Features

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.

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

High performance drive belts or poly chain

Easy to replace, bolt on carbide tipped mulcher teeth with the DuoBoltTM locking system.

Replaceable counter blades

Welded mainframe with double layer of high strength cold forming DOMEX® S700 steel. Enclosed body system prevents debris from entering the internal components.  VOITH hydraulic couplings are optional for soft and progressive start and shutdown in overloads. Special cooling system made in Germany.

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.

The SEVENTM 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.

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.
