Tech Update - Brush cutters & mulchers

Advanced Forest EquipmentAdvanced Forest Equipment

Advanced Forest Equipment's (AFE) high performance mulching attachment for excavators delivers superior mulching capabilities without expensive, heavy power boosters. Developed and marketed by AFE, the attachment is available for excavators from 7-to-20-and-greater metric tons.

The secret is rotary disc mulching (RDM) technology. This proprietary technology boasts an innovative design that transfers maximum power to the attachment using only the existing hydraulics of the carrier, resulting in a mulcher that easily handles thick undergrowth and trees up to 20" in diameter.

No auxiliary power unit is required. The carrier is already built to handle the requirements of the attachment and the RDM attachment will spend its energy tearing up vegetation, not tearing up the base machine, says AFE.

Users of the attachment experience significant increases in productivity, without increasing costs, according to the company. Because no power boosters are needed, the machines can be lighter, use less fuel, and are more economical to transport--without sacrificing performance. www.advancedforest.com

BRONBRON

With 35 years in business behind it, the BRON mulcher is one of the industry's mulching pioneers. Today, BRON offers a full range of mulching tractors, from 275 to 700 hp, designed for strength with a light footprint. They are used in forestry, firefighting and site prep.

BRON recently introduced their smallest model, the 275. Built on a D3 undercarriage, the 275's low ground pressure rating is 3.5 psi. A D4 undercarriage is also available. The 275 includes BRON's oscillating tracks, which improve stability while maintaining constant ground pressure. Also standard is the heavy-duty cooling package.

Safety is a top priority in mulcher design, with all models ROPS, FOPS and OPS certified. The cab is engineered to protect the operator from rollovers and falling material. It also offers a comfortable environment for the operator, reducing fatigue with climate controls. A tilted cab makes it easier for full access to components.

BRON mulchers are powered by Cat diesel engines. The engine and hydraulics are strategically positioned for balanced weight and are easily serviced through vented panels along the sides and rear of the mulcher.

D&MD&M

D&M manufactures Slash-Buster extreme service forestry mulchers. Utilizing low-rpm mulching disks for safer operation, their excavator-mounted attachments can shred 18" diameter trees with ease--and all without an auxiliary engine. Operators can also vary the chip size, for quick results or a fine park-like effect. And an available third boom doubles the area that can be treated from a stationary position.

For maximum productivity, the teeth are designed to be field sharpened with an angle grinder, and are economical with a total cost of less than one dollar per hour of operation. Slash-Buster extreme service attachments are capable of higher production rates than a comparable drum shredder, says the company, and are designed to withstand the daily abuse of mulching trees, with some units operating in excess of 10,000 hours. www.slashbuster.com

DavcoDavco

Choosing a brush cutter for compact equipment is an important business decision. For efficiency and money making productivity, it's important to make that selection based on what's being cut, the terrain, desired end results, and ultimately, the cost per acre cleared.

Davco's Barda brush cutters are hard to beat when clearing vegetation, says the company. This heavy-duty brush cutter is fast cutting, easily mounted and is low maintenance. It uses tremendous flywheel inertia generating torque and does not require a high rpm to give the unit its optimum cutting speed. This makes it competitive with larger horsepower machines because it stores the energy built up from its tremendous flywheel inertia. This design spreads out the weight for better flotation. Satisfied customers with a Davco with drum-style heads have said they chose to use the Davco because it's faster and more economical to run.

The equipment cuts brush, shrubs, and trees up to 6", and offers lower operating and maintenance costs.
