When there is a problem of clearing abandoned areas of vegetation, shredding crop residues on the field or tree pruning in the garden of the choice of equipment is very clear, as there is no other machines providing the same level of performance, flexibility and security as mowers and shredders drivePTO tractor.The characteristics of these machines make them ideal and cost effective solution for farmers who need to cut and grind the tall grass, vines, shrubs and tree branches, and perform other similar tasks in the household.
If the decision is made to acquire flail, you must do the following, perhaps more important choice in favor of a particular model.Starting from different types of knives and ending with the type of drive manufacturers produce many varieties and models, seeking to meet the individual needs of users.To help understand all the options and choose the right model, while not overpaying money to spare, the following will be given some advice on the subject.
outset.
Before you proceed to the selection of flail, you must determine what it will be used.These machines can be connected on the back or the front of the tractor, as well as some models have the ability to dual-use items.For example, setting the shredders on the front of the tractor, can be mounted on the rear hitch and chisel to perform two operations for one passage: Shredders with loosening and incorporation into the soil.Therefore, you must first answer the question of whether the need shredder with universal application or can be limited to the machine to the front or rear of the tractor, in addition it will help to identify a suitable model of the tractor.
Selection of the knife.
After determining the type of work to flail time to think about the choice of the working bodies.It is best to choose between mobile and fixed teeth with hammers.Two types of knives are mounted on the rotors of different types and can not be used interchangeably, so it is very important to choose the most appropriate type.
movable hammers which are articulated to the rotor by means of rods use centrifugal force for powerful cutting stroke.Unfortunately, some people have a bad opinion about this kind of knives because of the negative experience in the past.However, many of these problems have been successfully solved in the modern models of cars.Another problem was the hammers moving machinery maintenance and repair.In the early models of mulchers each row of hammers positioned on a common shaft, so replacing one hammer is necessary to replace the entire series.Also, great difficulties have been the replacement of the rotor due to corrosion, damage or wear.Regardless hammers located in modern models allow to remove the old and put a new one in a few minutes, even in the field.
main advantage of mobile hammers is their design that allows for a meeting with a stone or a thick tree trunk to escape the hammer back, and do not stay still and to stop the rotor.This feature makes the machine suitable for use by inexperienced operators.Also with this type of machine knives are ideal for tractors of less than 100 hpfor grinding of material with a diameter of less than 15 cm.
Another type of knife is fixed tines, which are fixedly mounted on the rotor at the optimum cutting angle.This type of rotor is recommended for use with high power tractors for shredding branches with a diameter greater than 15 cm. There are several types of teeth with a similar design and are made of carbide materials.The advantages of such knives - strength and economic benefits in use, based on long life.They are designed to contact with rocks and require sharpening.However, the lower side of the blade has a rounded top which does not allow to work as quickly as the blades with sharp edges.
One variety of fixed teeth are made of hardened steel plates that have sharp edges, allowing the crushed material more effectively than other types of knives.Furthermore, machines with such blades requires less energy to complete the grinding.
other options.
After selecting blades should be considered components of the grinding chamber.Most manufacturers set the counter-knives that are welded inside the body for better grinding, but there are additional options in the form of the cutting beam.This increases the grinding efficiency, reduce the size of the crushed particles and prevents clogging of the camera crop residues and roots.
Other types of options are pushing frame and rear panel adjustable.Pushing frame is available with mechanical or hydraulic drive and serves to tilt standing trees during grinding.The rear panel may also have a mechanical or hydraulic adjustment, is required to select the distance by which the shredded material is scattered.
final option, which can be equipped with mowers, are associated with the drive system.It may be a system for automatically adjusting the belt tension or double drive for tractors over 125 hp
Increased in recent years interest in the mower is due to their unique versatility, performance, reliability, security and ease of use.With proper selection of the options can be successfully mow and shred almost any material.Tips given above will help sort out the large selection of models on the market and clear all obstacles in your way.
