Rotary mower "Dawn": reviews, specs

On large farms for hay makingand cleaning the fields from the weeds of a gasoline or ordinary braid may not be enough. The "Zarya" mower will help optimize and accelerate the process. It is provided for use with different types of motor blocks, 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 feedback from users.

Manufacturer

The mower "Zarya" is produced by the subdivisionKaluga Turbine Combine, established in 1966. The product range of the plant includes turbine engines, power plants, as well as a wide range of mass-produced products. The engine with one cylinder type DM-M1 is operated on various machines, motor pumps, household devices, agricultural blocks. For the latter, a number of attachments are provided, including mowers.

Device

There are two modifications on the market: mower "Dawn" and "Dawn-1". The first variant is divided into the model KR.05.000 (designed for operation with motor blocks produced by KADVI LLC) and KR.05.000-03 (the variation is intended for machinery from other manufacturers).

The attached implements aggregatewith the majority of domestic motoblocks. The principle of the mechanism is cutting the grass with a pair of knives placed on the discs. The elements are fixed freely on the cotter pins, under the action of the centrifugal force they protrude beyond the edges of the disk during rotation, taking the working position.

It should be noted that for connectionadaptations to motoblocks of different designs, there are several variations of the mowers differing by the pulley drives and the size of the tensioner. The main interaction is carried out through a knot with a belt. The mower "Zarya-1" is designed for aggregation with the output shaft of the PTO equipment of the "Ugra" type. Interaction is made through a regular or additional gearbox. The modification has a low weight, which facilitates its connection to the motor block. In addition, there is an option to adjust the height of the mowed grass.

Technical plan parameters

Below are the characteristics of the rotary mower "Dawn KR.05.000". The parameters for KR.05.000-03 and "Zari-1" are indicated in brackets:

• The power rating of the motor block is 5 (7/6) horsepower.
• The grip width - for all models it is 80 cm.
• The working maximum speed is 4 (4/3) km / h.
• The cutting height is 7 (7/10) cm.
• The height of the processed grass to the maximum - for all modifications of 1 m.
• The productivity is 0.2 (0.15 / 0.2) ha / hour.
• The speed is 2400 (2400/2635) revolutions per minute.
• The length is 80 (81 / 49.2) cm.
• The width is 93 (93/84) cm.
• Height - 54 (78/43) cm.
• Weight - 31 (33/28) kg.

Features

As you already understood, you can connect the rotarymower "Dawn" to the motor block. The unit has a number of features. Its design is practical and simple. Technique confidently and efficiently mows various kinds of grasses, including cereals with a thick stem up to 10 mm in diameter. The belt drive interacts with the working part by connecting it to the pulley of the power take-off shaft or direct connection to the engine ("Zarya-1").

The freely fixed knives enableweaken the influence of unevenness of the soil on the result of the work. In addition, this design allows obkashivat sites with moleholes, dense edges and roots. As a safety device, in case of hitting a rigid obstacle, a system of spot welding fasteners is provided, which breaks off at a load above the norm, which protects the mechanism from damage.

Advantages and disadvantages

The main advantage of the rotarymower "Dawn" (for the motor-block "Neva" and its analogs) is the possibility of folding the mown hay into neat rolls. 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, since it has protective fuses. However, you should not forget about security measures, you should not allow any contact with discs and cutting knives when the state is on.

The disadvantages of this mower are fast wearbelt drive. This is due to the fact that when working sections with different terrain the working part of the device has some freedom of movement in relation to the motor block. This leads to a violation of the coaxial position of the drive pulley and the motor, which contributes to the acceleration of belt wear and deformation. Having the necessary skills, you can adapt a more rigid connection, without losing the possibility of free movement of the working unit.

Zarya-1

The drawbacks of this model are highlabor costs when installing on a motor-block. The mower is connected to the PTO of the rear part of the motor equipment. To do this, you need to deploy the handle 180 degrees, install the gearbox and connect a rotary mower to it. Moving the truck is done at the rear speed.

Additionally, it will be necessary to provide an opportunityactivation of increased gears while driving forward. This is necessary in order to exclude the possibility of a collision at the operator at high speed. The complexity of such operations directly depends on the structural features of the motor block and may require some manipulation to switch control drives, gearboxes and other elements responsible for controlling the machinery.

Differences between modifications

Spare parts for the mower "Zarya-1" is more durable andmore perfect. In addition, the speed of the working disks is increased (from 2400 to 2635 revolutions per minute). The weight of the apparatus was increased by 4 kg. At the same time, the new design of skis made it easier to work on uneven grounds.

The speed of mowing grass for all variationsapproximately the same and is from 2 to 4 km / h. The gripper has an identical width of 800 mm. The main difference is the way to attach to the motor block. If the "Dawn" is fixed from the front of the equipment with a pulley and tensioner, the updated version is attached by connecting to the power take-off shaft through a universal gearbox. Both units are perfectly able to cope with the tasks at private sites, in small and medium-sized farms. The equipment enables the owner to accelerate and facilitate the collection of hay, ensuring safety and accuracy during operation.

Mower "Dawn": reviews

In general, the responses of the owners of thetechnicians are positive. Some consumers improve the design by welding divisors like the combine harvester. This makes it possible to improve the processing of uneven surfaces. In "Zare-1" such alteration is not required thanks to new skis.

Still, owners change factory knives to segmentoptions. They allow you to reduce vibration and load on the steering wheel, but must be secured freely, so as not to degrade the overall functionality of the mower. Otherwise, users note the high performance of technology, ease of use and durability.

Finally

This technique is not only usedin the agrarian sphere, but also purchased for public works (removal of grass in the territory of parks and squares). The technics from the Kaluga manufacturers really replaces not only the haymaking machine, but also a lawnmower, and also a trimmer for harvesting grass. Along with reliability, "Dawn" has high productivity, can process for an hour to twenty hectare.
