In the “M-K” is not just talked about different designs and the complexity of the tillers. They were mostly two-wheeled options. I think that the homebrew in vain underestimate the dignity of the unicycle scheme. Indeed, such a cultivator is a simple, inexpensive to manufacture and operate, lightweight, and therefore less soil sealing, maneuverable — able to work where two-wheelers do not go, and finally, it is convenient to storage — you can hang it with a bracket on the wall. On the other hand, such a scheme places high demands on the layout of units, since the position of the center of gravity of the machine in longitudinal and transverse direction determines the ease of working with it. When installing the engine over the wheel — even of small diameter — the overall center of gravity is too high. In addition, the relatively small weight of the required traction wheels with the ground a mere development of the cleats is not achieved. The solution to both problems is to shift the engine forward. This provides the minimum height of centre of gravity and at the same time, there is an allowance of force pressing the wheel down due to the balancing pressure of the operator on the handle. The extra traction helps in the cultivation front of the working body — the horizontal legs having a negative angle of attack.
Walk-behind self-built eager to make the most versatile. This is understandable: it has to perform a variety of agricultural operations. However, to create a design that is most optimal for any work at the farm, is not easy. So, powerful, heavy duty motor-plow, as a rule, is too broad and clumsy in the aisle, and brisk the tiller can’t beat plowing the dense earth. One solution to this problem is offering our reader from Krasnodar territory Vladimir Yakovlev. Its compact one-wheeled tillers will assist in the processing of the beds, will not damage plants close together and, if necessary, in just 10 minutes will turn into two-wheeled motor-plow.
In the “M-K” No. 8 for 1984, we talked about the greenhouse arch designs made by students of the Bauman district of Moscow. Its main load-bearing elements — the half-arches — been made of gymnastic hoops. This circumstance is strictly determined size of the greenhouse. But it is tempting to build on the same principle a more spacious and convenient in maintenance construction of a greenhouse. But here’s the problem: the material for poludov frame to find easy.
To prepare starch from potatoes at home I have several years helps… washing machine “Kama”. To turn it into productive avometers needed very little improvement. From a round steel plate d 189 mm and thickness of 0.5 mm did scratch the disk, propertyreal his thick nail So that the disc is not deformed, sawal-Deval edge, and the holes are filled evenly deposited on the workpiece concentric circles. Took the car activator, secured PA the disc grater on six M3 bolts with countersunk heads and set back. From thick durable Board, cut out the partition, the spacer wedge and cover the boot compartment.
A delicious and useful product — sauerkraut. Practical housewife, harvest it in the autumn as in the countryside and in the city. And the most time-consuming operation here is to shred the cabbage. Use and sharp long knives, and a special chopping. But no manual beats the convenience and efficiency with electric that you can do with your hands, taking some parts from an old washing machine.
Artificial fertilizers are much more effective if they are applied to the soil dissolved in water. However, to achieve an even distribution but the size of the plot is not easy — because most of the pellets don’t dissolve and drop out as sediment at the bottom of the bucket or watering can.
On private land, perhaps only a decorative grass — raygrass — tracking, scattering the seeds. The vast majority of annual flowers and vegetables planted in rows: so the plants are easier to handle and feed. But since seeds are small, often the shoots are too dense. You have to spend a lot of time pulling, away, by the way, is harmless to the root system.
Getting the design of this machine, I proceeded above all from the conditions of its future work. The soil in our area is mostly heavy loam, stones… and surface plots are far from perfectly smooth. In short, the operation was not easy. This fact determined the choice of the main parameters of the mechanism.
For simplicity, I decided to make the walk-behind, in-parzych, unicycle, and secondly, on the basis of units, components and parts of various machines manufactured in the factory. Took the frame of the motorcycle M-105. To do this, cut it up the pipe in four places: 60 mm higher than the front bracket of the engine mount 165 mm above the same rear bracket and 50 mm above the curved pipe going to the back of the pendulum fork (both sides).
