We return to a universal small-sized agricultural machine WSM-2 “Cinderella”, designed and built by members of the primary organization of VOIR Seversk secondary school № 44, Krasnodar region (“M-K” №9 1980, №6, 1981). Designed for use on the school experimental plot, student production brigades, in the household plots, collective and state greenhouses, USM-2 can already carry more than a dozen kinds of operations. Nevertheless, Seversky, students continue to improve “Cinderella” — come up with new and new agricultural tools that extend its capabilities. Today we will talk about two such soil-cultivating aggregates: cultivator and mower.

Parameters and characteristics of the model correspond to the categories Ѕ8А and Ѕ8В. The diameter of the container under the engine selected in accordance with a cross-section of the sleeve (MRD-2,5-3-3 or MRD-5-3-3). We present several design and technological recommendations for the production model.
First domestic FWD. What vehicle did not invent tireless automakers! Their drawings were cars with engines at both the front and rear, with the leading front wheels and rear wheel drive and the most advanced authors with a drive to all four wheels…
A failure to “stand” due to poor paint quality model. A crucial role when applying color coating plays spray. I tried them for twenty years are many, but none fully satisfy me. That’s why in the end had to undertake the designing yourself. Took a commercially available spray “Shine”, refined some details and making some new ones. But in principle the device fully to make yourself; all of its elements are quite simple.
The washing machine is firmly established in our everyday life. And if in cities, the connection of washing machines to the water supply will not cause a problem, in rural areas, where there is no Central water supply, and take water from springs and wells to run such a job much more difficult. And it is caused primarily by lack of water-supply system or insufficient pressure in it. Generally, washing machines are designed to work with the pressure of the incoming water 0,5 — 10 bar, which can only pressurizing pump either based on Autonomous water station (the latter is possible to buy it now at the price of 5000 rubles).
Body of many Amateur furniture and other structures are often provided with support feet. But the support surface, which is fitted to a product is rarely perfect flat and horizontal. Below the design is not “played” under the feet placed pads.
Blessed be the day and hour when the person came up with the idea to put the cartridge for fastening the tool to the shaft of the motor. As a tool the drill has become a widespread tool. Why not just make a drill: drill, cut, grind, Polish, mix, mow, and plow … even now!

Considering the number of characterizing a working volume of cylinders of internal combustion motors produced by our industry, necessarily pay attention to the typical “failure”. Unfortunately, the motors of the class from 2.5 to 5.0 cm3 we did not exist. However, these engines required for flight training, high-speed radio-controlled model airplanes, scale airplanes. They can also be set on auto and advanced.
