Information on repair and maintenance of tractors Kirovets cars electronically
The Kirovets tractor is a symbol of power, reliability, and the engineering expertise of the Leningrad (now St. Petersburg) Tractor Plant. For decades, these machines have been the backbone of agriculture, construction, and municipal services across Russia and beyond. They are valued for their high durability, ease of maintenance, and ability to operate in the harshest conditions—from scorching steppes to northern cold.
Modern Kirovets tractors are no longer just tractors, but fully-fledged high-tech machines featuring electronic control systems, powerful diesel engines, and next-generation hydraulic systems. Their electrical circuits, transmissions, and comfort systems have reached the level of the world’s best counterparts, while maintaining the legendary endurance and simplicity of design.
History of the Kirovets Tractor
The history of Kirovets tractors begins in the post-war years. In 1962, the first K-700 rolled off the assembly line of the Leningrad Tractor Plant, marking the start of an entire family of heavy wheel tractors. The machine quickly gained popularity thanks to its unique power and ability to work on any type of soil.
- K-700 (1962–1975) — the base model equipped with a 215 hp YaMZ-238 diesel engine. It featured a mechanical transmission and minimal electronics.
- K-700A / K-701 (1975–1990) — an improved design with a better gearbox, reinforced axles, and a new-generation cab.
- K-744 (1995–2008) — a fully redesigned generation intended for work with modern agricultural implements. It received YaMZ-850 and Cummins engines.
- Kirovets K-9000 (since 2008) — the most powerful tractor in the lineup, equipped with Mercedes-Benz OM 457 and OM 502 engines delivering up to 516 hp.
- Kirovets K-7M (since 2019) - the newest series with an upgraded cab, improved electronics, hydraulics, and digital control components.

Kirovets Tractor Repair Manual
Proper maintenance requires having the original Kirovets tractor repair manual in PDF format on hand. These documents include detailed electrical diagrams, hydraulic schematics, torque tables, and parts lists with item numbers.
The manual is especially useful for:
- diagnosing engine and electrical system faults;
- replacing belts, pumps, and filters;
- servicing the transmission and driveshaft joints;
- repairing the hydraulic system;
- checking the alternator, starter, fuses, and control units.
The “Electrical Schematics” section includes all circuits-from the starting system to lighting and signaling. For newer models (K-7M), diagrams for onboard computer connections, pressure sensors, CAN bus, and climate control systems are included.
The maintenance and wiring diagrams help resolve issues such as:
- engine not starting or starter malfunction;
- hydraulic overheating or low pressure;
- headlights or dashboard lighting not working;
- relay and fuse failures;
- fuel or oil leaks;
- unstable battery charging system;
- malfunctions in the implement control system;
- loss of power or unstable operation under load.
Kirovets tractors have become not only part of the history of domestic engineering but a key element of the agricultural industry. Their rugged construction, repairability, and durability have allowed the plant to compete with foreign brands and maintain leadership in the heavy machinery market.
Kirovets is machinery built to work for years. And having detailed electrical diagrams and service manuals allows mechanics to quickly eliminate any malfunctions, preserving the legendary reliability of these tractors at the highest level.
