Among the difficulties which beset the creators of the homemade mini-tractor (MT) at every step, or three, judging by editorial mail, nesereznaya: the complexity of vehicle development is quite reliable and strong engine, compact transmission and rear axle, whose design is largely determined by the mobility of the machine, and its appearance, and maximum ground clearance…
“Hello, dear editors! Write “M” from 1969. Drawing magazine has fulfilled a number of projects. Pleased with them, that is, on all hundred. Particularly pleased with microtracker Amurchonok, has become my reliable assistant. He will plough the ground, and weeding perform, and hilling plants with it — no problem. And required construction works: load, which should drop the mortar (concrete) is thoroughly kneaded. I would like to equip your microtracker potato. The same as in the photo stitch “M-K” 5’89. If you publish the blueprints, then the fall will have time to do everything. To harvest potatoes to carry on their plot for not using old-fashioned shovels, and a modern, mechanized way.
Should get hold of your domin part with the land and animals type cows, as memorized from childhood tongue Twister “In the yard — grass, grass — wood” begins sometimes to acquire particular urgency and relevance.

At the mere recollection of this back sometimes whining begins. And then there is worries associated with hay…
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.
“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.
