- 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 longitudinal
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 similar
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 re-
ducing the loads on the mounted attachment during the operation with the wide-coverage
machines, 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 mounting attachment is controlled by moving the respective hydraulic distributor
control levers from the cab as well as by the external pushbutton panel which provide the
positioning of the lower rods of the rear mounted attachment to the necessary height. The
method of adjustment of the position of the rear mounted attachment is selected by the trac-
tor driver in the manual mode by turning the handle for selecting the adjustment method on
the control board of the rear mounted attachment.
Attention!
The necessary peculiarities and method of adjustment of position of the machines
aggregated by means of mounted attachments in accordance with the peculiarities of
performing the job and agrotechnical requirements are given in the operation docu-
mentation for the machines. If such data are unavailable, obtain obligatorily the nec-
essary information from the manufacturer or seller of the machine.
The universal hydraulic system for controlling and adjusting the mounted attachments of
the tractor provides additionally the following functional capabilities for the rear mounted at-
tachment:
- correction of the speed of lifting and lowering the lower rods;
- restriction of the height of lifting the lower rods;
- selection of the necessary method of adjustment of position of the lower rods;
