All about rotary mower for tractor

Tractors, mini-tractors and motoblocks help to make life easier for all farmers: from small farms to powerful agricultural holdings. The main advantage of the tractor is the possibility of using trailed and attached equipment for different jobs. For example, for mowing or to prepare the field for sowing use different types of mowers.

Purpose of the mechanism

Mowers - These are mechanisms that have a wide range of tasks in agriculture and public utilities: harvesting fodder crops, harvesting, preparing the field for arable land, mowing park and house lawns, harvesting grass along roadsides. Due to high performance, simplicity and reliability of the design, the most widespread are rotary-type devices.

The mechanism of this unit is quite simple: several disks are mounted on a metal frame (cant), several knives are installed on disks on hinges (usually from 2 to 8), which turn and cut the grass as the disks rotate. Knives are made of hardened steel. Since the construction is quite simple, mowers of this type are easy to maintain and, if necessary, can be repaired independently.

Types of rotary mowers

There are several classifications mowers. Depending on the method of mowing, they are divided into:

• shearing the grass into a slope (left evenly over the area of ​​the field);
• mulching (grinding);
• folding the cut grass into rolls.

According to the method of aggregation to the tractor, there are two types of devices:

• mounted;
• trailed.

Perhaps a different position of the cutting system with respect to the tractor or the motoblock: front, side or rear. In addition, various gears can be used when connected to a power take-off shaft (PTO): belt, gear, cardan, conical.

Features of the design and principle of operation of mounted mowers

Attachments for tractors do not have their own undercarriage, it may have one or several support wheels, but only a small part of the weight is transferred to them.Therefore, these are usually mechanisms of relatively low weight and performance. Rotary mounted mower easily connects to the tractor with a PTO and is easy to operate and maintain. These units are used for processing areas of small size, although they can be used in the fields. Comfortable when working on uneven terrain. This is the most popular type of mowers with users of motor-blocks and mini-tractors.

How does the trailer mechanism

Trailed mower consists of a frame frame, based on pneumatic wheels. Cutting elements (discs with knives attached to them) are attached to the frame frame with sprinkles and traction mechanisms. Also on the frame are located the control levers of transmission mechanisms. The third point of support is the beam of the tractor.

Trailed units in comparison with mounted, as a rule, have a greater working grip, require more power and, consequently, more productive. They are used in the fields of a large area.

How to install the mower on the tractor

Before installing the machine on the tractor, check all the connections and tighten all the bolts.Then, in the case of installation of attachments, the connecting rods of the attachment of the tractor are connected to the connecting axes of the frame of the installed equipment. When installing a trailed mower, respectively, use a trailed mechanism. Then connect the drive (drive shaft, gear, belt or bevel gear, hydraulic drive) to the tractor PTO. In the presence of hydraulic devices that provide vertical and horizontal movement of the mower, they are connected to the outputs of the hydraulic system of the base unit.

Tips for choosing a model

When choosing a rotary mower for a tractor or motoblock, the following factors should be taken into account:

• types of vegetation: for harvesting plants with a hard thick stem a more powerful aggregate is needed;
• size and relief of the field to be processed: for fields of a large area with complex terrain, trailed models are preferable;
• mowing target: it is better to take a mulch model during primary field processing, and when laying fodder hay - stacking hay in rolls;
• price: Equipment of European, American or Japanese manufacturers of high quality, but expensive; Chinese products can be bought cheaply, but quality is not guaranteed; domestic products occupy an intermediate position and at the same time advantageous availability of spare parts.

For private and small farms, where they work mainly with walking tractors and mini-tractors, the Centaur-type LX2060 mower is a good choice. This device is connected using a splined drive to the PTO, has a width of 80 cm and a cutting height of 5 cm, which is well suited for lawns. For large farms need more productive equipment. For example, rotary mowers manufactured by Wirax, which are suitable for connection to MTZ, Xingtai, Jinma and others.

The best mowers for processing large fields are trailed variations, for example the Krone EasyCut 3210 CRi.They have a width of 3.14 m, they are equipped with 5 rotors, mowed grass is placed in rolls and have a capacity from 3.5 to 4.0 ha / h. Modern technology can significantly ease the life of a farmer, and, of course, the mechanization of labor should not be neglected. The main thing is to make the right choice, based on urgent needs and current financial opportunities.
