On large farmland, hay weeding and clearing the fields of weed gasoline or ordinary scythe may not be enough. The Zorya 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, differing in the type of attachment 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 Works, established in 1966. The plant's product range includes turbine engines, power plants, as well as a wide range of mass-use products. The engine with a single cylinder of the DM-M1 type is operated on various machines, motor pumps, household appliances, agricultural units. A number of attachments are provided for the latest fixtures, including mowers.
Device
There are two modifications on the market: the Zarya and Zarya-1 mowers. The first option is divided into the model .05.000 (designed for operation with motor blocks produced by LLC KADVI) and .05.000-03 (the variation is intended for equipment from other manufacturers).
The considered attachment aggregates with most domestic walk-behind tractors. The principle of the mechanism is to cut the grass with a pair of knives placed on the discs. Elements are fixed freely on cotter pins, under the action of centrifugal force during rotation, they protrude beyond the edges of the disk, assuming the working position.
It is worth noting that for connecting the device to motor blocks of different designs, there are several variations of mowers, differing in pulley drives and tensioner sizes. The main interaction is through a node with a belt. The Zarya-1 mower was designed for aggregation of the Ugra-type equipment with the PTO output shaft. Interaction is made through a standard or additional gearbox. The modification is lightweight, which facilitates its connection to the walk-behind tractor. In addition, there is an option to adjust the height of the mowed grass.

- Length - 80 (81 / 49.2) cm.
- 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 the 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 herbs, including crops with a thick stem with a diameter of up to 10 mm. The belt drive interacts with the working part by connecting it to a power take-off pulley or directly connecting it to the engine ("Zarya-1").
Freely fixed knives make it possible to weaken the effect of uneven soil on the result of 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 that breaks when the load is above normal, which protects the mechanism from damage.
Pros and cons
The main advantage that the Zarya rotary mower has (for the Neva motoblock and its analogues) is the possibility of folding the mown hay into neat rolls. The function greatly facilitates further processing. If there is too thick grass, this approach increases the drying time. The tool in question is safer than ringworm modifications, since it has protective fuses. However, security measures should not be forgotten, any contact with the blades and cutting knives should not be allowed when the condition is on.
The disadvantages of this mower include quick wear of the drive belt. This is due to the fact that when processing areas with different reliefs, the working part of the device has some freedom of movement with respect to the walk-behind tractor. This leads to a violation of the coaxial position of the drive pulley and the motor, which helps to accelerate the wear of the belt and its deformation. Having the necessary skills, you can adapt a more rigid connection, without losing the possibility of free movement of the working unit.
"Dawn-1"
The disadvantages of this model include high labor costs when mounting on a walk-behind tractor. Structurally, the mower is connected to the PTO of the rear of the motor equipment. To do this, you need to turn the handle 180 degrees, install the gearbox and connect a rotary mower to it. Moving the walk-behind tractor is done at reverse speed
In addition, it will be necessary to provide the ability to activate overdrive when moving forward. This is necessary in order to exclude the possibility of a 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 control drives, gearboxes, and other elements responsible for controlling the equipment.
Differences between modifications
Spare parts for the Zarya-1 mower are more durable and perfect. In addition, the speed of revolutions of working disks has been increased (from 2400 to 2635 rotations per minute). The mass of the device has increased by 4 kg. At the same time, the new ski construction made it easier to work on uneven grounds.
The grass mowing speed for all variations is approximately the same and ranges from 2 to 4 km / h. The gripper has an identical width of 800 mm. The main difference is the method of attachment to the walk-behind tractor. If the "Dawn" is fixed from the front of the equipment using a pulley and a tensioner, then the updated version is attached by connecting to the power take-off shaft via a universal gearbox. Both units perfectly cope with the tasks set in private plots, in small and medium-sized agricultural enterprises. The equipment enables 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 technology in question is positive. Some consumers improve the design by welding dividers like a combine header. This allows you to improve the processing of uneven surfaces. In “Dawn-1” such alteration is not required due to new skis.
Even the owners are changing factory knives to segment options. They allow you to reduce vibration and the load on the steering wheel, but must be fixed freely 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.
Finally
The equipment in question is operated not only in the agricultural sector, but is also purchased for public works (removing grass in parks and squares). The equipment from Kaluga manufacturers really replaces not only the hay machine, but also the lawn mower, as well as the grass trimmer. Along with reliability, “Zarya” has high performance, is able to process up to twenty hundred parts per hour.
