General information
The K-701 tractor is a general-purpose agricultural machine.
K-701 is equipped with a four-stroke 12-cylinder diesel engine with a V-shaped arrangement of cylinders YaMZ-240BM.
Characteristics of the K-701 tractor: frame design
Two half-frames connected by a hinge device represent the tractor frame. Due to the presence of vertical and horizontal hinges, there is the possibility of relative rotation of the semi-frames. The rotation of the frames around the horizontal hinge is limited to 16 degrees, and around the vertical hinge - 35. This achieves high maneuverability and good adhesion of all wheels to the soil, no matter how uneven it is. Both frames are welded.
Engine
The K-701 tractor is equipped with a reliable, durable and very productive 12-cylinder engine of the YaMZ-240 type. The engine installation systems and the diesel engine itself are located on the front tractor half frame using three supports (one front and two rear). Starting engine starter. The automatic control system of the YaMZ-240BM diesel fan is designed to create the best thermal performance mode for the engine, which is controlled by a thermostat and a shutter. They are located in front of the radiator.
The operation of the engine is ensured by the following systems: air purification system, fuel system and cooling system.
The tractor also has a pre-heating system. It provides preparation of the diesel engine for starting at temperatures below -10 ° C and maintains a sufficiently high temperature of the liquid in the cooling system in cases where the engine is not working. The operation of the system is ensured by the presence of a boiler, burner, supercharger and pipelines through which coolant flows. The heating and cooling system are connected in parallel.
Tractor transmission
A mechanical transmission is installed on the K-700, K-701 tractor, which is a combination of mechanisms, which includes the following elements:
- Semi-rigid coupling. This element carries out the transfer of torque from the motor to the gearbox, reduces engine loads during sudden overloads, reduces the values of torsional vibrations and drives hydraulic pumps of the steering control system and the attachment. Also, if necessary, it allows you to disconnect the engine from the transmission.
- Transmission. The K-701 tractor (photo presented) is equipped with a mechanical, multi-stage gearbox, which has permanent gears. Hydraulically controlled. The presence of clutches allows you to perform gear shifting with a continuous flow of power within the mode. Installed box on shock absorbers.
- Bridges. Both axles are leading, but the rear axle can be disabled. Their fastening is carried out on half frames. Bridges are interchangeable. The parking brake is located on the front axle.
- Cardan transmission. Serves to create a four-wheel drive tractor.
Wheelless wheels with low pressure tires and treads providing good tractor patency. The diameters of all wheels are equal to each other.
Control systems
Turn control is carried out using hydraulics, which includes two hydraulic cylinders and a control valve. When fluid is supplied to the hydraulic cylinders, they displace half frames relative to each other.
The rotation control system includes the following components: a hydraulic distributor with a worm gear, a pump, a steering column, a flow regulator, hydraulic cylinders, a tracking device, a hydraulic tank, a radiator and hydraulic drives.
Tractor service brakes are block type brakes. The brake includes a drum, caliper and brake pads. The drum is fixed on the hub of the final drive, the caliper is located on the axle cover.
Tractor brakes are pneumatically driven by a pedal located in the cab.
The parking brake is located on the front axle, shoe-disk type. Its main purpose is to hold the tractor when it is parked at a slope of up to 20 degrees.
Cabin Description
The K-701 wheeled tractor has a double cab with a good heating and ventilation system, which provides comfortable and convenient working conditions for the driver. On the frame is a welded pedestal, to which a double cabin with two doors is attached. The cabin is sealed all-metal. A favorable climate inside is facilitated by ventilation, heating and thermal insulation systems. The driver's comfort is ensured by the presence of a sprung seat, which incorporates a double-acting hydraulic shock absorber. The stiffness of the seat spring can be adjusted. Adjustment is made taking into account the weight of the driver. Also inside the cabin there is an additional chair.
Thanks to the separate-aggregate system and three-point device, it is possible to aggregate the tractor with various agricultural implements.
The system includes a hydraulic system for controlling the mounted device and actuators of agricultural machines.
A gear pump, hydraulic tank, control valve, locking devices, hydraulic cylinders and hydraulic lines make up the hydraulic control system of the mounted device.
Lighting of the external space is carried out with the help of headlights and lamps located in front and in the back of the cab, as well as on the wings.
Optional equipment
This equipment allows you to expand the scope of the agricultural machine. Thanks to him, it becomes possible to conduct a certain type of work. The installation of equipment on the K-701 tractor also contributes to an increase in tractor utilization and economic efficiency.
Additional equipment includes:
- A set of reverse control units. The set makes it possible to use a tractor with mechanisms that require a reverse mode for their operation.
- A set of power take-off shaft (PTO) nodes . It provides the ability to work with mechanisms, which include active working bodies.
A set of units is purchased separately by placing a special order.
