In 1980, the first forestry rotor was developed, a revolutionary innovation in the sector, so revolutionary that forestry became one of the Seppi M’s key areas of business.

Medium- and high-power forestry mulchers are a fundamental tool in forestry and environmental care. They are used to grind stumps and roots, clear the forest of fallen trees and decaying wood, as well as trees damaged by bad weather such as storms, or forest fires.

Forestry mulchers are now being increasingly employed to clear and fell trees affected by harmful parasites that are becoming more widespread, infesting woods and forests all over the world. A race against time, which calls for increasingly powerful tractors and machines, where medium-power mulchers are replaced by upgraded versions.

This means greater productivity, improved efficiency and reduced working times.


In this line of work, however, it is not just a question of first-class performance. The working conditions are very demanding and stones and earth are also found along with the huge piles of material.

This, combined with the climate conditions, are all factors that affect the life of the machine.

So, what solution can Seppi M offer? The answer comes directly from our customers, with whom ongoing collaboration is all-important. The search for the best solutions led the engineers of the Seppi M. R&D department to develop an upgrade of the Maxiforst high-power forestry mulcher.

This resulted in the second generation Maxiforst.

A completely new machine with a new design too, which combines the much-appreciated features of cutting quality, reliability and ease of use, showcased in the previous Maxiforst version, with the latest technology and solutions developed over the years, thus taking the new Maxiforst to a whole new level.

The new machine is designed to be used on PTO tractors with a power range from 300- to 500-hp, focusing on the key features of maximum wear resistance, optimal protection of the transmission of both the tractor and the machine, quality and high working speed, cutting-edge technology and operator safety.
Wear resistance is guaranteed by the high-quality steel construction, with the addition of Hardox plates in the grinding unit, which can be easily replaced at the end of their life, a feature already widely adopted in the stone crushing machines.

The sturdy steel skids now also have an interchangeable wear plate, so it will no longer be necessary to change the whole skid or lose time restoring it by welding with a filler.

The transmission has been completely revamped, the central box has the ADAM alignment system as standard supply, while the transmission of motion to the rotor is guaranteed by the tried and tested system with six V-belts on each side. The machine can also be fitted (optional) with the new starting system with M-Turbo fluid couplings, which replace the previous system with mechanical centrifugal clutches, and guarantee a smooth start of the rotor and greater protection from impacts on the tractor’s PTO, as well as greater reliability. New optimized ventilation is also included, which, combined with the integrated cooling system, protects the entire system from overheating, thus ensuring maximum lubrication and sealing performance of the components. The temperature can be kept controlled directly from the tractor, using ISOBUS technology, which is available as an option.

The speed and quality of the cut are guaranteed by the rotor featuring the patented V-Lock tool mounting system. The benefits of this system are: reduced rotor wear, better balance, easier and faster tool changeover, cutting capacity for trees up to 60 centimetres in diameter, and the mounting of heavy-duty wear-resistant tools with tungsten carbide insert and more slender tips, which in combination with the five rows of tempered counter knives on the frame, offer a finer and more uniform mulching performance.
