K-700A - an improved version of the K-700 and the basic model for the creation of tractors K-701 and K-702.

There are several major differences between the K-700A and K-700 K-700 tractors. Thanks to the reinforcement of the front semi-frames, it became possible to install the motor. The base and gauge of K-700A was increased. Were updated seats. Implemented a rigid mount the front and rear axles. Radial tires were installed. Changed the location of tanks, multiplied their number, as well as increased filling volumes. Despite the fact that the modifications of the Kirovets K-701 tractor have improved technical characteristics, The base model K-700 is almost as good as it is.

Features of the device K-700

On the basic modification of the K-700 is no clutch. In the hydraulic system of the gearbox, the pressure drop is provided by the drain pedal. The manual transmission has 16 forward speeds and 8 back. The tractor has 4 transmission control modes. Four gears are hydraulic, two are neutral. Gear shift occurs without loss of power. Neutral gears are also very important. The second neutral shuts off the flow, the first neutral additionally slows down the drive shaft.

Tractor frame consists of two parts (half-frames) and is combined in the middle by a hinge mechanism. The suspension system consists of four driving wheels. Wheels should be single-ply, diskless. Wheels K-700 have tires in size of 23.1 / 18-26 inches.

K-700 tractor turning system - this is a kind of hinged-breaking mechanism. The frame consists of two double-acting hydraulic cylinders. To control the tractor's turning mechanism, a steering wheel with a gear-screw gear and a spool-type generator are used. On all the wheels of the tractor fixed drum brakes. The weight of the wheel K-700 is about 300-400 kg.

A uniform DC circuit ("-" and "+") and a 6STM-128 type radiator are fixed in the tractor. The K-700 fuel supply system consists of fine and coarse fuel filter cleaners, fuel tanks, a faucet, a high-pressure pump, an additional fuel tank, and a forced engine stop valve. The specific fuel consumption of the K-700 tractor is 266 g / kW per hour.

The Kirovts cab is not distinguished by the presence of the latest designs, but for its time it is quite a progressive and advanced model. The tractor has an impenetrable, all-steel cab with shock absorbers.The cabin is spacious and comfortable, but the car is serviced by one person. Comfortable stay in the cabin is provided by the system of heating and cooling, ventilation and heat insulation.

How to start a tractor "Kirovets" K-700

Next, you will learn how to start a Kirovets K-700 tractor. Consider the process of preparing and starting the engine, as well as features of its launch in the winter.

How to start the tractor engine

Kirovets is equipped with a four-stroke eight-cylinder engine of the YaMZ-238NM series. Of the features of the power plant, you can select a two-level scheme of air purification.

So, proceed to launch the engine K-700:

1. Remove the left fuel filler cap.
2. Fill the tank with diesel fuel.
3. Bleed supply system with hand pump for 3-4 minutes.
4. Turn on the mass switch (the test light should flash green).
5. Next, you need to pump the engine lubrication mechanism K-700 to a pressure of 0.15 MPa (1.5 kgf / cm ²). To do this, click on the starter start button.
6. Beep and transfer the switch by turning on the starter (a device that serves as a mechanical start).
7. After starting the engine, release the "start" button.

If the engine does not start, the start can be repeated after 2-3 minutes. If after repeated attempts the engine still does not work, you will have to find and fix the problem.

Starting the engine in the winter

First we have to check the serviceability of the machine units. To this end, it is necessary to clean the burner from carbon deposits, flush the tractor heating boiler and connect the supercharger motor to the circuit (12 V).

In winter, the K-700 tractor engine K-700 is started up in the following order:

1. Connect the wire "+" to the electric motor, and connect the wire "-" to the housing.
2. Open the stopper of the heating boiler and drain the spent fuel.
3. Close the plug and turn off the tap.
4. Prepare the water to fill the mechanism.
5. Open the valves of the supercharger and the exhaust boiler.
6. Open the fuel valve of the individual heating mechanism.
7. For 1-2 minutes turn on the glow plug.
8. To start the engine, set the switch knob for 2 seconds to the “start” position and gently move it to the “work” position.

Advantages and disadvantages of the K-700 K-700

Based on the characteristics of the K-700 It can be concluded about the advantages and disadvantages of the tractor. Undoubtedly, the great advantage of the K-700 tractor is the availability of spare parts, as well as the relative ease of assembly and disassembly. In this regard, the technique is very convenient in operation. In addition, the K-700 K-700’s great popularity is due to its relatively low price. The tractor is adapted to different climatic conditions. The K-700 diesel engine is powerful.Due to their reliability, these machines are still successfully operating in the agricultural fields of Ukraine and Russia.

However, the K-700 has serious structural flaws. During agricultural work, the fertile soil layer is destroyed. The reason for this - a big weight machine.

The tractor engine is supported on the front half of the frame. Traction unit is very massive. Therefore, if the car is without a trailer, this leads to a balancing problem. The tractor may roll over when turning.

Many cars are still produced on the basis of the K-700. The tractor is in demand not only in agriculture, it is also used in other industries. This once again proves the durability and reliability of this technology.
