of bearings which enable its movement and tilting. On the suspension axle there is a rack
with top connecting openings mounted. Coupler head with three-point suspension system
is equipped with two adjustment screws which enable width adjustment of the first furrow -
transversal adjustment (pos.7 Fig. 1) and changes in the angle setting the main beam -
longitudinal adjustment (pos.6 Fig. 1). Leg handles are connected with an auxiliary beam
of ploughing width adjustment, allowing to change the width of the groove from 30 cm to
50 cm on all bodies at the same time using a turnbuckle or a hydraulic actuator (pos.6).
The plough body leg is mounted in the frame handle by pivots and suspension springs
which protect them against overload. As a standard, plough bodies are equipped with split
bolt mouldboards and ploughshares with interchangeable chisels. In addition, plough
bodies can be equipped with a strip chipper, which is designed to cut the top layer of soil
and throw it onto the bottom of the groove and thus better covering plant residues. Skid of
the last body is equipped with a screwed heel.
Copying wheel setting the ploughing depth is mounted in the handle of the third
body and along with the change in the furrow width there is also shifting of the wheel to the
direction corresponding with the direction of ploughing. Ploughs of U068 series are
equipped with handles, in which there are light devices and a triangular warning sign
installed.
Optionally, the plough bodies can be equipped with disc skimmers mounted on the
body beam with the use of clamp grips, allowing for easy adjustment.
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 disc skimmer. 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. 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.
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 screws and adjusting spindle move easily and
without jamming, in case of stating jamming of the supporting 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.
4.6. Aggregation of the plough with a tractor
When connecting the plough to a tractor, it is necessary to make sure that:
- tractor lower rods are below plough suspension studs,
- connecting points of the tractor and plough are in the same category,
- in the transportation and working positions, lower and upper connecting points of the
plough with a tractor three-point suspension system are set in a vertical plane,
- during operation side stops of the lower rods allow for small clearance of the plough to
the sides, but during transportation side clearance of rods must be eliminated noting that
there is no collision between the tool and the surface of rear wheels and construction
elements of the tractor.
When mounting the plough on the tractor, perform following activities:
- disassemble a tool latch bar from lower rods of the tractor three-point suspension
system,
- drive to the machine frame close enough with the tractor,
- turn off the tractor engine, remove the key from the ignition switch and pull
handbrake,
- install tractor lower rods onto the suspension axle studs and secure them with typical
cotter pins,
- using a pivot, link the upper connector of the tractor with the plough frame rack and
secure with a typical cotter pin,
