On the walk-behind tractor, most of the working units are hung from the rear by the hook-on bracket. When hanging working units, the balancing of the walk-behind tractor changes. In order to enjoy working on a walk-behind tractor, it is necessary to create its own balancing for each working unit. For this purpose, in front of the engine protective casing, I welded a horizontal crossbar to the footrest attachment system, and welded a vertical rod to its middle, onto which I hang loads (see photo). As cargo, I use a counterweight from old elevators measuring 210x210x90mm (I hang it on a vertical pin) or four metal pancakes with an outer diameter of 150mm found in a landfill, in which I drilled a hole with a diameter of 50mm in the center and which I hang on a pipe pre-mounted on the pin. Their thickness and weight: 40mm - 4.8kg, 45mm - 5.kg, 50mm - 6.kg, 70mm - 8.kg.
I balance the working units as follows. For the plow, hiller, cutter and harrow for clean harrowing (this is harrowing when hilling potatoes and seeding grain) I create such a balancing by hanging weights so that the equilibrium position occurs at the same distance to the ground, both from the lower slide and from the lower point of the worker unit. In this case, the walk-behind tractor has two stable positions: one, when you raise the control bar as much as possible and lean the walk-behind tractor on the lower skids (used when cleaning, servicing the working units and when stopping), and the second, when you lower the control bar down to interact with the soil ... In this case, when working, when moving and when turning, the vertical load on the arms is minimal. With rough harrowing (this is harrowing after harvesting potatoes, when you need to pull the tops from the field outside of plowing, etc.) .) I create such a balancing by hanging metal pancakes so that the load outweighs the harrow and the walk-behind tractor always tries to lean forward and drop onto the lower slide. In this case, when working, I press the control bar with my hands and press the harrow to the ground, and to release the harrow from the collected tops and grass, I loosen the pressure and slightly pull the control bar up - the walk-behind tractor is outweighed forward, rests on the lower ski and the harrow cleans itself.
As a result of using counterweight weights, we get:
- we balance the walk-behind tractor coupled with the working unit in each specific case in such a way as to ensure the minimum load on the hands and maximum convenience in work;
- the suspended load increases the total weight of the walk-behind tractor while working with the units and thus improves traction;
- the cross member and the pin welded in front play the role of the front bumper and protect the flimsy protective grille of the engine from breakage in case of accidental contact with an obstacle.
The plow is the main and most important working unit in land cultivation. A well-made plow is a guarantee of plowing quality, no slippage of the walk-behind tractor and enjoyment of the plowing process. Since the soil on my site is not just heavy, but very heavy, I have very serious requirements for the plow. A good plow is said to shave the ground, and a bad plow digs the ground like a pig. A good plow, after sinking into the ground, goes stably steadily, the depth of penetration does not depend on the density of the soil and it will never jump out of the ground itself, unless a rag, tin or something similar gets under the share. A good plow leaves behind an even, beautiful furrow with a vertical cut, in which a shiny track from a skid (field board) is visible on the bottom in the corner on the vertical and horizontal surfaces. The plow, which was initially incorrectly assembled, or which is worn out and requires restoration, does not go deep into the ground, and after it goes down it does not go steadily, “prowls”, strives to jump out of the ground, creates an increased load on the walk-behind tractor. The furrow after such a plow has the shape of a ditch, the trace from the runner is not visible, since the runner is not going there or not as it should. Working with such a plow turns into a mockery of the land and of oneself.
The share is geometrically correct and the heel design is perfect for plowing hard ground. The unit is collapsible, made of durable material. The materials for the production of the unit are not chosen by chance, since during operation the part is subjected to a large load. After the work of the attachments, the land is cultivated with a cultivator.
For each type of walk-behind tractor, for example, Cascade, Salyut, Neva or Favorite, the corresponding type of equipment is used. Today, there are also universal models that are compatible with any type of technology.
It can be quite difficult for a novice farmer to choose the right generator for a walk-behind tractor. However, not everything is as complicated as it might seem at first glance. The single most important factor to pay attention to is the power of the device. Whichever generator you choose for an agricultural machine, its power must necessarily exceed the total power of the loads under which the walk-behind tractor works. This will allow the device to work properly under a voltage of 220 volts without the risk of surges in the electrical network, and to power all electrical appliances available on the walk-behind tractor.
Often, inexperienced owners of walk-behind tractors purchase and equip their equipment with generators designed for installation on cars. This is the best option if the farm regularly uses a powerful heavy-duty walk-behind tractor. In other cases, it is impractical to buy such generators due to their high cost.
On the modern electrical appliance market, you can find a huge selection of generators designed for installation exclusively on walk-behind tractors. A wide range of products sometimes plays a cruel joke with novice farmers, as a result of which an inexperienced owner of an agricultural machine buys a factory generator that is not suitable for his walk-behind tractor.
To avoid mistakes, one very important rule should be adhered to - the selected generator for the walk-behind tractor must have power. exceeding the total number of capacities of all loads that affect the walk-behind tractor during its operation
Observance of this factor when choosing a generator will allow the unit to operate stably under a voltage of 12 Volts, eliminating the risk of a short circuit or sudden voltage surges.
Farmers often buy and install car generators on their walk-behind tractors. This solution fully justifies itself only if the farm uses a heavy walk-behind tractor with high power. For light and medium-sized agricultural units, it makes no sense to purchase such generators due to their high cost.
Installing a generator and a walk-behind tractor with your own hands takes a lot of time, but by spending it, you will ensure the smooth operation of your agricultural machine. It is necessary to connect the generator to the unit in accordance with the electrical diagram, which contains and describes all the connections necessary for installation.
In order to exclude errors at the project stage, it is necessary to pay attention to the design of the purchased motor, as well as its electrical characteristics: power consumption, supply voltage value, rotor speed. Asynchronous machines are reversible
