The rotary mower is what every farmer needs
The rotary mower is used in combination with a tractor to mow crops over large areas. The unit is effective when working on high-yield fields and the surface heavily overgrown with small bushes and grass. The angle of the machine can be changed, so it can be used on inclined areas. The haymower can be installed on tractor MTZ-82 and other models.
- The tool is equipped with circular blades of discs, allowing to mow the plants evenly and lay them on the ground surface gently.
- The machine can be operated by 1 person.
- The cutting element is protected, what reduces the possibility of its damage.
- Blades can adjust to changes in terrain.
- Lower output than segment mowers.
- At low speeds the quality of work is reduced.
- It can only be used with tractors.
The cutting system is based on 4 rotors. The drive consists of a toothed and V-belt drive. It is powered by the tractor’s PTO. In addition to the mower, there is a gritter.
The principle of operation is that the tool rotates as the tractor engine revolves. The mower uses the tractor’s power to drive the machine. Several ways of transmitting power are used during operation: bevel, cardan, V-belt, toothed.
Rotary cutter is a device, to the upper part of which the rotors are attached, equipped with moving blades for cutting the plants. Rotary machines use about 60% of the tractor’s power, while other types of mowers use only 30%.
How they work?
There are two main types of non-industrial lawnmowers: cylindrical (drum) and rotary. Both can leave stripes in the grass if they have a large rear roller.
This is the best choice if you want an elite parterre lawn. Cylindrical mowers cut the grass like a pair of scissors. Several rotating blades are spirally mounted on a horizontal shaft; in addition, there is a fixed blade at the bottom; as the cylinder rotates, the grass gets into the slot between the rotating and fixed part and is cut.
The number of rotating blades varies from three to twelve, depending on the quality of the mower. The more blades, the smoother your lawn will be.
Most cylinder lawnmowers have two rollers: a small roller at the front and a big one at the back. The rear roller often rotates the cylinder with knives. The front roller in front of the cylinder supports the mower housing and enables the height of the cut to be adjusted.
Most cylindrical lawnmowers have a collector to collect the cut grass. It is usually located at the front: the blades attached to the cylinder, rotating, throw the clippings into it.
Rotary lawnmowers work on the principle of a grass cutter. Several blades rotate at high speed in a horizontal plane and cut the grass. The number of blades depends on the manufacturer, but usually there are two or four. They are made of hardened steel and must always be very sharp, otherwise the grass will not be cut, but pulled out of the lawn.
After mowing, the lawn will not be as smooth as with a cylindrical mower with many blades, but it can be compared to the results of a cylindrical mower with four or six blades.
Rotary mowers are good for cutting grass in the garden among the trees or for grass borders at flowerbeds, where an even pile is less important. They are also indispensable for mowing overgrown grass and uneven lawns.
Small rotary lawnmowers do not have a scraper on the back of the mower, but larger ones have a special drawer on the back.
Air cushion lawn mowers are a popular variety of rotary lawn mowers. They also work on the principle of a grass cutter, but do not need wheels. During operation, a powerful fan creates an air cushion and the mower moves on it without touching the ground. This makes it very manoeuvrable and allows you to mow grass on banks, slopes, uneven areas as well as tall or wet grass.
How to choose a lawn mower
A rational choice of lawn mower involves linking its technical and functional characteristics with the features of the area to be mowed, and user preferences. For this purpose it is recommended to make a table in which one column will contain the criteria established by you (personal preferences and site conditions), in the second. the correspondence of mower characteristics to these parameters, for example, “1. yes” and “0. no”, in the third. their weight characterizing the individual importance for you. The most significant factors will have the maximum weight. the multiplication factor of the points.
You can use our test, which will greatly simplify the choice of the type of mower (Table 2). To calculate the result, add up the points corresponding to your answers and compare the obtained value to the nominal values (given at the end of the table).
