The mower for the Neva motor-cultivator belongs to the auxiliary equipment of the multifunctional agricultural unit Neva, which is extremely popular among summer residents and agricultural producers. This motor-cultivator is independently unproductive, but when it is mounted with a towed or mounted attachment, it makes it possible to carry out any agricultural work on the ground. Attached equipment for mowing is coupled with the drive of the motor of a cultivator, with the help of which it is driven. There are 2 basic modifications of mowers: segment and rotary.
These mechanisms are often used in large overgrown areas, as well as for mowing for harvesting straw and hay. The mower easily operates both on the plain and in territories with difficult terrain. At a unit moving speed of up to 4 km / h, the grass is cut off at the very edge, then carefully and evenly laid on the ground with rollers. The segment mower for the cultivator is characterized by excellent productivity and ease of operation. The principle of the mechanism is based on the reciprocating movements of the knives from the power drive of the cultivator. One of the segments of the mower with cutting fingers is in continuous movement (to the left and to the right), the other is static. While the grass falls between the fingers, its stalks are evenly cut.
The mower is mated and attached to the front cultivator. The design is securely mounted on wheels, on the sides of the cutting system are specialized rails for adjusting the height of the bevel.
The segment mower has the following positive qualities:
- controlled shutdown mechanism;
- lack of mechanical vibrations (vibration);
- tilt control;
- the functioning of cutting knives directly at the roots of the vegetation;
- production of knives from red-hot steel;
- wear resistance of a protective casing;
- long service life;
- availability of spare parts;
- ease of use;
- comfort in work;
In addition to the positive qualities, this device has disadvantages:
- large dimensions and weight;
- difficulties in maintenance;
- high price.
An example of such hanging equipment for motor-cultivators of the Neva trademark is the KN-1.1 installation.
Rotary Mounted Mowing Machine
The rotary device for the Neva motor-cultivator is suitable for mowing thick grass, undersized shrubs, and any solid vegetation having a diameter of not more than one centimeter. It is hung in front of the Neva motor-cultivator.
The principle of operation of the device is simple: by means of a gearbox equipped with pulleys and belt drive, the mowing machine receives torque from the engine, which spins the disks with retractable knives. In essence, everything is based on inertia. The blades under its influence function all the time while the motor of the cultivator is functioning.
The disadvantages of this modification are mainly explained by the unreliability of the power drive and its rapid wear. According to the reviews of the owners, it is especially sensitive to the structure of the grass stand: it perfectly mows legumes (for example, clover), but it functions hard on grassy areas (in particular, with a boneless fire).
For the normal functioning of the rotary mower, it is necessary that the crankshaft carry out the highest possible number of revolutions per minute. It is because of this that the grass is rolled up into rolls. In order not to “torment” the engine, the jack of all trades came up with a simple solution: install a larger diameter transmission pulley on the walk-behind tractor. In addition, when working with a rotary device, it would not hurt that the site landscape was smooth, since very often the rotor unit rests against even small obstacles (mole burrows, anthills).
The name of the fixtures may vary depending on the manufacturer, but the brand remains the same. The cost of all manufacturers is different - it depends on the materials that were used to create this model.
Rotary mower "Dawn"
The Zarya mowing machine for the Neva motor-cultivator is made in Russia and China. Domestic makes "Kaluga engine." The Chinese device has a darker color.
According to reviews by owners who disassembled the Chinese-made Dawn, a small amount of lubricant is present in the gearbox. With prolonged use (more than 3 years), traces of production on the gears do not arise from it. Therefore, in the "Dawn" of Chinese production, high-quality steel is used. But before using the Chinese version, it is better to open the gearbox and add lubricant.
We will not talk about the quality indicators of the "Dawn" of domestic manufacture. She won the hearts of a large number of users of the Neva motor-cultivator and others like him. We only note that the patent for the production of this modification is available exclusively to the Kaluga Engine, and everything else is fakes on a popular and relevant device.
This rotary mower is produced by the manufacturer of the Neva motor-cultivator - Krasny Oktyabr (city of St. Petersburg). It was created directly for this type of cultivator. Prototypes and other manufacturers of such attachments simply do not exist. This is a rather small-sized sample with a mass less than that of a 2-disk mowing machine. It is suitable for gardeners and people who have small-sized areas for mowing. The equipment is pretty mobile. Neither stones, nor anthills, nor thick branches are afraid of the device. The spit is quite powerful and can be controlled even with very neglected areas. In addition, the device is used for mowing crops and single bushes.
The structure of the model includes one large disk. She moves effortlessly on the ground and easily mows grass in the most inaccessible places.
Segment mowing machine for Neva KN-1.1 motor-cultivator
Such a mower is intended for motor blocks of the MB1 and MB2 models. This mower is used to mow grass for cattle feed. During operation, the mower does not crush the grass and places it in even rows. It is managed in inaccessible wooded and boggy areas. This sample is made at many enterprises of the Russian Federation.
Choosing an attachment for haymaking by means of the Neva MB 2 motor-cultivator and using it as a lawn mower, it is necessary to take into account:
- view and landscape of the territory;
- grass stand structure and its changes;
- own material capabilities;
- possibilities of a cultivator in the matter of installing mounted equipment;
- necessary engine power.
Rules for working safely with mounted mowers
When operating the unit of any kind (rotary or segment), it is extremely important to adhere to safety regulations.
- Before starting work, it is required to check the serviceability of all fasteners and connections;
- it is forbidden to be in front of the cutting device during operation;
- stop using the unit if a problem occurs;
- all repair and technical operations should be carried out exclusively with the engine of the device turned off;
- Inspect the belt tension and tightening the nuts every 2 hours of the duty cycle;
- Do not exceed the maximum permissible speed - the mowing will turn out to be of low quality;
- turn off the drive of the mowing machine during its transportation;
- be careful not to allow contact with the cutting components of the unit when moving or lifting it.
