On large farmlands, a gasoline or conventional scythe may not be enough to make hay and clear weeds from fields. The Zarya mower will help optimize and speed up the process. It is intended for use with different types of walk-behind tractors, it is available in several modifications that differ in the type of fastening and some structural elements. Consider the characteristics and features of these devices, as well as user reviews.

Manufacturer

The Zarya mower is produced by a division of the Kaluga Turbine Plant, established in 1966. The product range of the plant includes turbine motors, power plants, as well as a wide range of products for mass use. The engine with one cylinder type DM-M1 is operated on various machine tools, motor pumps, household appliances, agricultural blocks. A range of attachments are available for the latter attachments, including mowers.

Device

There are two modifications on the market: the Zarya and Zarya-1 mowers. The first option is subdivided into model KR.05.000 (designed for operation with walk-behind tractors manufactured by KADVI LLC) and KR.05.000-03 (a variation is intended for equipmentfrom other manufacturers).

The attachments under consideration aggregate with most domestic walk-behind tractors. The principle of operation of the mechanism is to cut grass by means of a pair of knives placed on disks. The elements are freely fixed on cotter pins, under the action of centrifugal force during rotation they protrude beyond the edges of the disk, taking the working position.

It is worth noting that for connecting the device to motoblocks of different designs, there are several variations of mowers that differ in pulley drives and tensioner sizes. The main interaction is through a knot with a belt. The Zarya-1 mower is designed for aggregation with the PTO output shaft of the Ugra-type equipment. Interaction is made through a regular or additional gearbox. The modification has a low weight, which facilitates its connection to the walk-behind tractor. In addition, there is an option to adjust the height of the cut grass.

Technical plan parameters

Below are the characteristics that the rotary mower "Zarya KR.05.000" has. Parameters for KR.05.000-03 and Zarya-1 are indicated in brackets:

• The power indicator of the walk-behind tractor is 5 (7/6) horsepower.
• Capture in width - for all models it is 80 cm.
• Maximum working speed – 4 (4/3) km/h.
• The cutting height limit is 7 (7/10) cm.
• The height of the processed grass to the maximum - for all modifications 1 m.
• Productivity - 0, 2 (0, 15/0, 2) ha/hour.
• RPM - 2400 (2400/2635) rotations per minute.
• Length– 80 (81/49, 2) see
• Width – 93 (93/84) cm.
• Height – 54 (78/43) cm.
• Weight - 31 (33/28) kg.

Features

As you already understood, you can connect the Zarya rotary mower to a walk-behind tractor. The unit has a number of features. Its design is practical and simple. The technique confidently and efficiently mows various types of grasses, including crops with thick stems up to 10 mm in diameter. The drive on the belt interacts with the working part by connecting it to the power take-off shaft pulley or directly connecting it to the engine (“Zarya-1”).

Loosely fixed knives make it possible to reduce the effect of uneven ground on the final work. In addition, this design allows you to mow areas with wormholes, dense edges and roots. As a fuse, in the event of a hard obstacle, a system of spot welding clamps is provided, which break off when the load is above the norm, which protects the mechanism from damage.

Pros and cons

The main advantage that the Zarya rotary mower has (for the Neva motoblock and analogues) is the ability to fold mowed hay into neat windrows. The function greatly facilitates further processing. In the presence of too thick grass, this approach increases the drying time. The tool in question is safer than cutting modifications because it has protective fuses. However, you should not forget about safety measures, you should not allow any contact with discs and cutting knives whenon.

The disadvantages of this mower include rapid wear of the drive belt. This is due to the fact that when processing areas with different terrain, the working part of the device has some freedom of movement in relation to the walk-behind tractor. This leads to a violation of the coaxial position of the drive pulley and the motor, which contributes to accelerated belt wear and deformation. With the necessary skills, it is possible to adapt a more rigid connection without losing the possibility of free movement of the working unit.

Zarya-1

The disadvantages of this model include high labor costs when mounted on a walk-behind tractor. Structurally, the connection of the mower to the PTO of the rear part of the motor equipment is provided. To do this, you need to turn the handle 180 degrees, install the gearbox and connect the rotary mower to it. The walk-behind tractor is moved at reverse speed.

Additionally, it will be necessary to ensure the possibility of activating high gears when moving forward. This is necessary in order to exclude the possibility of collision with the operator at high speed. The complexity of such operations directly depends on the design features of the walk-behind tractor and may require some manipulations to switch the control drives, gearboxes and other elements responsible for controlling the equipment.

Differences between modifications

Spare parts for the Zarya-1 mower are more enduring and more perfect. In addition, the rotation speed of working disks has been increased (from 2400 to 2635 rotations per minute). WeightThe device has grown by 4 kg. At the same time, the new ski design made it easier to work on uneven ground.

The grass mowing speed is approximately the same for all variations and ranges from 2 to 4 km/h. The grip has an identical width - 800 mm. The main difference is the method of attachment to the walk-behind tractor. If the Zarya is fixed from the front of the equipment using a pulley and tensioner, then the updated version is attached by connecting to the power take-off shaft through a universal gearbox. Both units perfectly cope with the tasks set on private plots, in small and medium-sized agricultural enterprises. The equipment allows the owner to speed up and facilitate the process of collecting hay, ensuring safety and accuracy during operation.

Mower "Dawn": reviews

In general, the feedback from the owners of the equipment in question is positive. Some consumers improve the design by welding dividers like a combine harvester. This improves the processing of uneven surfaces. In Zarya-1, such a rework will not be required thanks to the new skis.

The owners also change factory knives for segment options. They reduce vibration and load on the handlebars, but must be loosely fastened so as not to impair the overall functionality of the mower. Otherwise, users note the high performance of the equipment, ease of use and durability.

In closing

The equipment in question is operated not only inagricultural sector, but also purchased for public works (grass removal in parks and squares). Equipment from Kaluga manufacturers really replaces not only a hay harvester, but also a lawn mower, as well as a grass trimmer. Along with reliability, "Zarya" has high productivity, is able to process up to twenty acres in an hour.
