Seeder SZP 3.6 is an agricultural machine designed for planting grain crops (rye, oats, wheat, barley) and leguminous crops (beans, peas, lentils) in rows with a distance of up to 15 cm, as well as for fertilizing and rolling the sown rows.
The degree of unification of components and parts within the SZP 3.6 family of seeders reaches 77-98%, which simplifies the manufacture, operation and supply of spare parts.
The seeder can work both in a single-seeder and in a multi-seeder row unit (3-4 seeders each). In single-seeder units, the SZP 3.6 seeder is aggregated with tractors of traction class 0.9-1.4, and in multi-seeder units - with tractors of traction class 3.0-5.0, more powerful than the tractor.
A voluminous hopper for seeds and fertilizers, pneumatic support wheels, rolling bearings, hydraulic lifting and lowering of working bodies, the ability to use hitches to assemble multi-seeder units with power-saturated tractors provide high quality sowing with simultaneous fertilization, high productivity, simplicity and convenience in operation, reliability no worse than seeders.
Device of a seeder SZP 3.6
The basis of the unit is a metal frame. It rests in front on two pneumatically driven wheels. On top of the frame are all control and adjustment mechanisms, as well as a hopper for fertilizer granules and seeds.
The openers are raised and lowered hydraulically (an external hydraulic cylinder is fixed to the frame base). Ring type rollers are hinged to the frame. A three-speed gear reducer connected to the wheels of the machine is switched by a lever. Torque is transmitted from it to the shafts of the sowing mechanisms - a chain drive is used for this. An uncoupler is used to stop seeding when openers are up.
An overrunning clutch is used to transfer rotational energy from both wheels or from two rollers located at the edges. When the machine is operating, the coulters make trenches, where they fill up with the necessary interval of grain and fertilizer coming from the hopper through the funnels into the coulter sockets. The edges of the trenches then crumble naturally, covering the seed. The following rollers "tread down" the surface of the soil, and it is leveled with a special trail-harrow. As structural materials, the same ones are used.
1 - seed ducts; 2 - frame; 3 - mechanism for raising and lowering openers; 4 - grain fertilizer box; 5 - suspension; 6 - front end with a trailer; 7 - reducer; 8 - foot board; 9 - rollers; 10 - coulters. To use the unit, you need a tractor to which it attaches. As already mentioned, with the help of hitches of the SP type, you can create a multi-seeder design. Just keep in mind that only a sufficiently powerful tractor (with a traction force equal to 3 or more) can move it.

Video review of the SZP 3.6 seeder
The design of the seeder allows you to apply granular mineral fertilizers simultaneously with the sowing of grain crops, pack the soil in the sown rows, maintain the same seeding rate in curved areas, transfer the coulters from the working position to the transport position using the tractor hydraulics, replace the rear drive wheels with four sections of the press rollers (for press option) on soils subject to wind erosion. Thanks to the use of bearings in the coulters, maintenance time has been reduced, as the number of lubrication points has been reduced.

Seeder SZP - the most popular seeder in the world
Planter Champion
It is difficult to find an agronomist who is not familiar with the "szshka" - the SZ seeder. The first seeder of this model was created almost half a century ago. During this time, it has become a classic grain ordinary trailed machine. In the USSR, they were produced at the Kirovograd plant of agricultural machines "Red Star" (the modern name "Elvorti") in Ukraine, in Russia, "szshki" were made by the factories "Belinskselmash" in the Penza region and "Sibselmash" in Novosibirsk, they were also made in Kazakhstan.
The model turned out to be so successful that on the basis of the SZ-3.6 seeder, many modifications were developed: coulters for light soils, narrow-row ones for ordinary and stony soils, grain-grass, single-disk, roller for peat soils, flax, etc.
The high level of unification of components and parts within the family of seeders greatly simplified the manufacture, operation and supply of spare parts, combined with simplicity in design, maintenance and overall reliability in operation - all this contributed to the wide distribution of sowing machines.
In the vast territory of the former Soviet Union, there is probably not a single farm where these seeders are used. At the turn of the century, more than one and a half million such seeders had already been produced. Not a single seeder in the world was produced in such huge quantities.
From "szshka" to "szshushka"
For work on soils subject to wind erosion, a grain-fertilizer press seeder, SZP-3.6, was developed. In such a seeder, sowing takes place with the simultaneous rolling of each sown row. In addition to protecting the soil, the packer rollers not only protect the soil from erosion, but also ensure uniform sowing and uniform seedlings.
In 2016, the Rubtsovsky Plant of Spare Parts began to produce seeders SZP - in addition to the already wide range of plows and harrows. The VITA seeder "shot" - adapted to our conditions, it sows where six times more expensive imported ones are not able to work at all, not to mention their domestic clones.
What's new?
Of course, it was no longer the same seeder that left the Kirovograd workshops 50 years ago - domestic and foreign agricultural engineering has stepped far ahead. The design of components and assemblies and SZP seeders has changed and improved.
In the VITA seeder, the width of the working grip remained traditional - 3.6 m. The volume of grain fertilizer hoppers increased by almost 1.5 times, which made it possible to load large volumes of seed, reduce the number of stops for refueling and increase productivity.
The seeder uses a familiar and reliable gearbox, more precisely, two open (three-stage) gear gearboxes located behind the seed boxes. Together with chain drives, they make up the drive mechanism for seed and fertilizer sowing machines.
A modernized double-disk opener is used, the disks of which are offset by 6 mm relative to each other, which reduces traction, increases the resource of the opener and avoids clogging. As a rule, disc coulters work well in all soils. Due to the rotation of the discs, they almost do not clog and do not stick, they allow sowing at high speeds, they have the ability to individually copy field irregularities.
Reinforced "problem" units: beam, drawbar, footboard. The position of the drive gear has been changed. In the original “szpshke”, the rink hit the drive at the slightest bump. With the VITA seed drill, this problem is solved - the roller is moved back by 7 centimeters, and does not come into contact with the drive.
To take into account these moments, direct feedback from the consumers themselves was needed. Before being put into production, the seeder not only passed mandatory tests at the Altai MIS, but also worked for a season on the farms of the Altai Territory. Comments and suggestions were taken into account and worked out.
New Perspectives
According to the Rosagromash Association for 2016, the Almaz association is in first place among Russian manufacturers in terms of shipments of reversible plows, chisel plows and disc harrows, in second place in Russia in terms of shipment of moldboard plows, and in third place in terms of shipment of mechanical seeders. .
Soil cultivation, plows and harrows are traditional for Almaz, and the high results here are not surprising. But the third place in the shipment of seeders is a great success, because their production was launched only in the previous year, 2015.

The TDT-75 tractor is a tracked vehicle of the third traction class. Produced by OJSC "Altai Tractor", served as the basis for the creation of modern skidding mechanisms TT-4 and TT-4M.
The machine has sufficient power to transport large- and medium-sized wood from cutting sites to storage areas in the absence of equipped roads.
It is used for loading and unloading of packaged timber. The chassis allows joint use with trailed and mounted equipment for various purposes.
TDT-75 effectively performs:
- logging processing of trunks, whip fragments;
- moving the trunks with the top back and forth;
- dragging cargo, with partial and full loading or suspension.
Unit Features
- Low specific pressure on the soil. Wide tracks provide movement on uneven forest roads, snowy areas, swampy terrain.
- The diesel engine, in its time, is quite economical in terms of fuel and lubricants consumption.
- The chassis of the machine is universal - special devices are mounted on the platform, used in logging and primary processing of wood in off-road conditions.
- Ground clearance provides sufficient cross-country ability.
- Increased traction power transmission, high reliability of the undercarriage.
- Metal protection mounted on the bottom of the frame.
- The motor installed in the cab does not provide comfortable conditions for the driver.
- Compared to the skidder TDT-55, the maneuverability of the unit in forest conditions is reduced due to the large weight and dimensions.

Power point
The skidder is equipped with a D-75T-AT diesel engine, a modification of the D-60T engine.
Engine for 4 cycles, with an in-line arrangement of 4 cylinders in a cast-iron block, the fuel mixture is formed by a vortex-chamber method. The power unit has power parameters of 75 liters. With. at 1500 crankshaft revolutions per minute.
Changes have been made to:
- fuel supply system. The fuel pump provides fuel supply with a capacity of 18.0 kg / h;
- the shape of the combustion chambers and the bottom of the aluminum cylinder. Injectors and cylinder head seats are placed at an angle of 55 ° to the horizontal;
- system for filling cylinders with air;
- suction manifold;
- starting gasoline engine systems.
power transmission
The clutch is a mechanism for two constantly closed discs, dry type.
Drive shafts provide transmission of the motor torque to the winch and transmission mechanisms. A small cardan-type shaft connects the clutch to the transfer case. A large shaft mates gearboxes and distributions.
The gearbox shafts rotate on bearings pressed into the box crankcase.
Important! The box provides 5 modes of torque transmission for forward movement and 1 for reverse direction. The locking device does not allow changing modes when the clutch is engaged.
Gearbox control - from the driver's cab through a roller with a cardan assembly.
Chassis
The welded frame is made of 2 steel spars connected by three transverse pipes, a protective and a frontal sheet.
In the design of the suspension, spring and balancer units are used.
Sowing an entire field with wheat or sunflowers is a time-consuming task, and one cannot cope with it without special equipment (do not throw seeds in handfuls, as in the old days). Agricultural machines, called seeders, do this skillfully and accurately. And such an aggregate as SZP-3.6, along with seeds, will also feed the earth with fertilizers.
The Kirovograd enterprise "Chervona Zirka", founded at the end of the nineteenth century by two brothers from England, used to be called the Elvorti plant. At one time it was the only European manufacturer of many types of agricultural machinery. It was on it that in 1929 the first seeder driven by a tractor was invented (before that they were horse-drawn).
The modern ordinary type SZP-3.6 (otherwise, ASTRA 3.6P) is one of the modifications of the common SZ-3.6 model, differing from it in a front end with two pneumatic wheels. In addition, ringed rollers (four sections) are located in the rear of the unit under the frame, compacting the ground. Because of the latter feature, the machine is also called a press machine.
Purpose
This device is useful when barley, rye, oats, wheat or any other types of grain are ready for sowing in the bins. It can also be peas with soybeans or more rare chickpeas with rank - in general, any legume. You can also use seeds of a different type, which have similar consumption rates and dimensions. For example, millet, buckwheat or rice.
It is convenient that they can be sown immediately on 24 rows. And if you use a special hitch and connect two or more machines, then the number of rows will increase by two to three times. The necessary fertilizers in the form of granules are immediately introduced into the soil. Their rate, as well as the number of seeds, can be regulated by a special mechanism - a variator.
Photo seeder SZP-3,6 
Advantages and disadvantages
Advantages:
- The design of the machine is very simple.
- The seeding depth can be very conveniently and extremely quickly adjusted (in increments of one centimeter).
- The speed of work is quite decent.
- The ability to make a line of two or three cars and immediately cover a huge area.
- Convenient adjustment of the amount of seed and fertilizer material.
- Rolling the earth, retaining moisture in it.
Flaws:
- The brackets connecting the footboard to the frame are a bit flimsy.
- The compartments for fertilizers and seeds have separate covers - if you need to sow a little, then this is inconvenient.
- The double-disk type coulters used here allow sowing only in rows, and not in strips, like more efficient single-disk devices. Therefore, this model is sometimes upgraded by changing the openers to single-disk.
Device and principle of operation
The basis of the unit is a metal frame. It rests in front on two pneumatically driven wheels. On top of the frame are all control and adjustment mechanisms, as well as a hopper for fertilizer granules and seeds. The openers are raised and lowered hydraulically (an external hydraulic cylinder is fixed to the frame base). Ring type rollers are hinged to the frame.
A three-speed gear reducer connected to the wheels of the machine is switched by a lever. Torque is transmitted from it to the shafts of the sowing mechanisms - a chain drive is used for this.
An uncoupler is used to stop seeding when openers are up. An overrunning clutch is used to transfer rotational energy from both wheels or from two rollers located at the edges.
When the machine is operating, the coulters make trenches, where they fill up with the necessary interval of grain and fertilizer coming from the hopper through the funnels into the coulter sockets. The edges of the trenches then crumble naturally, covering the seed. The following rollers "tread down" the surface of the soil, and it is leveled with a special trail-harrow.

To use the unit, you need a tractor to which it attaches. As already mentioned, with the help of hitches of the SP type, you can create a multi-seeder design. Just keep in mind that only a sufficiently powerful tractor (with a traction force equal to 3 or more) can move it.
In order for the crops to be sown to receive the required amount of nutrients, moisture and light, they must be evenly distributed over the entire cultivated area at a given depth. For this, special machines are used - seeders, which allow you to sow quickly and efficiently. And such equipment as grain seeders of the SZP series, manufactured by the Chervona Zirka Kirovograd plant, can simultaneously apply mineral fertilizers with seeds.
Depending on the method of seeding, there are ordinary, dotted, nested and square-nested seeders. Sowing equipment that simultaneously applies mineral fertilizers with seeds is called combined. Also, seeders are divided into special and universal. Special mounted units are used for sowing only one or 2-3 crops. Universal trailed sowing equipment is used for sowing grain, legumes and oilseeds, green manure, etc.
SZP-3.6
The SZP-3.6 seeder was developed directly for row sowing of agricultural crops with the introduction of granulated mineral fertilizers into the soil. This model of sowing equipment is a modification of the SZ-3.6 seeder and the difference lies in the presence of self-aligning front pneumatic wheels and rear rollers.
The basis of this sowing equipment is a metal frame, which is supported in front by two pneumatically driven wheels. Adjusting devices and control mechanisms, as well as quite capacious containers for seed and fertilizers, are mounted on top of the chassis. The openers are lowered and raised hydraulically.
Advantages and disadvantages of equipment
The advantages of the planter include:
- simplicity of design;
- convenient and quick adjustment of the seeding depth;
- good working speed;
- the possibility of compiling a sowing complex from several seeders;
- convenient adjustment of the amount of applied seeds and fertilizers;
- soil compaction to retain moisture.

Among the shortcomings of the unit, it is worth noting:
- insufficiently strong brackets connecting the footboard with the metal frame of the equipment;
- double-disk coulters make it possible to carry out only ordinary sowing.

SZP-3.6A
Grain fertilizer seeder SZP-3.6A is a highly efficient equipment for sowing major crops. Thanks to the design of the unit, simultaneous injection of fertilizers with seed, soil compaction and maintenance of the sowing rate throughout the entire process are possible.
The SZP-3.6A grain-fertilizer press seeder has capacious containers for seed and granular fertilizers, support-driven pneumatic wheels, rolling bearings, a hydraulic system for raising and lowering working units, as well as the ability to compose a sowing complex, which allows achieving high-quality sowing, high productivity , reliability and operating comfort.
The seeder of the SZP-3.6A series is very popular among farmers and received the most positive feedback. This equipment can be purchased from official dealers, as well as used units from farmers at a very reasonable price, and besides, there are no problems with the purchase of spare parts.
SZP-600 "Agromash"
This model of sowing equipment is designed for simultaneous introduction of basic agricultural crops and mineral fertilizers into the soil by an ordinary method on areas with a slope of up to 8˚ with a leveled and loosened surface. SZP-600 consists of a metal frame with markers driven by a hydraulic system, hoppers for seed and granular mineral fertilizers, supporting wheels, a pneumatic seeding system and a seeding device drive mechanism.
Seeder SZP-600 produced by "Agromash" performs high-quality sowing work and has satisfactory performance.

Sowing operations carried out by seeders of the SZP series are distinguished by high-quality and accurate introduction of seeds into the soil simultaneously with granular mineral fertilizers. This equipment is reliable, easy to set up and operate, and can significantly save time, fuel and, accordingly, money. The purchase of the above seeding units is economically justified and quickly pays for itself.
Sowing an entire field with wheat or sunflowers is a time-consuming task, and one cannot cope with it without special equipment (do not throw seeds in handfuls, as in the old days). Agricultural machines, called seeders, do this skillfully and accurately. And such an aggregate as SZP-3.6, along with seeds, will also feed the earth with fertilizers.
Seeders SZP-3,6
The Kirovograd enterprise "Chervona Zirka", founded at the end of the nineteenth century by two brothers from England, used to be called the Elvorti plant. At one time it was the only European manufacturer of many types of agricultural machinery. It was on it that in 1929 the first seeder driven by a tractor was invented (before that they were horse-drawn).
The modern row seeder SZP-3.6 (otherwise, ASTRA 3.6P) is one of the modifications of the common SZ-3.6 model, differing from it in a front end with two pneumatic wheels. In addition, ringed rollers (four sections) are located in the rear of the unit under the frame, compacting the ground. Because of the latter feature, the machine is also called a press machine.
Purpose
This device is useful when barley, rye, oats, wheat or any other types of grain are ready for sowing in the bins. It can also be peas with soybeans or more rare chickpeas with rank - in general, any legume. You can also use seeds of a different type, which have similar consumption rates and dimensions. For example, millet, buckwheat or rice.
It is convenient that they can be sown immediately on 24 rows. And if you use a special hitch and connect two or more machines, then the number of rows will increase by two to three times. The necessary fertilizers in the form of granules are immediately introduced into the soil. Their rate, as well as the number of seeds, can be regulated by a special mechanism - a variator.

Advantages and disadvantages
Advantages:
- The design of the machine is very simple.
- The seeding depth can be very conveniently and extremely quickly adjusted (in increments of one centimeter).
- The speed of work is quite decent.
- The ability to make a line of two or three cars and immediately cover a huge area.
- Convenient adjustment of the amount of seed and fertilizer material.
- Rolling the earth, retaining moisture in it.
Flaws:
- The brackets connecting the footboard to the frame are a bit flimsy.
- The compartments for fertilizers and seeds have separate covers - if you need to sow a little, then this is inconvenient.
- The double-disk type coulters used here allow sowing only in rows, and not in strips, like more efficient single-disk devices. Therefore, this model is sometimes upgraded by changing the openers to single-disk.
Device and principle of operation
The basis of the unit is a metal frame. It rests in front on two pneumatically driven wheels. On top of the frame are all control and adjustment mechanisms, as well as a hopper for fertilizer granules and seeds.
