Mower for walk-behind tractor "Neva"

Motoblocks "Neva" are today one of the most popular and widely used types of agricultural equipment for home and farming. A rotary mower for a walk-behind tractor is often used as an attachment installed on this unit. This type of device consists of a support mechanism and several rotating disks equipped with special blades. This design is highly reliable and easy to use, and is also most preferred for intensive and safe work.

Varieties and device

Depending on the design features of the mower, there are two types: rotary and segment.

Rotary mower for walk-behind tractor

Rotary

For these mechanisms, disk devices act as working elements. They are quite productive and absolutely safe during operation. The rotary mower for the Neva walk-behind tractor is capable of laying cut plants in even rows, which makes their subsequent drying much easier and eliminates the need to use forks and rakes. A unit of this type is used for mowing vegetation on roadsides and slopes, as well as for removing grass in private courtyards and estates. Rotary mowers can be single-disc or double-disc. They are attached to the walk-behind tractor at the front of the device. How are their activities carried out? Torque from a running engine is transmitted to the power take-off shaft, which in turn interacts with the working parts through a V-belt. Further, under the influence of centrifugal force, the disc legs come into contact with the surface of the grass and cut it. To protect the discs from stones and hard objects, the design of the unit provides protective covers.

Segment mower for walk-behind tractor

Segmental

Segment-type mowers are devices that include a frame and cutting components (pins) connected to each other by special fasteners. The principle of operation of such a unit is similar to the operation of classic scissors: one part of the mechanism is stationary, and the other makes linear movements - left and right. When the torque from the walk-behind tractor is transmitted to the mower, translational vibrations of the scissors occur and the plants that fall between their fingers are quickly and accurately cut. Thanks to the rational form of the device, vegetation is placed on both sides of the unit. The result is uniform windrows that will require additional tools such as forks and rakes to remove. The segment mower for the Neva walk-behind tractor is capable of operating in areas with complex terrain when mowing grain and grass crops. The displacement of the working component of the mower in relation to the walk-behind tractor can be about 20%.

Design and principle of operation of mowing machines

For dense or thick grass, use a hay mower, which is included in the attachments for walk-behind tractors. The choice of mower depends on the following factors:

• terrain, including its relief;
• the nature of the grass stand;
• financial opportunities;
• features of the walk-behind tractor and its characteristics;
• power of technology.

Important! To work with a mower, you need a powerful walk-behind tractor that can provide performance for attachments. For most units on the market, their own mowers are sold from the manufacturer. On some walk-behind tractors, for example, Neva, you can install any type of mower, including homemade ones.

Hay mowers are used to cut grass and remove weeds. A typical device includes a mowing mechanism, which depends on the type of mower, an adapter if necessary, a hitch, and fasteners. It is worth considering that oil must be supplied to the rotating fragments.

Rotary mowers and their prices

We recommend buying a rotary mower for farmers who need to mow dead wood with a diameter of less than 100 mm, dense vegetation or hard remains of sunflower or corn. But the rotary model can also handle cleaning a lawn or a small area in the garden. It is mounted to the drive of the Neva walk-behind tractor from the front or by a trailed method. Trailed ones mulch grass, so they are not suitable for farmers who need to harvest grass for hay.

The operation of the rotary mower is carried out from the belt shaft of the walk-behind tractor. Suitable for petrol and diesel Neva walk-behind tractors, as in the video. For attachment to the latter, a special adapter is included in the package. Among the various rotary mowers for the Neva, the Kaluga Zarya and the St. Petersburg KR-05 stand out. Depending on the modification, rotary mowers have 1-2 working discs, KR - 05 has working body 1, Zarya has 2 discs. There are 4 knives attached to the disk using a movable hinge joint. When the disc moves, the movable cotter pin allows the knives to turn under the influence of centrifugal force and they cut the grass. At Zarya, the discs rotate towards each other, the lawn cultivation width is greater. The design of the rotary model is located on a special slide; they allow you to adjust the height of the grass cut with a simple movement. The mown vegetation is distributed in even shafts on both sides and is easy to collect with a pitchfork.

Working with a rotary mower is simple, but once a day you need to unscrew the corner joints and lubricate the gears with lithol or machine oil. Equipment will last longer with proper care.

Let's take a closer look at the popular segment models for the Neva walk-behind tractor in video and photos. In the video below you can see how the equipment works in the field and along the road.

Rotary "Zarya"

The official manufacturer of the Zarya rotary mower, Kadvi, is located in Kaluga. But there are many home-made and Chinese models on the market, made according to the designs of the manufacturer “Kaluga Engine”. Externally, they differ only in color - the Kaluga Zarya is bright red, as in the video. But this is not the main difference. The Chinese ones have worse quality, as they use low-quality material for production.

User reviews of the Chinese-made Zarya are mostly negative. The model needs to be sorted out before work, there is not enough lubrication, there is not enough oil in the gearbox. Positive reviews about the Chinese “Zarya” are associated with the high quality of the gear. It lasts for more than 3 years and does not wear out. In domestic models, signs of wear appear after 2 years.

The official "Zarya" for the "Neva" walk-behind tractor has proven itself to be used well. Chinese and homemade mowers are just fakes, although among them you can find models of acceptable quality.

Characteristics of the Zarya mower for the Neva walk-behind tractor and the price of analogues and licensed equipment in the table:

You can buy cheaper directly from the manufacturer in Kaluga. The retail price is 10-15% higher and it is more profitable to buy in bulk. Spare parts from the domestic model are suitable for all Chinese analogues, therefore, in some cases, you don’t have to overpay. The price for used equipment starts from 5,000 rubles, but we do not recommend purchasing equipment older than 10 years.

Rotary mower KP -05

Officially, KP-05 is produced in St. Petersburg at the Red October plant. The model is official for the Neva walk-behind tractor MB-1 and MB-2. It is impossible to find exact analogues on the market, but there are similar mowers of low quality. Many years of experience and advanced technologies allowed the manufacturer to develop an optimal, functional and small rotary mower KP-05. The reader can see the model in action in more detail in the video .

The weight of the equipment is less than that of the Zarya model, so the KP-05 is convenient for summer residents and farmers with small personal plots. Copes with any remains of cultivated plants, shrubs, hard and thick grass. The baby has enough power to cope with tough vegetation.

KP-05 is used on uneven surfaces, since the working body in the form of a large disk easily adapts to any unevenness. The mower is not afraid of small stones and branches. There is a metal casing around the disc that protects the operator from small particles of stones and vegetation.

Advantages and disadvantages

The advantages of rotary mowers include the following factors:

• excellent level of performance;
• simplicity of design;
• comfort in use;
• high degree of security;
• excellent reliability of mechanisms;
• long period of operation;
• reasonable cost.

These units were not spared their negative aspects. These include such disadvantages as low speed, unstable operation at low engine speeds and poor protection of the device from stones.

Segment mowers for Neva equipment and their prices

The segment model is mounted to the Neva walk-behind tractor MB-1 and MB-2 at the front. Suitable for diesel and gasoline belt models, as well as mini tractors with a similar connection system.

Segmented models are more powerful and cope with the most overgrown areas. If you move at the stated speed no faster than 2-4 km/h, then the lawn will be smooth without gaps.

The working bodies of the segment model work according to the principle of scissors - progressively. They come into motion under the influence of the drive shaft of the Neva walk-behind tractor. The thickness of dead wood should not exceed 110 mm, the working width should not be less than 1 m.

The most popular model for MB 1 and 2 is KN-1.1. The segment technique is convenient in that the working surface follows the surface of the soil when moving. You can adjust the height of the mowed grass using special slides.

The segmental equipment is not afraid of small stones and anthills, therefore it is suitable for forestry for leveling areas along roads.

Technical characteristics of the KN-1.1 segment mower for the Neva walk-behind tractor MB-1 and MB-2 are presented below:

It is more profitable to buy from official dealers. The price of analogues from Chinese manufacturers is lower, but the quality is worse. It is easy to attach to the walk-behind tractor using a special pin.

The price is directly related to the quality of the equipment, so it is better to buy an official model for your site.

There are two types of mowers that can be installed on a walk-behind tractor - rotary and segment. They differ only in the operating principle. Both have their merits; it is impossible to say unequivocally which is better. It all depends on the goals and characteristics of your site.

Rotary

It consists of a frame on which discs with cutting elements are installed; the number of discs varies, usually two or three. On the side of the frame there are slides through which the height of the grass cut is adjusted. The operation of the rotary mower is ensured by the walk-behind tractor using a transmission while driving.

The number of knives determines the performance; the more there are, the higher the speed, but when choosing, you need to start from the characteristics of your motor cultivator, namely its power.

According to the methods of aggregation with a walk-behind tractor, mowers are divided into groups:

• trailed, or frontal, it is located in front of the walk-behind tractor;
• hinged, or rear, it is attached to the back;
• semi-trailer, it is installed on the side.

The main advantage of a rotary mower for a walk-behind tractor is its ease of operation; almost anyone can operate it, while complete safety is ensured.

Such mowers are manufactured mainly in Russia and China, they are almost identical, although the reliability of domestic products is higher and they require less care and maintenance.

Segmental

This mower operates on slightly different principles. On the frame, which is its basis and mounted on wheels, there are cutting knives. The blades move back and forth to remove grass and plants that fall between their edges. Height adjustment is made using a slide.

The performance of such mowers is slightly higher, the degree of uniformity of mowing is almost the same, however, more care is required during operation so as not to hit an obstacle. Mown grass is laid in rows that are easy to collect; this function is included in a yard of models produced for specific types of basic walk-behind tractors.

Reviews

Comments left by mower users are replete with the following excerpts:

1. There is a scythe available for the Neva “KN 1” walk-behind tractor. The unit is fast and powerful, there are no problems with spare parts, overall I am happy with the machine. Before this, there was a Chinese analogue, which had to be constantly adjusted and repaired. Eventually its working parts became loose and its main mechanical parts collapsed. And “KN 1” still never ceases to please. Its feature is the ability to work effectively on uneven and bumpy terrain. While moving, the mower follows the uneven terrain and makes the grass cut quite clean.
2. I am the owner of a mounted rotary mower for the KR 05 walk-behind tractor. The unit is well suited for mowing dense vegetation and dead wood. I use it mainly for clearing the fields of corn and sunflower residues. If you go over the same area twice, the bevel turns out to be almost perfect. It is quite simple to assemble a mower with a walk-behind tractor; for this you need to connect the drive with the working elements and secure the device in the front part of the structure. Using the mower is comfortable and easy. In order for the unit to serve for many years, it is necessary to carry out proper care and systematic maintenance.

Dmitry I’ve been using the rotary mower for 3 seasons. It works pretty well. I mow, though not much - about 1 hectare per season. If the drive belt and motor of the walk-behind tractor are good, then anthills will fly past your head (it is advisable to have time to dodge), and freely cut off trees as thick as your finger. Among the disadvantages is strong vibration on the steering wheel of the walk-behind tractor (your hands tingle for a long time like needles after a long mowing), as well as When the ground is uneven, the belt pulls out quickly. Without a trailer for riding, I think it will be easier to work. If the grass gets full, it can be shaken off quickly. But a mower with a blade blade will cut a little lower, but it needs a more even terrain. But for the price and performance, personally For me, there is no alternative yet.

Leonid Mower Zarya has been working for me for 3 years. I still have a set of spare knives lying around. I immediately removed the knives and sharpened them with sandpaper, the angle was less than 45 degrees. and instead of cotter pins, he inserted nails, biting them along the length and bending them. I sharpened it without removing it - with a grinder. Sharp knives reduce the load and cut short grass better. There were no problems with gearboxes and belts. And you can check the lubricant in order to sleep peacefully.

Dmitry Panchenko My Rotarka is already 12 years old, I’m very pleased. I installed segments from the combine, after minor modifications. It mows everything down, and also settles it in a rare manner. If something happens, you can quickly change the segment in the field, it doesn’t take much time. With dense grass, it does not clog like segmented grass. In a word, very pleased. Unfortunately, there are no photos, I’ll try to post them in the summer when haymaking starts.

Price

You can buy a new Zarya mower from an official dealer for 11.5 -12.0 thousand rubles. A used unit will cost about 6.0 -7.0 thousand rubles. The mower for the KR 05 walk-behind tractor will cost the buyer 14.0-14.5 thousand rubles. The cost of the option with operating time will be about 7.0-8.0 thousand. Those wishing to purchase a new segment-type model “KN 1” will have to fork out 18.5-19.0 thousand.

Having examined the main types of mowers for the Neva walk-behind tractor, we can conclude that each representative of one or another model range meets the basic needs of owners of farms and private farmsteads. However, we should not forget that all units have not only a number of advantages, but also a series of disadvantages. Therefore, when choosing a specific device option, you must rely solely on your own taste and be guided only by personal preferences.

The rotary mower for walk-behind tractors is highly reliable and easy to use, and is also most preferable for intensive and safe work.
