MULCHER WITH MOVABLE HAMMERS OR FIXED TEETH FOR EXCAVATOR: HERE ARE THE DIFFERENCES

Flail mower with movable hammers or fixed tines? The mulcher is a widely used and appreciated work tool in agricultural as well as forestry contexts. The care of forest soil, uncultivated or neglected areas, the cleaning of riverbeds, streams and canals, and also of areas close to railway lines, requires the use of mulchers. These are also indispensable in case of floods, disasters, landslides, to clear roads or areas, in favor of the passage of vehicles, people and emergency vehicles.

As can be guessed, mobile hammer trenches for excavators are tools that make versatility their prerogative. However, there are several species of them, including those with movable hammers and those with fixed teeth.

Let’s anticipate that the main difference between flail mowers with movable hammers and fixed-tooth flail mowers lies in the type of use. To understand this is to better guide the choice of the best flail head.

Mobile hammer mulcher for excavator

Mobile mallet cutting is a popular genre, as these are the most widely used not only because they identify a simpler system, but also because they are indicated in most cases to handle more common and less complex jobs.

Their wear and tear depends on the type of material being processed and the cutting height set, depending on the work being done. To extend their service life, it is possible to opt for movable mallet cutters whose cutting area is coated with surface treatments capable of preserving the sharpness from premature wear over time.

Fixed tooth mulcher for excavator

The fixed-tooth flail cutter is used mainly in forestry. The fixed tine works differently from the moving mace, and given the nomenclature, it is also easy to see why. While the mace “moves,” the tine remains fixed and integral with the cylindrical rotor to which it is attached, which, as it rotates, also rotates the cutting teeth. The teeth have the job of “eating the wood,” splitting and shattering it. Excavator trenches with fixed teeth are recommended for heavy-duty work such as intensive reclamation, cleaning river beds and embankments, working in heavily cluttered forested areas where there are thick logs and branches. In fact, thicker logs are cut with this system. It goes without saying that given the field of application, the fixed tooth mulcher should be mounted on larger machines since it requires more power to operate.

Characteristic movable mallet trenches

Operation: the hammers are called “mobile” because they move independently on a rotor shaft. These “hammers” strike the material repeatedly, shredding and breaking it into small pieces.
Materials to be processed: movable sledgehammers adapt better to different textures and medium to small sizes, allowing both soft and somewhat harder materials to be shredded.
Use: the mobile mallet excavator mul cher system is most effective for shredding remains from pruning, grass, crop residues, and various kinds of plant waste . In addition, such a mulcher can also handle fibrous and wet materials.
End result: the use of hammers in a mobile mallet shredder produces a finer, more homogeneous shredded material that could suit composting or other uses.

Considerations on mobile mallet trenches

It is clearly understood how the movable mallet is “limited” in use by the type of material it is going to tackle. The mobile mallet mulcher is used up to certain cutting diameters on wood, then limitations take over. Despite this, however, it is among the most widely used cutting systems for carrying out general maintenance as well. In essence, the mobile club excavator mulcher is very reliable and can assist the worker in tasks that require greater precision. This type of mulcher is preferred by workers because of its versatility, especially if it is not possible, a priori, to know thoroughly the ground on which to operate.

Verification of the fixed tooth mulcher

Operation: fixed teeth are used that do not move individually, but in solid with the rotor.
Materials to be processed: a fixed-tooth mulcher is more suitable for processing more difficult materials provided the equipment is installed on a high-powered vehicle.
Use: Fixed tooth cutting is commonly chosen for shredding wood, branches and similar materials, especially when trying to obtain a larger finished product or for specific applications.
End result: the shredding appears coarser and less homogeneous when compared with material shredded by a mobile hammer shredder. This is not necessarily a negative aspect, but it always depends on what is desired to be achieved.

Considerations on fixed-tine trenches

Among the fixed tine excavator trench range QM, for example, there is the possibility of being able to configure the head with different rotors, choosing from different types of fixed tines. There are, in fact, fixed tines made of carbide to operate with large logs reaching down to the ground, other tines have a double tip, also made of carbide, to handle heavier operations, while, for mixed work where you have medium-sized branches, or many brambles and shrubs, a mulcher with fixed tines made of carbide cutters is preferred.

Conclusion

The choice between an excavator mulcher with movable hammers and a fixed-tooth mulcher depends mainly on the type of material to be processed and the desired result. If finer and more versatile shredding is desired, the mobile hammer mulcher often proves to be the best choice. If you work primarily with harder materials and prefer a different cut, the fixed-tooth mulcher may be more appropriate.
