Treatment of soil with electrofret. Especially for owners of cottages, gardens, gardens (see, for example, “M-K” 3’83, 1Г90). And in conditions when the prices are steadily rising, when the use of tillers (not to mention scarce mini-tractors) sometimes becomes economically feasible, electrophotonic on small plots of land, that is, out of competition. Convenient and relatively inexpensive, besides, equipped with special devices, they not only allow you to loosen the soil, to weed or hoe the plants, But also to successfully complete a number of other necessary household works.
AND FURROW AND PIT
“Mini tractor, description and sketches of which were published in No. 3 of the journal this year, I really liked it. As, apparently, the other readers of the “M-K”, there was a desire to make much-needed in an economy car-wagon. Moreover, because the engine pumps, and Azovskoe the clutch, and main gear from the electric cars available are already available. Constrains only the lack of information about what the suitable mini tractor front axle, frame, support system. I will be glad to read about all this on the pages of your favorite magazine.”
Amateur designers sometimes even adulthood may surprise the naive, and young, on the contrary, thoughtful and original solutions. And as an interesting personality, whose signature is a brief article describing the construction.
Amateur Designers often used in the transmissions of their cars, the chain transmission. And sometimes faced here what problem: for the calculated gear ratio chain couples find it difficult to choose ready-made sprocket with the desired number of teeth. But them it is possible to make yourself using the jig, assembled on the basis of the gear closest to the desired amount. Suppose you need a sprocket with 26 teeth and pitch of 19,05 mm. will Select the gear with the same or similar number of teeth. For example, 27. (In this case, the gear ratio will change slightly by 4%.) The gear is hardened, has a thickness of 19 mm and a bore diameter of 20 mm.
The proposed development is suitable for plowing the infield with a small plow, loosening the soil using the excavation tool. In addition, this cultivator can perform the planting and ridging of potatoes.”The heart of the” mechanical assistant (power plant) the engine of the scooter Elektron with forced air cooling and handles the throttle and clutch (with cables taken from the same scooter). The drive sprocket of the engine is also “a regular”. Gear changes can be left motorolleri, rope. But it is more convenient to bring it directly to the spar tillers. The programs will switch with levers and rods.
