D. Altering the length of both braces and upper rod for the transport position of
the machine.
- clearance: at least 300 mm;
- sufficient safe distance between the members of the tractor and those of the machine
excluding the contact of the machine members with the tractor (the clearance shall be at
least 100 mm).
Е. Altering the length of both braces
- when transporting the machine (with the top position of the hitch linkage), the limit rods
shall be shortened to the maximum extent within the existing adjustment for limiting the
swinging of the machine during the motion to avoid the damage of the tractor members in
possible emergencies;
- when operating the mounted and semi-mounted soil cultivating machines with passive
tools intended for overall tillage (share and chisel ploughs, stubble-breaking ploughs, deep
tillers and other machines), it is necessary to ensure the free motion (swinging) of the
lower rod in the horizontal plane to the distance of 125 mm to each side from the longitudi-
nal plane of the tractor unblocking the limit rods; no limitation of the grasp width by means
of the rods is allowed;
- when operating agricultural machines (except for ploughs, deep tillers and other simi-
lar machines for overall tillage of the soil with passive tools), ensure a partial blocking to
limit the swinging of the lower rods in the horizontal plane to not more than 20 mm.
Attention!
Failure to follow the recommendations for adjusting the limit rods and braces can
cause the rupture of the rods and support brackets or other breakages.
С. Adjusting the brace
During the operation, the braces are connected usually with the lower rods through the
holes in the brace forks.
To improve the transversal contour following (cultivators, sowing machines, etc.) and
reducing the loads on the hitch linkage during the operation with the wide-coverage ma-
chines, it is necessary to ensure the free movement of one lower rod in the vertical plane
relatively to another rod. To do this, it is necessary to adjust the braces in such a way that
a free movement of one lower rod in the vertical plane relatively to another rod would be
achieved. Such adjustment is ensured by connecting the braces through the slots.
The rear hitch linkage is controlled by moving the respective hydraulic distributor control
levers from the cab as well as by the external pushbutton panel which provide the position-
ing of the lower rods of the rear hitch linkage to the necessary height.
Attention!
The necessary peculiarities and method of adjustment of position of the machines ag-
gregated by means of mounted attachments in accordance with the peculiarities of per-
forming the job and agrotechnical requirements are given in the operation documentation
for the machines. If such data are unavailable, obtain obligatorily the necessary informa-
tion from the manufacturer or seller of the machine.
