The difference between the Kirovets K-700 and other tractors

The Kirovets K700 machine is equipped with a “cold start” system, which allows you to start the tractor engine even at a temperature of -40 degrees Celsius. This is achieved due to the preheating mechanism provided in this tractor model.

Kirovets K700 allows the use of units:

  • Mounted.
  • Semi-mounted.
  • Grippers.

Starting the Kirovets K-700 engine

  1. Before starting the engine, the gear shift knob must be in neutral position.
  2. Next, you need to unscrew the filler cap of the left fuel tank.
  3. Pour diesel fuel into the tank.
  4. Bleed the supply system using a hand pump (3-4 minutes).
  5. Turn on the ground switch.
  6. Bleed the motor lubrication device to a pressure of 0.15 MPa. This is done by starting the starter.
  7. Signal and switch the switch by activating the starter (mechanical starting device).
  8. After starting the engine, release the “start” button.
  9. If unsuccessful, starting the engine can be repeated after 2-3 minutes.

25 years ahead

In 1968, the K-700 tractor received a gold medal at an exhibition of agricultural machines in Germany, and in 1969 it was recognized as the world's most powerful agricultural wheeled tractor at the 40th Paris Salon-Exhibition of Tractors and Agricultural Machines. Indeed, the power, labor productivity, reliability, ease of operation and repair of the Kirovets met the world requirements of that time. Moreover, experts claim that this machine is at least 25-30 years ahead of its European counterparts.

The tractor frame consists of front and rear articulated semi-frames. The front frame is equipped with a water-cooled engine, an oil system (engine oil cooler and gearbox), air filters and an engine pre-heating system, as well as a pedestal, cabin, fuel tank and cladding parts. The front axle is attached to the bottom. A linkage mechanism with lifting hydraulic cylinders, a coupling and a single-speed power take-off shaft gearbox are installed on the rear semi-frame of the tractor. The rear axle is attached to the rear semi-frame from below using stepladders.

The K-700 tractor is equipped with a four-stroke eight-cylinder diesel engine YaMZ-238NB with a power of 220 hp. with a turbocharger and a two-stage air purification system. The engine cylinders are cast together with the upper part of the crankcase and are arranged in two rows in the form of a Latin letter V with a camber angle of 90°. This arrangement is due to the desire to reduce the length of the engine, which contributes to a more rational layout and a reduction in its overall weight. The reciprocating motion of the pistons is transmitted to the crankshaft mounted in a block on five supports. Each cylinder has a gas distribution system with two valves: intake and exhaust. Air is supplied to the cylinders by a turbocharger under excess pressure. As a result of turbocharging, an increased dose of fuel is burned, and, consequently, engine power increases. The thick-walled piston crown houses an open toroidal combustion chamber that provides maximum air swirl.

The K-700 tractor does not have a clutch. Instead there is a drain pedal (pressure drop in the gearbox hydraulic system). The gearbox is mechanical, with constant mesh gears, hydraulically controlled four clutches and mechanically controlled gear clutches. All gears are straight-cut. Number of gears (hydraulic) - 4 (plus 2 neutral), 4 modes (mechanical), high-low switching. As a result, the number of speeds is 16 and, accordingly, 8 rear. The box is designed to change gears without loss of power (due to friction clutches). Modes are switched by moving gears, as in any manual transmission. The speeds change when the spool is switched (by redirecting the hydraulic oil flow), the 2nd neutral turns off the hydraulic flow, the 1st neutral, in addition to turning off the hydraulic flow, mechanically brakes the drive shaft (shaft with clutches) in the gearbox, like a hand brake.

Thus, a gearbox with 16 speeds in 4 ranges, 2 drive axles, a mechanical transmission, and hydraulic control of switching within modes ensured the efficiency of technological, working and transport modes. The hydraulic turning system and articulated frame optimized the layout and increased the maneuverability and maneuverability of the tractor. New traction qualities (5 tons on a hook) and a speed of up to 10 km/h when plowing increased labor productivity in agricultural and transport operations by 2-3 times and reduced the agrotechnical time required for agricultural work by 2 times.

Working conditions of the K-700 tractor driver

The designers paid special attention to the working conditions of the tractor driver. The tractor cabin was made all-metal, sealed, equipped with a ventilation and heating system and sprung seats. In addition, there was a first aid kit, rear-view mirrors, windshield wipers, sun visors, interior lighting, turn signal lights, side lights and brake lights. A box for a tank with drinking water was welded to the rear wall of the cabin, and a panel with control instruments, toggle switches and signal lamps was installed on the front wall. All basic operations for assembling a tractor with various implements could be performed by the tractor driver himself.

Models created on the basis of the K-700 tractor

In 1975, the Kirov Plant began serial production of the K-700A tractors with an 8-cylinder YaMZ-238NDZ engine (235 hp) and K-701 with a 12-cylinder YaMZ-240BM2 engine (300 hp). The only difference between these models was the engine, but both were very different from the base K-700. So, they had different wheels (not unified with the wheels of the K-700 tractor), not one, but two fuel tanks (side), which merged into a single unit with the front wings of the tractor, there were no springs. This option began to be used in other sectors of the national economy of the USSR. For installation on the rear semi-frame of the K-700A and K-701 tractors, various equipment was developed: loading P-4, P-4/85, stacking, etc.

On the basis of the next model, K-703, with a reversible control post, the LT-163 timber stacker (after the LT-195 modernization), the ML-56 timber skidding machine, the LB-30 gradedozer, the PF-1 front-end loader, and the DM- universal road machine were created. 15, etc. To perform reclamation and other work, a trencher was developed on the basis of the Kirovets tractor.

Seeing the great demand for the Kirovets in other sectors of the national economy, the Kirov Plant produced a wide variety of equipment based on this tractor model: tractors, bulldozers, loaders, vibratory rollers, snow blowers, mobile welding units, etc. Demand for K-700 series machines and its modernization does not decrease to this day.
