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 a tire size of 23.1 / 18-26 inches.
System of turn of the K-700 tractor - 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.

Starting the engine in winter
First we have to check the condition of the machine units. To this end, it is necessary to clean the burner from carbon, wash 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:
- Connect the wire "+" to the electric motor, and connect the wire "-" to the housing.
- Open the stopper of the heating boiler and drain the spent fuel.
- Close the plug and turn off the tap.
- Prepare the water to fill the mechanism.
- Open the valve of the supercharger and the exhaust boiler.
- Open the fuel valve of the individual heating mechanism.
- For 1-2 minutes turn on the glow plug.
- To start the engine, set the switch knob for 2 seconds to the “start” position and gently move it to the “work” position.
Did you know? The K-700 tractor is equipped with its own system cold start (mechanism preheating). This feature facilitates the process of starting the engine during difficult weather conditions. You can no problem to get the technique even if the air temperature drops below 40 degrees below zero.
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 high popularity of the K-700 K-700 is due to the 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 is a big weight of the car.
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 the problem of balancing. The tractor may roll over when turning.
Did you know? If the K-700 tractor turned over, it almost always led to the death of the driver. This disadvantage of the "Kirovtsa" was eliminated in a newer version of the K-744 tractor. Specialists have been significantly enhanced and updated cabin. And the K-700 tractor release was stopped on February 1, 2002.
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.
