Preparing the plough
The plough is usually delivered for sale in a ready
-
to
-
operate condition. Due to the
limitations of the means of transport, it is also possible to deliver it in a partially
disassembled condition. Prior to operation check the technical condition of the plough, in
particular that of the working parts and screw connections.
4.2.
Selection of the hitching bar
In order to obtain a stable width of the first furrow
-
slice,
the theoretical intersection line of the lower bars of the
tractor’s hitch should be located in a distance equal to 1/3
of the tractor’s axle base, behind the front axle. Failure to
do this may cause the plough to “slew”. In such a case, a
hitching bar of a different length must be used.
4.3.
Hitching the plough to the tractor
The lower bars of the three
-
point hitch should be at the same height, spaced
correspondingly to the spacing of the lower hitches of the plough. When hitching the
plough to the tractor, the implements should be placed on a hard and level surface. When
hitching the two pieces
of machinery together, complete the following steps:
•
suspend the hitching bar on the lower bars of the three
-
point hitch and secure with
cotter pins,
•
switch the tractor hydraulic system into adjustment position,
•
reverse carefully, suspend the implement on
the bar and secure with pins,
•
connect the tractor upper fastener (during operation of the implement, the hitch
point of the upper fastener on the implement must be located higher than the
attachment point of this fastener on the tractor),
•
check the operation of plough lifting, lowering and the hydraulic system.
Connection of the upper fastener
•
Oval (longitudinal) holes allow for better longitudinal ploughing of the terrain. Use
