4.1. General information
1-beam mounted ploughs of U031 series are produced in series as 3-furrow and 4-
furrow ploughs with the possibility of mounting an attachment with 1-furrow. They are
adjusted to work on terrain slopes not exceeding 8.5and cooperate with tractors
equipped with suspension system category III (see technical characteristics –table 4)
equipped with wheel standard ballasts. User with the tractor, enabling the use of force
adjustment of the ploughing depth, should use this adjustment, which allows for saving
about 10% of fuel.

- 16 -
4.2. Construction and operation of the plough
1-beam mounted ploughs of U031 series (figure 1) are tools mounted on the tractor
three-point suspension system. Construction of the ploughs is modular, i.e. they have the
same structural elements but only differ in the number of bodies and the size of the frame.
Figure 1. 1-beam plough - general construction: 1 - main frame 2 - three-point suspension system rack, 3 -
ledger, 4 - slider, 5 - lower axle overlay 6 - quick hitch beam, 7 - transversal adjustment screw, 8 -
longitudinal adjustment screw - alignment, 9 - body saddle, 10 - handle of the coulter or skimmer,
11 - coulter foot, 12 - coulter disc, 13 - frame +1, 14 - support wheel, 15 - support, 16 - body
1-beam ploughs of U031 series are connected to a tractor with the three-point suspension
system. Suspension lower axle - quick hitch beam, is mounted in adjustable hitches of the
coupler head. The plough coupler head with three-point suspension system rack
comprises the rotary head of the plough, which is held in the proper position by a
turnbuckle. Plough main beam is connected to a stud to a slider which slides on the
ledger. The beam stud allows for rotation of the frame horizontally while width adjustment
of the first furrow is possible by sliding the slider on the ledger. Plough bodies equipped

- 17 -
with divided mouldboards (breast and wing), ploughshare with screwed chisel, scraper
bars mounted over the mouldboard and the skid are attached to the body core. Saddles of
plough bodies are attached to the plough frame with screw connections. The leg of the
plough body is connected to the saddle with screw connections, which protect the body
against overload.
Saddles fixing plough bodies on the frame allow for a step change in adjustment of
ploughing width between 30 cm - 38 cm - 45 cm. Plough is equipped with a disc coulter
mounted on the last body, other bodies are also equipped with brackets allowing for
mounting of coulters (optional equipment) or a skimmer.
1-beam plough is equipped with a support wheel fitted as standard on the last body. The
wheel saddle is mounted on the body saddle and along with the change in the ploughing
width there is also shifting of the wheel to the direction corresponding with the direction of
ploughing. Ploughs of U031 series are equipped with handles, in which there are light
devices and a triangular warning sign installed.
4.3. Equipment and fittings
The manufacturer delivers the plough for sale assembled. The manual with a spare
parts catalogue and a warranty card are delivered along with the machine by the
manufacturer.
REMEMBER
Manual with a spare parts catalogue comprise basic equipment of the plough.
1-beam plough can be optionally equipped with a skimmer or a disc coulter on
each body. Basic equipment of the machine does not involve portable light and warning
devices and a triangular sign for low-speed vehicles which are available at agricultural
equipment storehouses.
Each user of a plough shall have light and warning signs, in working order, and a
triangular sign for low-speed vehicles (sign description is available in the section
‘Transportation’). Not having them during transportation may result in an accident. For
damage incurred during an accident the user of the machine is responsible.
4.4. Preparing the tractor to work
Preparation of a tractor to cooperation with a plough consists in checking its general
efficiency in accordance with the tractor manual (pay particular attention to the proper
operation of the suspension system). It is mandatory to aggregate the plough with
recommended tractor classes equipped with standard ballasts of front axle and rear
wheels in accordance with data given in the technical characteristics of the tractor.
Hitch system
Hitch of the tractor three-point suspension system is a universal hitch adapted to connect
all machines with a typical hitch system for a given category of the suspension. Hitch
elements should be installed in such a way to enable easy adjustment. Before suspension
of the machine, ball joints of lower rods of the tractor suspension system should be in
lower position at the same height (distance between joints and the ground is minimum 200
mm). Rods set at the equal height from the ground facilitate mounting the plough on the
tractor.

Wheel spacing - adjustment
When ploughing the wheel spacing should always be measured inside
the tires.
Internal distance between the front tires must be at least equal to the
internal distance of the rear tires. It is permitted that the front wheels are
wider by approx. 10 cm. The distance between the wheels must be
symmetrical in relation to the longitudinal axle of the tractor.
The following spacing of wheels is recommended: 1200 - 1500 mm
Perfect wheel spacing = 3 x groove width + 100-150 mm
Example: groove width: 16" 3 x 380 + 150 = 1290 mm
Tire pressure
The optimum driving properties as well as the proper and long-term use can be improved
by applying the recommended tire pressure. Air pressure, particularly in rear tires of the
tractor should be equal in both wheels and in accordance with the tractor’s manual!
Figure 2. Position of the lower rods
Before suspension of the machine, lower rods of the tractor’s suspension system
shall be set in lower position at the same height (distance between joints and the ground is
minimum 200 mm). Rods set at the equal height from the ground facilitate mounting the
plough on the tractor.
Ballasts of the tractor front axle
The front of the tractor should be equipped with ballasts, in order to ensure optimal driving
properties and longitudinal balance of the tractor. Controllability factor should equal Ws 
20% i.e. front axle should be ballasted with weight equalling or higher than 20% of the total
weight of the tractor.
4.5. Preparing the plough to work
Preparation of a new 1-beam plough to operation and after storage period (e.g. after
winter) consists in checking its technical condition and most of all durability of connections
of working elements with the frame. In case of stating damage or worn elements it is
necessary to exchange them into new or regenerated ones. Otherwise, it can lead to
reduction of the tool work quality.
Caution
It is forbidden for the operator to stay between the tractor and the machine at the tractor
engine running. The plough shall be raised easily, without jerks or vibrations.
In addition, it is necessary to:
- check screw connections, in case of backlash tighten the nuts,
- check if the copying wheel, adjustment screw and adjusting spindle move easily and
without jamming, in case of stating jamming of the support wheel, it shall be uninstalled,
cleaned and lubricated,
- lubricate the plough in accordance with recommendations (see section "Lubrication
instruction").
CAUTION
All maintenance in the plough shall be performed before installing it on the tractor.
