3-POINT LINKAGE (TUZ)
Construction of the suspension system assumes that
the tractor and the machine are meant to work
together as set. Functionality of the set is influenced
by the way the upper and lower links on
hangers are regulated.
To make optimal regulation of the BT harrow easier,
in case the tractor has three linking points, the upper
link should be linked to the highest point.
Lower links should be regulated to be set on the
same height
Regulation of the hangers must allow lifting the
machine to the proper height, so that it could be
transported safely.
Regardless of whether the lower links have the
chains attached or not,
the telescopic stretcher bar or other stabilization
system used should be regulated in a way enabling
the BT harrow mounted to the tractor to move
slightly from side to side, without swaying too much
during transportation.
FRONT AXLE LOAD

OPERATOR’S MANUAL: DISC ARROWS HGR | HGR - H

PREPARATION OF THE TRACTOR
To verify the total stability so that the minimum weight of front weights can be calculated, what leads to
making sure that the front axle load is at least 20% of the mass of the tractor alone, the formula presented
below can be used:
−Calculating the real load of front axle formula:
−Calculating real total mass formula:
−Calculating real rear axle load formula:

STARTING WORK
UPPER SUSPENTION POINTS
The machine can be connected with the tractor`s
upper link by the permanent slots (OS) or movable
slots (OP) that allow the harrow to lift up slightly when
stumbling upon large disturbing items during working
on rocky fields.
Using movable slots can help eliminating unwanted
machine`s vibrations and swaying.
Movable slots are also recommended for mounting
wide (4m) disk harrows.
When the upper link is connected to the movable slot
of the hanger, the link must be untightened so that
the bolt is unloaded when the harrow is lowered
down.
Note: Movable slots are available on all machines
except HGR 15, HGR 17 and HGR 20 which have 3
slots (OS).
When regulating the tractor`s couplers and changing the geometry of
harrow`s fastening stay cautious! There is a risk of body squeeze!
There is a risk of body squeeze or body parts being cut off by unwanted
and accidental machine and tractor disconnecting! Make sure that no
outsiders are present in the machine`s area during its regulation.
DEPTH REGULATION
Correctly mounted, levelled and adjusted harrow
during cultivation should move evenly behind the
tractor and maintain such position so that the area is
cultivated onto the same depth.
To keep uniform working depth of the harrow, level
the harrow:
•In transverse direction by shortening or
lengthening of the right hanger.
•In lengthwise direction by shortening or
lengthening of the upper connector.
Adjustment of working depth of disks assembly is
done using adjustment located at the coupler
between main frame and rear roller, as the harrow is
lifted by the roller.
To set working depth of the machine by changing
adjustment setting on the frame:
•Lift the machine on the tractor's three-point
linkage lift.
•Remove pins (P) secured with cotters which limit
movements of rear roller arms and the frame of
the machine against each other on the
adjustment gauge (R).

OPERATOR’S MANUAL: DISC ARROWS HGR | HGR - H
15
STARTING WORK
•Turn the actuators (S) on using the tractor`s hydraulic
system (the actuators are placed on each arm- there
are two or three of them, depending on the machine`s
width). Lower or lift the rear shaft towards the main
frame of the disk harrow. If the machine is not
equipped with actuators, it should be lowered or lifted
using TUZ suspension system to change the working
depth settings.
•Secure the shaft`s arms again by putting the pins in the
slots. Make sure that you are using slots placed most
closely to the arms position. Remember! Perform the
described action on both sides of the machine,
making sure that pins are placed equally on both left
and right regulation scales
•Regulate the coupler between the tractor and the disk
harrow so that the harrow is positioned in parallel to the
ground (in working position).
•In case of working resistance exceeding tractor`s
traction output, the working depth should be lowered.
NOTE: It is explicitly important to remember about setting the
regulating pins equally on both sides of the machine.
Disobeying hereby provision will lead to machine`s fast
damage.
If there are problems with pulling the pins out or putting them
back in, the harrow should be unloaded by lifting it up and
letting it fall freely.
DISKS SECTIONS
Both disc sections are mounted to the main frame
using holders allowing for horizontal adjustment of the
discs' working position (three or four holders at each
disc’s section according to working width of the
machine). Thanks to such solution it is also possible to
position the sections against each other in a way
other than factory-set, if the operator finds it is
required by specific soil conditions on a particular lot
(soil type, moisture or amount of harvest residues) to
achieve soil mixture as thorough as possible or to
cover harvest residues.
The horizontal adjustment causes no change in disc
spacing in relation to each other within one section,
or no change in angle of their operation.
ATTENTION! Switching of both disc sections to side
positions (outermost) will cause a slight increase in the
machine's working width and may cause the
machine to leave strips of inaccurate cultivated soil
between rows of discs, operation of which is not
followed by the other section (as a rule each strip of
the soil under cultivation should be “mixed” by two
rows of discs at the same time within a single
passage).

OPERATOR’S MANUAL: DISC ARROWS HGR | HGR - H
16
STARTING WORK
DISK SECTIONS
Para alterar a posição da secção de discos:
•Secure the tractor against rolling and lower the
harrow onto the ground.
•Remove locking screws (R1) on holders of a given
section.
•Loosen nuts of adjustment screws (R2) on holders
of a given section.
•Slightly lift the harrow on the tractor's hydraulic
system and slide the disks section into a desired
position.
•Re-tighten screws R2 and install screws R1.
NOTE: It is recommended that the above procedure related to
change in position of disks section is carried out by a
specialized service.
NOTE: When adjusting disks and whole sections there is a risk
of crushing, cutting, truncation caused by failure to follow
safety regulations!
Never remove adjustment screws as this may cause falling of
the whole machine sub-assembly and thus result in crushing of
the operator's body or it part, including potentially lethal
injuries!
!
SIDE SCREENS
HGR 15 | HGR 17 | HGR 20
Side screens, located at both sections, are intended
to prevent formation of any unevenness at the edge
of the field under cultivation. Properly set screens
disable pouring of the soil onto the strip near the strip
under cultivation and thus provide protection
against formation of undesired unevenness as
bumps or holes on the line between strips of soil
under cultivation.
Each screen can be adjusted for the distance from
the last one on a given disk section.
To change horizontal position of the screen:
•Remove fastening bolt (S).
•Slide screen holder (U) out of the aggregate
frame to fix it in its optimal position.
•Remount the screen holder (U) using bolt (S).
ATTENTION! The above procedure should be carried
out for both screens, from the left and the right side
of the machine

OPERATOR’S MANUAL: DISC ARROWS HGR | HGR - H
17
STARTING WORK
NOTE: When performing horizontal adjustment of the side
screen remember to secure it against falling and sliding from
the disks section frame after adjustment screws are loosened!
If caution is not exercised there is a risk of crushing a part of
the operator's body!
The screen also has vertical position adjustment as
including soil conditions, working depth and driving
speed, the soil thrown by the last disk before the
screen can be released onto a variable height.
To adjust the height of the side screen, proceed as
follows:
•Unscrew (S1, S2 eS3) bolts and adjust the screen
(E) using the existing holes in the support (U).
•Once this is done, retighten the screws.
ATTENTION: The above procedure should be carried out for
both screens, from the left and the right side of the machine.
SIDE SCREENS
HGR 25| HGR 27 | HGR 30 | HGR 40 | HGR 40H | HGR 50H | HGR 60H
In a similar way here too, it is possible to adjust the
horizontal position and the vertical position of the side
screens.
To change horizontal position of the screen:
•Loosen nuts (N) and screws (S).
•Move holder (RP) of the side screen to a desired
position.
•Tighten screws (S) and nuts (N).
To adjust the screen height:
•Unlock and remove pin (P) and insert it in a
desired hole on the gauge (R)
•Secure the pin (P).
