KIROVETS K-744R1, K-744R2, K-744R3, K-744R4 tractors

Electrical equipment system
has the voltage of 24 V and is single-wire, the minus terminals
are connected with the tractor
“frame”. Two storage batteries and an alternating current
generator with integral voltage regulator serve as power supplies. Power use
rs’ electrical
circuits are protected against short-circuits by fuse blocks. On the tractors, there is the
possibility of connection to power supply with the voltage of 12 V. The plug socket is located
under the cover in the right bottom part of the instrument panel support, near the
“12V” label.
The diagram of electrical equipment is given in Appendixes 10, 10A, 10B, 10C.
The tractor is provided with a hydraulic system and a three-point mounted implement, which
serves for connection of mounted and semi-mounted agricultural machines and implements to
the tractor, for their regulation in the working position and their transfer into the transportation
position. A 5-section hydraulic distributor with remote cable-operated control is installed on the
tractors in the hydraulic system of working equipment, out of them four sections (levers 2, 3, 4,
5) are designed for connection to external hydraulic lines. All 5 sections of the hydraulic
distributor have flow-rate regulators, the handles of four flow-rate regulators are brought into the
cabin through openings in the floor; when the handle is rotated in the clockwise/anticlockwise
direction the flow-rate through the section decreases/increases respectively.
In order to increase pressure
at the outlet from the 2nd and
3rd pairs of hydraulic system
outlets from two gate valves of
the
hydraulic
distributor
(control handles 2 and 3), the
automatic return switch is
excluded.
The installation of handles into
the “NEUTRAL” position from
the service positions shall be
carried out manually.
