FOREST AND LAND CLEARING
Mulchers are the fastest and most effective way of clearing the forest floor. The process begins by removing big and valuable trees and large boulders. The mulcher is then driven over the forest floor a couple of times in different directions. Unlike when using an excavator to clear the forest, it is not necessary to remove soil and stumps from the area afterwards.
Our MJH and MJFS series mulchers are ideal for clearing large areas with many trees and dense vegetation, while our MJ and MJS models can be used for smaller areas. Our MJH mulcher has a subsoil working depth of 30 centimeters and a working width of 2.4–3.5 meters, and it is very effective at eliminating stumps. Since the working speed cannot exceed 5 km/h when clearing forests, productivity can be increased instead by increasing the working width. The maximum working width of the MJH model is as much 3.5 meters, but the total weight is still just four tons. The 3.5-meter mulcher can be powered by a large agricultural tractor or the SUOCCO crawler tractors by Suokone.
The MJH series mulcher is able to utilize all the power offered by large tractors. The MJH mulcher can operate with 400 horsepower, but the mulcher’s transmission can be specified to handle up to 800 horsepower.
Our heavy-duty MJFS series mulchers have a subsoil working depth of 40 centimeters without stressing the PTO drive shaft, which is articulated to enable truly deep subsoiling. In addition, MJFS mulchers have a pivoting rotor frame that makes it easy to mulch tall stumps and fell thick trees.
MJS, MJH and MJFS mulchers are available with an optional screen that produces extremely fine mulch. The crushing and screening takes place automatically while mulching, eliminating the need for a second fast-spinning mulcher. Instead, subsoiling and extremely fine mulch can be achieved with one machine.
Mulching logging residues and removing stumps after forest clearing is essential in many countries for pest control and for preparing the forest floor before new forest can be planted. Mulching is a much faster method than felling, clearing and transporting the stumps and branches away. Mulched branches and stumps are also excellent fertilizer for new trees.
Unlike mulchers by other manufacturers, MeriCrusher mulchers can reach depths of 20–40 centimeters beneath the surface. This can be achieved even with our agile 1.4–2.3 meter MJ series mulchers. Even stony soil with a high mineral content is not a problem, as our rotors spin relatively slowly with very high torque and are able to crush also stones. When the forest undergrowth is mixed with the mineral subsoil, it creates excellent soil for growing new forest.
Our MJ series mulchers can be powered by 50–150 horsepower tractors and our MJS series mulchers by 110-180 horsepower tractors. Small tractors are a benefit in the forest, as they are light, agile and inexpensive.
MeriCrusher mulchers use standard conical carbide cutters that cost a fraction of the price of custom made cutters.
FOREST ROAD MAINTENANCE
Mulchers are an excellent tool for maintaining forest roads. Mulchers can be used to repair bumpy and hard roads that can no longer be levelled with a blade.
MeriCrusher mulchers can reach depths of 20–40 centimeters beneath the surface of the road. All of the road materials, stones included, are crushed while the surface is levelled simultaneously.
The big advantage of using a mulcher is that it eliminates the need to transport road materials away and replace them with new materials. This generates significant savings in material and transportation costs, accelerates work and helps save the environment.
The RC models of our MJH series of mulchers have been designed especially for repairing gravel roads. Instead of a rear roller, they have hydraulic material feed guide plates in front and rear.
