Motoblocks that have a power take-off shaft in their functionality, as a rule, are in price from experienced summer residents. The presence of such a unit makes it possible to use different tools in the country. The use of additional equipment will undoubtedly have a positive effect on the quality of the crop.

Main PTO functions

First of all, you need to know that the power take-off shaft is a device for transferring engine energy to the moving elements of the tool or mechanisms working in conjunction with the walk-behind tractor. In machines, in most cases, the drive mechanism of the agricultural implement is connected to the power take-off shaft using a splined sleeve. This connection method significantly increases the reliability of the mechanisms and increases their service life.

Most of the entire range of units is equipped with a shaft that is installed at the rear of the walk-behind tractor. But sometimes there are agricultural machines equipped with a PTO located on the front side of the unit.

Let's list the tasks that the power take-off shaft performs

• Launching and functioning of attachment mechanisms. It is worth noting that equipment units can be driven both directly and using belt drives, gearboxes or cardan shafts. From the connection principle, the degree of load on the mechanism changes.
• Sometimes the PTO shaft can be useful for trailer hydraulic systems. In this case, the shaft acts directly on the hydraulic pump. But for such functions, the PTO is rarely needed, because summer residents very rarely use tools with hydraulic systems.

The ability to implement the described tasks made walk-behind tractors with a power take-off shaft very popular among owners of large summer cottages.

Classification

Power take-off shafts are divided into classes depending on their operating principle. Considering this nuance, then all mechanisms can be divided into several types.

• Shafts that work directly from the engine of the walk-behind tractor are called dependent. If there is no connection between the clutch and the engine, the PTO stops rotating.
• In the independent version, the power take-off shaft works in a more gentle mode due to the even distribution of the load. This type of drive makes it possible to use the mechanism with the clutch disengaged.
• If the non-stop operation of the PTO is provided by the rotation of the wheels, then such a shaft is called synchronous.
• Asynchronous shafts, according to the principle of operation, are the opposite of the mechanism of the previous class. These types of assemblies are usually designed for an implement that must operate intermittently and at low speeds.

This kind of division by class will allow the owner to choose a walk-behind tractor with a PTO of a suitable type. Although, if necessary, a different type of shaft can be purchased separately and installed by yourself.

How to choose a walk-behind tractor?

Before purchasing the unit, you must focus on the complex of operations that the walk-behind tractor will have to perform. You should not buy the most expensive modifications of units that have a full set of functions in their arsenal .… Not every model will be able to cope with the task at hand.

For example, in large areas with a dense soil composition, the best option would be to buy a heavy unit, while in a small dacha a light-class walk-behind tractor will be enough.

And also, when choosing, it is necessary to decide on the type of fuel on which the agricultural machine will work. Units with a gasoline engine are quieter, lightweight and easy to maintain. Diesel walk-behind tractors are noisier, but they take up with their high power. The downside of a diesel engine is its high price.

It should be borne in mind that additional attachments can often be supplied by another manufacturer … In this case, to connect the implement to the purchased walk-behind tractor an adapter is required … This can lead to unit malfunction or work problems.

On the market today, the range of motoblocks is quite diverse. Models of such companies as Husqvarna, Profi, Hyundai are in great demand .… In our country and neighboring countries such machines as "Belarus", "Neva", "Salyut-100" are presented. Of course, one should not discount the Chinese firms Forte and Wiema, because their products are also quite in demand.

If we compare foreign models with domestic counterparts, then we can see that their cost is not always justified by the reliability and ease of use. Besides imported models will require expensive consumables and the availability of experienced service technicians. Both are very difficult to find.

Domestic firms are focused on ease of use, low cost. The decisive factor is the ability to repair the walk-behind tractor on your own.

Model overview

In order to get some idea about motoblocks with a power take-off shaft, you need to familiarize yourself in more detail with the characteristics and features of some models.
