Another novelty appeared on the market of mini-equipment for agriculture, which immediately began to gain consumer confidence. We are talking about the so-called hybrid walk-behind tractors, which are a successful combination of a heavy chassis with a powerful engine. Readers of this article will be the first to know about all the advantages and disadvantages of the new “hybrid”.
What is a hybrid walk-behind tractor
Currently, all walk-behind tractors can be divided into three classes – light, medium and heavy. The latter category is intended for the processing of any type of soil on large areas, as well as for carrying out other types of agricultural work – from transportation to cutting firewood. The problem is that heavy water-cooled motors are installed on such equipment, the power of which is not always enough to solve specific problems.
Therefore, first the owners, and then the manufacturers, began to install more powerful air-cooled engines on the chassis of heavy walk-behind tractors. As a result of this modification, a hybrid installation appeared, which:
- provides reliable starting in all weather conditions;
- allows you to fully unleash the potential of the gearbox;
- significantly expands the list of compatible attachments.
By the way, such a modernization of powerful walk-behind tractors can be done at home:
- We order via the Internet or buy an air-cooled engine with a capacity of 16-18 l / s in specialized stores. Preference should be given to models with a reducer. One of the best options in this case would be a brand power plant.
- If the motor does not have a reduction gear, it can be replaced with a homemade pulley. However, in this case it will be necessary to calculate the dimensions of this structural element in order to level the increased speed. Well, any turner is capable of carving such a detail.
- Separately, you will need to make a special plate with holes in order to install the power plant on a factory / homemade frame.
- After that, you can proceed to the assembly of the unit. The final installation of the hybrid installation, excluding the time of the preparatory phase, does not take more than an hour.
With the story of the birth of a new “hybrid” seems to have figured out. It’s time to move on to discussing the specific pros and cons of this mini-technique.
Why do you need a hybrid walk-behind tractor
Let’s start with the main advantage of the novelty, which is undoubtedly increased power. Indeed, after replacing the engine, this parameter immediately changes from 10 or 12 to 16 or even 18 horsepower, which, combined with a reinforced chassis, reliable transmission, multi-speed gearbox (usually 6 forward and 2 reverse) and a powerful gearbox essentially translates such an installation into a class of tractors. At the same time, according to the owners of mini-equipment, hybrid units show the most impressive result when tilling the soil with a tiller that literally bites into any type of soil.
In addition, a hybrid installation with a 16-horsepower engine produces 3600 rpm, has a large capacity tank (from 6.5 liters), runs on gasoline (like a car) and can be equipped a battery (simplified starting). A separate article is distinguished by a large motor resource and inexpensive spare parts.
It remains to talk about another feature of walk-behind hybrid tractors, which causes a lot of controversy among the owners of such mini-equipment. The fact is that an 18-horsepower air-cooled engine weighs only 35 kilograms, and the weight of water-cooled engines reaches 100 kilograms.
Therefore, hybrid installations are much lighter. It’s a pro or a con, judging by the owners of the units. Operators will certainly appreciate the simplified control of a lightweight walk-behind tractor, including those with factory-released axle shafts.
However, when transporting goods and working with attachments, the owners of such mini-equipment may encounter a lack of grip on the surface, which will lead to the walk-behind tractor slipping or bouncing, especially at the beginning of the movement. You can overcome this inconvenience by using an additional load attached to the front of the hybrid unit.
