The seeding machine «AGRAER-850H» is a pneumatic seeder cultivator designed to operate on both fields treated in the usual manner, and for sowing stubble without prior plowing. The complex allows a single pass processing and soil preparation, sowing with fertilizer, harrowing and packing of soil. General view of the seeding machine with the working bodies in the transport position shown in figure [1].

North made strips 15 centimeter wide, which provides more favorable conditions for seedling development in comparison with the usual drill sowing. Structurally provided sowing grain with density per hectare of sowing and seeding depth, installed by the consumer, taking into account local conditions, while the introduction of fertilizer. Specific requirements for soil and climatic zones will be charged. Control of seed and fertilizer, as well as the number of revolutions of the fan impeller by means of electronic control system seeding SLE «Arish» AM-8,5/28.

Hydraulic line rotary screw provides self-loading seed and fertilizer in the hopper. After separation of the bunker seeder «AGRAER-850H» can also be used for cultivating and compacting the soil. Technical characteristics of the seeding system is shown in the table.

Transportation unit on public roads is carried out in a disassembled form. Transport speed should not exceed 25 km/h. Getting started seeding system is as follows:

- after assembly unit lubricate friction components and spare parts at the points where installed nipples. Bring the tire pressure to the recommended. Visually check the tightness of all fasteners;

- installed on all cylinders rods adjust the depth the same sets of constraints. Bleed the hydraulic cylinders and put the side openers and central frames at the same level above the ground;

- load the hopper, calibrate seeding units and set the desired seeding rate on the calibration gearbox. Calibration is performed at each change of the form of seeds and at least two or three times a season at sowing the same culture;

- start the engine, set the desired fan speed (2500...3600 rpm/min for wheat, rye and barley). Rotate the handle on the calibration transmission, check the uniformity of the grain of the ports rash all openers. Finally, the fan speed is set empirically at normal receipt of grain to the coulters. When the fan is running check on the rumor air leaks through the seal cap hopper compartments;

- fit the piston rods of the main frame transport stops, lift the wings, set the locking pins, tow seeder in the field and on a flat area to set the desired seeding depth by changing the number stops on stocks cylinders depth adjustment;

- planting and maintenance of the seeding system must be carried out in strict accordance with the operating instructions and safety regulations by qualified personnel.

Before installing the program on the storage space required:

- clear the complex of dust and dirt, paint the damaged areas, brush the exposed parts of rods of hydraulic cylinders preservative oil;

- thoroughly clean the remnants of fertilizer openers. Bolts openers kerosene or diesel oil wash;

- completely cleaned of seeds and fertilizer auger and sowing machinery. Open rubber cap at a lower portion of seed tube arrangements;

- to cover the details of the mechanisms of seed with a thin layer conservation and oil.

Seeder «AGRAER-850H» registration No. 001 is designed and manufactured by JSC «Malmyzhsky factory for repair of diesel engines» (612921, Russian Federation, Kirov region, city Malmyzh, str. Friendship, 2) has been adopted in accordance with the requirements of the state standards and applicable technical documentation and found fit for service. This seeder provides a process corresponding to the applicable standards on sowing machine [2].
