SZT-3,6 seeders. simultaneous seeding of grain and grass
Trailer seeder grain SZ 3 6 is widely used in the fields of agro companies in Russia and neighboring countries. This universal equipment can be used with the seeds of cereals, legumes and some cereals crops. Suitable for sowing barley, oats, peas, buckwheat, millet and other crops. One of its many benefits is the ability to apply fertiliser to a depth of up to 80 mm simultaneously with the sowing. Depth and sowing speed are controlled by special sensors. Seeder is used with tractors of different traction class, mainly with MTZ-80 (82) and similar.
Design and specifications of the SZ 3 6 have been designed so that the equipment is a relatively high speed and versatility.
The basic elements of a seed drill:
- Steel welded frame with step and hitch. Serves as a base of construction.
- Pneumatic wheels (2 pcs). Relatively high driving speed (up to 12 km/h in the field).
- Tanks for fertilizers and seeds (2 pcs.).
- Reel to reel seeders (24 pcs). Provide capture and transportation of seeds into seed tubes.
- Reel toothed type seeders. Served for gripping and transporting granular fertilizers (24 pcs.).
- Seed tubes to move seed and pellets to the coulters. Are made of rubber, corrugated.
- Double disc coulters. ensure the placement of seed and fertiliser in the soil.
- Finger-type or chain-type headers. Ensure the placement of seeds and pellets into the soil. Can be used together, in which case the chains are responsible for the final leveling of the soil.
The seeder is used in conjunction with a tractor:
- Seed and fertiliser pellets are rolled from the relevant compartments into the chambers of the sowing units.
- Seed rollers turn, catch seeds and pellets and convey them to the seed pipes. This only works when the coulters are in the deepest position.
- Coulters form furrows in the soil to the correct depth (up to 8 cm).
- Seed and pellets go through the seed tubes into the hollow between the coulter discs and then are rolled into the furrows on the guide.
- The grooves are immediately terminated by means of trowels or chain-links.
Rotation to shafts of sowing units is transferred from support wheels by means of gearing and overrunning clutches. Disengaging transmission when lifting coulters ensures disengagement. Coulters are connected to the frame by hinges and reins, as well as to the lifting mechanism through the pushing fork and boom. Similarly, the square shaft of baffle plates is connected to the mechanism. The lifting mechanism is operated by the tractor hydraulics.
Fertilizer is used only with pellets (mineral or organic).
- SZ-3,6A. single-row version for use on fields up to 40 hectares.
- SZ-3,6A-01 with one disc coulter. Used for fertilizer application and sowing winter crops without pre-tillage.
- SZ-3,6A-02 with corrugated coulters and headers. It is used for sowing flax in two lines with the embedment depth of 10-30 mm. Also suitable for grain and leguminous crops.
- SZ-3,6A-03 with full-fledged coulters. Developed for sowing on light soils: sandy, sandy loam. Not suitable for use on heavy loams.
Chapter 3. Agriculture in the pre-revolutionary village
Before the revolution, land belonging to the village was distributed among the villagers in proportion to the number of family members (eaters), with adults being allocated a larger share than the elderly and children. There was no bar land. All land was divided into arable, hayfield, and cattle grazing land. Arable and hayfield land was assigned to each family for permanent use. Residents used to fertilize their land and could sow whatever they wanted. For haymaking, certain areas of land were also allocated where hay could be made. Residents took care of their plots, prevented the growth of weeds, small trees, and built sheds on them to store hay. Common use was land for grazing cattle. It was clear from conversations with their ancestors that land was not sold to individual inhabitants, but was distributed so that all families could feed themselves and give another part of their produce to the state, somewhere around 10%.
The soil in our area was not very suitable for growing grains. loams, sands, podzolic soils. but the village still sowed grains, although the yields were low. Villagers kept a lot of cattle and took all dung out to the fields as fertilizer. Mainly rye was sown in the fields. They also sowed wheat (barley), oats, peas, millet, buckwheat, hemp, flax.
Two Chainsaw Secrets | Turning a Tree into Perfect Boards
Land was ploughed in the beginning of the century mainly by ploughshares, ploughs were rare, only the rich had. The ploughshare is a no-till tool. Today scientists recognize that the no-till method of cultivation has advantages over others, since it more effectively preserves moisture in the soil, which is especially important for arid regions. Horse was the main draught force. Almost all families kept horses, because it was impossible to live in the village without one at that time. neither to plow the ground nor to carry hay or firewood. A horse was used as a means of transportation.
The earth was loosened with self-made wooden harrows made of fir trees with long branches and bound into separate sheaves. Grain was also sown by hand. Men with “sowing machines” walked across the ploughed field and skillfully scattered the grain in a 4-5 meter strip. So as not to make a mistake and sow twice, or vice versa. to leave no mishaps on the plot, twigs were made of twigs. “Mostly children helped the grown-ups to sow.
Cereals were reaped by hand with sickles. The pressed rye or other crops were bundled into sheaves which were put into so-called sheaves. Six to eight sheaves were stacked vertically with ears facing each other and covered by a sheaf. The sheaves dried up in the sheaves and the grain did not get wet with rain. The sheaves are then taken to their threshing floor and filed into baling stacks or put into stacks in the fields.
Each family, or several related families, had their own threshing floor. a large room with a smooth wooden floor and a riga. There was a brick oven in the barn, which was heated “black,” and a wooden deck of poles, where the sheaves were put vertically for drying. As a rule, the barn was loaded in the evening, the oven was flooded, and the sheaves with grain dried all night long. The threshing was done in autumn, after the harvest, in October-November. The sheaves were threshed by hand with chains, made of long stalks with wooden beaters, loosely tied at the ends. The whole family would go out to thresh early in the morning, after dark, with lanterns to finish before breakfast and have time for the day’s work. The bundles were pulled out of the barn, stacked in the middle of the threshing floor in two rows, ears inside out, the bundles were cut and threshed by hitting the ears and straw with the beaters. After threshing the straw was gathered up, bound in large sheaves and stacked outside. Spring straw was fed to livestock, and winter rye straw was used for household needs. roofs were covered, mattresses were stuffed, and bedding was used for livestock. received grain, already dry, suitable for long-term storage, was checked, separated from chaff and necessarily measured with special measures (like lightweight pails). Each grain measure held about one pood (16 kilograms) of grain. Ready dry hemp was transported to granaries. Chaff was collected and used to feed livestock. Such technology of grain production by hand is not very productive, but economical enough. Losses of grain were minimal. To make flour, grain was milled in mills, of which there were few in the county. Most of the mills were water mills, built on the banks of rivers or ponds. often grain was ground in home millstones.
Hemp and flax were sown for oil and fiber. Hemp grew up to the height of 1,5-2 meters. The stalks were pulled out of the ground with the roots, dried, and threshed. Kernels were dried, pounded in mortars, ground, heated in ovens in trays, poured into canvas sacks, clamped in special wooden vice with wedges, and oil was squeezed out, very fragrant and tasty. Straw hemp was soaked in ponds, the fiber was then easily separated, it was used to make strong ropes and ropes.
They sowed a lot of flax, they needed cloth-cotton, and they needed oil too. Flax was sown very densely on clay soil, so that the flax stalks would not lodge in the 50-60 cm tall stalks. Flax in blossom is very beautiful, flowers blue, quite large. Flax has almost no leaves, one long thin stem, and only on the top there are a few leaves and a round box with seeds. After the seeds had matured, the flax was threshed, i. e.е. They pulled it out of the ground, tied it into sheaves, dried it, threshed it, and got the seed. The seeds were used to make oil in the same way as hemp. The threshed flax straw was spread in the fields after the grass was cut, on the straw stalks. Autumn rains and dews helped to separate the fiber from the inner core. Straw was harvested, dried in the same rigs and processed, first in chaffers, which separated the main fire, and then the fiber was rubbed with light thin wooden planks (trepalers). The result was a smooth, fine fiber, suitable for spinning and making yarn. Waste materials (brushes or tow) were used at home to make ropes and as sealant in the construction of houses and for other purposes.
Many residents wove their own canvases. As a child, I watched my grandmother, and then my mother, weaving canvas on a homemade loom called a crone. First the flax was spun, the yarn was produced. The threads are thin and strong. Mainly in winter both old men and young men were spinning. Young girls used to take spinning wheels with them to the gatherings and at the same time they had a good time and did useful work. Guys and obligatory accordionist came to the gathering, sang and danced. I and my peers also went to such gatherings after the war, a way of life long persisted from our days. Then the threads are used to make a warp. threads are wound onto a reel in an amount that depends on the desired width of the fabric. The length of such a warp was about 12-15m and depended on the number of rows wound on the reel. Then the warp is wound onto a drum behind the crochet, the thread is passed through so-called “threading”, there are several of them, depending on the complexity of the pattern of the fabric, and then the warp is passed through the “reed. a special lattice of thin wooden strips. With the help of hooks, certain rows of thread are raised or lowered by special pedals and a shuttle with a hook, on which threads are wound, is let through the gap between the rows of thread. The weft is pressed tightly to the fabric with the reed. The ready-made cloth is wound onto the front drum. The pattern of the fabric could be simple, such as calico, or more complex in the form of herringbone. I have seen towels woven this way a long time ago, very fine and beautiful, not inferior to the factory ones. The woven canvas has a gray color, unsightly in appearance. To whiten a canvas it was spread in spring on the snow (on the thawing snow), the moisture of the thawing snow and the sun made the canvas completely white and beautiful.

Pulling back when felling trees
Consider how to cut a tree next to the house (this method is also suitable for felling a tree not in the direction of its natural inclination). This requires the use of extra insurance against the wrong fall of a felled trunk. A pull cord made with a strong rope, winch, spring, rubber band, or other stretching material can serve as it.
A rubber harness that acts as a stretch is attached to a steel pin hammered into the ground, another tree standing nearby. It can also be attached to another stationary object. When making notches such a rubber band will pull the trunk in the right direction.
If a rope serves as a pull, it should be tied to the top of the tree being felled (its length should be longer than the height of the tree). Once one person has made the felling notches, another person must pull the rope in the direction of the anticipated fall of the tree.
Briefly about the essentials
In order to cut a tree, one must not only imagine the whole process, but also have the right physical qualities, a good chain saw and suitable clothing.
Before felling a tree, you should choose a method of felling, inspect the place of work and prepare the necessary tools.
After the upper 45° felling notch and the lower horizontal notch on the other side of the tree, felling is performed.
The wood should fall toward the wedge-shaped undercut when felling.
For small trees you can use the technique of just felling in the slanting direction.
Cutting down trees with a pullback or with a hang-up is performed by professionals using additional equipment.
