Greatest density of carbide hammers in the industry. Unique efficient, spiral cutting pattern.

Lubrication points protected and well marked.

Twin double chain curtain (4 rows).

Adjustable, 20mm HARDOX® steel skids.

gearbox-ttwf

Oscillating gearbox maintains the same angle of the PTO shaft in any position.

The Seven TT-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.

 

Self-aligning roller bearings in rotor for assuming/ absorbing possible misalignments during operation. Replaceable shafts in rotor, bolted with special safety system.

 

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.

With the two stage hammer the central carbide point penetrates wood easier, the wider second carbide blade increases mulching action.

Replaceable 45mm wide hammers made of hard alloys with carbide wear points and DuoBoltTM mounting (F03 Hammers on center rotor, F04 hammer on side). The Model TTFT features unique “Two stage carbide hammers”. These 55mm wide F05 and F06 hammers have two separate levels of carbide cutting surfaces and a reinforced forged steel anvil which attaches the hammer to the rotor. Research has found that when mulching with machines over 200 HP, the mulching properties change. This is why on “Seven” mulchers the hammers used on a 100 HP mulcher are not the same hammers used on the larger models.

The benefit of the two stage hammer is: increased mulching speed, with lower fuel consumption.

  • The SEVEMTM TTW 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”*. A fine mulch gives good ground cover and returns to nature quickly.
  • The SEVENTM TTW mulchers feature 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.
  • The machine incorporates replaceable carbide tipped hammers, with the DuoBoltTM locking system, made of special alloys and hard metal designed to provide excellent material penetration and long life.
  • Large diameter rotor thickness. Electronically balanced. Assembled with self aligning spherical roller bearings with conical inner rings.
  • High performance belts. Replaceable front and rear chain curtains.
  • Available with optional hydraulic guard frame incorporating retractable raker teeth.

What is Classe 1/Category 1 Mulch?

The SEVENTM line of mulchers are engineered to producing fine mulch (Classe 1/Category

1). This fine mulch decomposes and returns to the soil much more quickly resulting in maximum ecological benefits often eliminating the need to remove debris from the site.

 

Most mulchers on the market today are capable of reducing brush to slash (Classe 3/ Category 3) or large chips (Classe 2/Category 2). In time, these larger pieces of debris will decompose and return to the soil.
