BENEFITS OF THE SEVENTM S-SERIES MULCHERS

  • Capable of producing Classe I / Category I Mulch to meet the most demanding mulching contract specifications. Class 1 / Category 1 MulchThe Seven S-Series mulchers feature a large diameter rotor with a close ratio hammer configuration, resulting in long hammer life, increased grinding capacity and the production of fine “Classe I/Category I mulch” (see chart). A fine mulch gives good ground cover and returns to nature quickly.
  • Excavator mounting allows the S-Series mulchers to reach into areas not accessible by wheeled or tracked mounted mulchers.
  • The Seven S-Series mulchers feature oversize roller bearings on the main shaft, a welded body of DOMEX® steel and skid pads made from HARDOX® steel giving the mulcher a long and productive life in the toughest of conditions. A hydraulically controlled gate ensures safe operation: gate is open for cutting and closed for mulching.
  • An ecological solution: mulching has proven environmental and economic advantages over the use of chemical sprays to control brush growth. Mulching eliminates the potential danger to the soil and water table.
  • Options: Third Member Integral Mounting Bracket Foot for E-Series mulchers.

ESB
Boltop

WIDEST

Patented side openings in rotary brush cutter skids for maximum utilization of working width of the machine. At the same time a better mulching of the material is ensured due to the blockage in the cavity created in the opening “window”.

ESB (External Shaft Bearing)

Built-in system applied to the side extension shafts of the gearbox and drive lines. The bearing of of the transmission extension is positioned on the side of the frame ensuring a very close distance between the pulley and this bearing, reducing dramatically the bending in the shaft. This will increases the life of the shaft, reduce the bearing loads and consequently also decrease the temperature in the drive line.

BOLTOP

System for assemblying the hammers to the rotor with special socket connection between bolts and lugs. The bolt head is completely embedded into the lug and ensures a precise fit, preventing rotation and loosening. The bolts are 10.9 quality and 27 mm with lock nut. This is the most robust assembly system in the market for swinging hammers, ensuring no bolts breakage and avoiding downtimes during work.

Sidestep
Flow up

SIDESTEP[

System for overcoming obstacles on the sides of forestry and agricultural mulchers. The pulleys surround plates are rigid and the reinforcement fairings make a wedge effect ensuring the lateral rigidity while avoiding obstacles snagging during work. This system reinvented traditional caps that did not act like a real protection, only made the barrier function between pulleys and the environment, but the impacts in some cases bended the cover causing serious problems to the drive line. With the Sidestep, the impacts to the sideways of the machines translate into simple happenings of daily work without any inconvenience to the integrity of the drive line.

FLOW UP

Flow Up is a cutting system consisting in  blades with flaps that cause a suction of  the material (grass, low brush…) in the  back part of the cutting area, ensuring a  better and cleaner cut. These blades are  assembled to concave plate with bolts and  bushes. The special shape of the rotor  ensures optimum sliding as close to the  ground as possible without damaging the  topsoil. Assembled in the range of rotary  brush cutters intended for green spaces,  large areas and farming works.

ALE

FTS

ALE (High Strenght Steel)

The steel has two main parts in their  behavior, the elastic and plastic. The elastic  part is a steel enabling a deformation  and subjecting this to recover its initial  properties. When we apply a force in the  steel and it crosses the line between  elastic and plastic, it will be deformed  permanently. Each steel has a load value  in the passing of the elastic to the plastic  zone. The high strength steels have a high  values in this load. The A.L.E. cold forming  steel has a yield stress value (point from  which appears the deformation), which  duplicates the value of a traditional steel.  TMC Cancela incorporates A.L.E. steel in the frame of its machines to provide an  extra quality, avoiding cracks and breaks in  the most demanding working conditions.

HDX (Wear Resistant Steel)

It’s a steel that has in its composition  many elements which give excellent  properties against abrasion and wear  without compromising important steel  factors such as bending and welding.  The wear-resistant values increase steel  double lifetime with respect to traditional  steel. Wear-resistant TMC Cancela  steels incorporate all the elements that  are in direct contact with the ground, such as skates, plates, inner shells and  counterblades.

FTS (Fan Transmission System)

System of refrigeration incorporated in the pulleys of the mulchers in order to  evacuate the heat of the pulleys and drive  transmission during the operation.
