for the machinery’s loader (3) or suspension must always be
specified when ordering a VPX folding snow plough. It is important to use the correct tightening
torque: M20 (420 Nm) and M16 (215 Nm) for all bolts (4) when installing the attachment / hook (1)
on the plough’s floating bracket (2).
Figure 5
Warning!
Loose or poorly tightened bolts can cause the plough to come loose and cause
material damage and/or personal injury!
1.7 Blank attachment
There are many different machines. In those cases where the Trejon does NOT have a ready-
made attachment, customers can weld these onto a blank plate themselves. There is a ready-
made kit for this, art. no. 84005 –see Figure 6. Customers can weld attachment hooks for the
load carrier themselves. For mounting on a VPX plough, read section 1.6.
Warning!
It is the person who welds/manufactures the attachment who is responsible for
any incorrectly performed welding/manufacturing that may result in future injuries
or accidents.

1.9 Support plates
The VPX folding snow plough is equipped with two support plates, which can be adjusted using a
crank (size NV19) to the desired position. Remove the ring pin (1) and lock plate (2) from the
adjustment screw (3) before carrying out height adjustment –see Figure 8. Use the crank (4) for
height adjustment 360° = 5 mm –see Figure 9. Restore the lock plate (2) and cotter pin (1) to lock
the adjustment screw (3) following height adjustment –see Figure 10.
Figure 8 Figure 9 Figure 10
When ploughing for the first time or when the roadway is soft, it can be an advantage to raise the
folding snow plough (X ≥ 0) (see Figure 11). This is done to prevent unnecessary wear on the
cutting blade and to avoid cutting up gravel.
After ploughing a few times or once the roadway has frozen and become hard, you are
recommended lower the folding plough by adjusting the support plates upwards to the same level
(X = 0) as the cutting edge (see Figure 12).
Better ploughing results are achieved once this has been done.
NOTE!
Always replace damaged or worn support plates in time –Trejon art. no. 980002. If
the plate comes loose, the support leg will also be damaged. This is NOT covered
by any warranty.
NOTE!
Make sure that the support plates are the same height on both sides.
Damage due to incorrect adjustment is NOT covered by any warranty.

1.10 Cutting edge
The VPX plough is equipped with the following cutting edges (A, B, C –see Figure 13.). The
cutting edges are sprung (F) and reversible. The outer cutting edges (a) have a bent edge which
reduces the risk of becoming stuck in obstacles.
The sprung cutting edges reduce damage in the event of a collision. Standard cutting edges can
be reversed by switching from left to right.
It is important to check wear and tear on the cutting edges daily. There are many factors that affect
this. These factors include ploughing speed, substrate, cutting angle, support plates and
adjustment of the floating mode. It is therefore important to maintain the distance W ≥ 10 mm
between the lower edge of the cutting edges (1) and the lower edge of the steel holder (2) (see
Figure 14).
When the wear is significant and the distance W≤ 10 mm (see Figure 15), it is time to move all the
cutting edges downwards (see Figure 16). When this position is also worn, the cutting edges (B)
are turned or shifted (from left to right and vice versa); this applies to the cutting edges with bent
ends (A).
It is important that the cutting edges do not protrude downwards more than 60 mm, i.e. W max. =
60 mm.

C
Two extra centre cutting edges (C) are supplied with each VPX folding snow plough. They are
located on the right-hand side of the centre frame –(see Figure 17)
You are recommended to order new centre cutting edges, art. no. 85708, as soon as the last pair
has been installed on the plough.
NOTE!
Trejon Optimal cutting edges are made of the highest quality steel to provide a
low overall cost. The cutting edges are wear components and their service life
CANNOT be determined. The cutting edges are NOT covered by any warranty.
NOTE!
Damage due to the use of other cutting edges is NOT covered by any warranty.
NOTE!
Replace the cutting edges when they have become worn.
1.11 Cutting angle –adjustment
The default cutting angle is 15° (Z = 420 mm) –see Figure 18. In general, cutting angles only need to
be adjusted after the springs have been replaced –see section 1.12.
Dimension Z –see Figure 18 –can be used as a control measure. By tightening the nut (M) in the
upper part of the spring rod (P), the cutting angle is smaller –for cutting angle 0°, Z = 390 mm.
Loosening the nut (M) makes the angle larger.

1.12 Springs –pretensioning of cutting edges –adjustment
NOTE!
If the pretension of the cutting edges is too high, there is a risk of accidents and of
the device breaking. Sprung cutting edges are a safety arrangement, and they are
intended to make ploughing safe. If any of the springs has become deformed or broken off,
we recommend that all the springs on the blade be replaced, art. no. 200595.
The default pretension, i.e. spring Y dimension, is 330 mm –see Figure 19.
To increase the pretension, adjust Y dimension as follows:
1) Loosen nuts M1 and M2 in the lower part of the spring –see Figure 19
2) Tighten nut M1 upwards two turns at a time and test operate. Repeat until the tension is
just right –see Figure 20
3) Tighten nut M2 against nut M1 to lock the spring –see Figure 21
NOTE!
If the pretension of the cutting edge is too low, the cutting edge constantly gives
way, the ploughing results are poor, the plough jumps and causes unnecessary
noise.
To decrease the pretension, adjust Y dimension as follows:
4) Loosen nuts M1 and M2 in the lower part of the spring –see Figure 21
5) Tighten nut M2 downwards –see Figure 20
6) Tighten nut M1 downwards two turns at a time and test operate. Repeat until the tension is
just right –see Figure 20
7) Tighten the lower nut M2 against nut M1 to lock the spring –see Figure 19
