All about the cultivators "Neva"

Motor-cultivators "Neva" are reliable assistants for summer residents and farmers. Such durable units are used not only for land cultivation, but also for other types of work. We will consider the design features of such a technique and its area of ​​application.

Motor-cultivators "Neva" are equipped with gasoline engines of world manufacturers (Honda, Subaru, Robin-Subaru, Briggs & Stratton) with a capacity of up to 7 liters. with., thanks to which various attachments are set in motion, which will facilitate the processing of hard soils and soils of high complexity in the garden or in the garden. To cultivate soil, mow hay, transport goods or perform other types of work, various attachments can be installed on the cultivator: plows, hillers, potato diggers, lug wheels, wheels, carts, mowers, cutters for soil cultivation and the like. The use of a cultivator for agrotechnical work will be very justified at ambient temperatures of -5 - +40 C (although there are reviews from owners who claim that they worked with Neva cultivators at temperatures of -30 C).

The complete device of the Neva motor cultivators is shown in the following diagram.

The principle of operation of the cultivator is to transfer torque from the motor to the chassis. In addition, it is possible to launch rotary devices on an attached landing. To control the unit, there are handles on which the throttle, clutch and gear levers are attached.

It is accepted to classify motoblocks according to the following characteristics.

• Gasoline devices suitable for work in different areas depending on the engine power. Such units are equipped mainly with a two- or four-stroke engine. Moreover, a four-stroke engine has an increased service life (compared to a two-stroke), runs on fuel with a high octane number (AI-92 or AI-95) and does not need to mix oil with gasoline.
• Electric walk-behind tractors - use, as the name implies, electric motors for processing small areas or enclosed spaces, due to the inability to use gasoline models. These cultivators are usually lightweight and compact. Despite the light weight, the good weight distribution has helped the electric cultivators to have good stability, which makes them easier to work with.

There is also a classification by the weight of the structure.

• Devices weighing up to 30 kg (mini-cultivators). Such units are compact and mobile, have relatively low power. Suitable for a summer residence with a small area (~ 15 acres).
• Units weighing from 30 to 60 kg, the power of the engines installed on them can reach up to 5 liters. with., this allows them to be used on large areas with any type of soil: whether it is unplowed land or already plowed fields.
• Devices weighing up to 100 kg or more, equipped with engines with a capacity of 8 liters. with. and more. Such devices are suitable for the processing of hard soils and soils of high complexity in areas of a large area.

Next, a list of popular models of the Neva brand will be shown.

Has a large number of modifications. The main difference between them is the model of the installed engine. The Neva MK-200 is equipped with one of the engines of Subaru, Robin-Subaru, Honda and Briggs & Stratton. The markings in the model name indicate which engine is installed. For example, Robin Subaru engines are labeled using the Latin letter C, and the number indicates the power of the installed engine (for example, 5.0 indicates power of 5 hp). This model is equipped with a gearbox for 3 gears (2 forward and 1 reverse), their switching is carried out by a mechanism mounted on the steering wheel and a gear-chain reducer. Due to the use of aluminum alloys in the details of the case, the design came out light (58 kg). Adjustable handlebars allow you to adjust the steering wheel to suit the owner.

Despite the lower power of the Robin-Subaru four-stroke engine (5 HP), this unit has an extended configuration, which includes:

• coupling;
• plow;
• hiller;
• flat cutter;
• lugs;
• potato planter.

Due to the gear reduction transmission, this model has only one forward gear and no reverse gear. The relatively low weight (51 kg) can be compensated by additional weights mounted on the front stand. This model also features three-position adjustable handlebars.

It is distinguished by its lightness (44 kg), it is equipped with a 5-liter Briggs & Stratton engine. with. has in stock great technical capabilities for a relatively low cost. Despite the fact that the transmission consists of a gear chain reducer, the device has only one gear for forward movement. There is no gear for reverse movement, but considering the weight of the machine and the low center of gravity, the control of the cultivator should not cause any particular problems. The handle also has an adjustment property in three positions.

This unit weighs 70 kg and has compact dimensions, which did not affect its performance in any way. Powered by a 6.5 HP Briggs & Stratton four-stroke engine. with., thanks to this, the cultivator can work on difficult, sandy or clay types of soils. The transmission contains a gear-clutch aluminum reducer and a gearbox with three gears (two for forward movement and one reversible). The model has a handlebar adjustable in two positions.

This model contains good maneuverability, economy and low weight (50 kg). Installed a four-stroke Kasei 168F engine with a capacity of 5 liters. with. and is designed for working with a wide variety of soils, in small areas. The transmission contains a chain reducer and a gearbox with two gears (one for forward and one for reverse).

Motoblocks "Neva" have a fairly wide range of attachments.

• Cutters. This type of equipment comes as a component with the main part of cultivators and is used for loosening the soil. With their help, the upper soil layer is interfered, thereby improving productivity.
• Plow. In order not to damage the cutters when working with soils that contain stones or roots or similar obstacles, you can replace them with a plow. Plows are often used to cultivate uncultivated land.
• Hay mower. Quite a worthwhile device for solving the hay issue. When purchasing a cultivator in a set, the company provides an opportunity to purchase rotary mowers, which, due to knives made of durable steel, “cut” the grass and do not break when stones, roots and the like hit.
• Potato diggers and potato planters. Motoblocks "Neva" have the ability to plant and dig potatoes, which is a very useful ability for a farmer who has large plots with this crop at his disposal.
• To move smoothly on dirt roads, cultivators are equipped with rubber wheels... If these wheels are not enough, then you can buy lugs, which, due to metal plates, can move on viscous soil.
