tech update - Mulchers and Attachments


The Tigercat 760B is a 550 hp class mulcher carrier that shares major components with the field-proven and similarly-classed Tigercat 480B track driven mulcher as well as the popular M726G wheel driven mulcher.

The 760B was designed primarily for silviculture applications. Forestry companies require the capability to efficiently clean up residual post-harvest forest debris and grind stumps to ground level. The 760B meets this requirement and the machine will also find application in large scale land clearing and right-of-way projects.

Tigercat also designed a 118” wide mulching head to complement the newest carrier. The 4061-30 mulching head is based on the original Tigercat 98” 4061, with several updates and enhancements. The 4061 has been rebranded as the 4061-25 and includes the same enhancements as the larger head.

Tigercat says that its mulcher carriers offer superior build quality, greater hydraulic efficiency, better operator ergonomics and easier access to components and daily service points than competing mulcher carriers. The result is greater uptime and higher productivity.


Quadco competes in two mulcher classes: a 44” cutting swath model and a 56” model. Both are boom-mounted, drum-type attachments powered by an oversize Rexroth variable displacement piston motor, common to high speed saw heads and a heavy belt drive system.

As with all Quadco attachments designed over the last 32 years, these two mulchers excel in severe duty applications from cutting heavy underbrush to chipping full size trees to pieces, and are especially well matched to boom feller bunchers and midsized-to-large excavators.

Quadco says its wide selection of mulcher cutting tools is unmatched in the industry. The four-sided and eight-sided, rotatable, heat treated steel teeth are the preferred choice among many loggers/contractors who are looking for high cutting efficiency and affordable replacement cost. Other applications, where repetitive ground contact is common, may require Quadco hammer-style teeth with carbide bits. It is the customer’s choice.

Diamond MowersDiamond Mowers

Diamond Mowers says it is a leading manufacturer of industrial mower, mulching, and brush cutting equipment for the skid steer market, offering a range of attachments for standard or high-flow skid steers and compact track loaders.

Mulching options include the Forestry Disc Mulcher, which has the ability to cut through trees up to a 14” diameter and mulch trees up to a 6” diameter. For a finer mulch, Diamond’s Drum Mulcher effectively clears material up to a 9” diameter.

For stump removal, Diamond Mowers offers two types of wheel-based grinders. Reflex is an easy-to-operate, cost-effective attachment with premium components. This model uses just one style of tooth for simple care and maintenance. The Miller model offers the same power and productivity of a self-propelled commercial unit at a fraction of the cost. Six-way wheel positioning with swing, lift, and telescoping functions allows operators to effectively remove stumps without repositioning the loader.


Loftness offers a full line of Battle Ax mulching attachments for skid steers, excavators and prime movers.

The Battle Ax features a unique rotor with built-in depth gauges which function similarly to raker teeth on chainsaws to prevent the attachment from engaging too much material at one time. This design is a better solution for managing the amount of material being fed into the attachment than competitive ring-style rotors which many operators find overly limiting, says the company.

Loftness adds that its Battle Ax models also feature a two-stage cutting chamber design which is capable of processing material more thoroughly than competitive units by cutting it twice. Depending on the model, the mulchers are offered with a choice of reversible planer knives, hard-surfaced planer knives or carbide teeth. The teeth are mounted to the rotor with a single bolt, allowing them to be easily reversed or replaced on the jobsite using a common hex socket.


Bandit offers a line of track forestry mulchers consisting of two models that can be equipped with a mulcher or stump grinder attachment. Each unit offers high productivity, ease of maintenance and optimal operator visibility and comfort, says the company.

The BTC-150 comes equipped with a Caterpillar 148 hp engine and a 72” wide mulcher head or the BTC-300 can be ordered with a John Deere 300 or Caterpillar 321 hp engine and 90” wide mulcher head. Two mulcher attachments for skid steers are also available.

Since 1983, Bandit has manufactured equipment for a multitude of wood waste processing markets. The vision since the beginning is to build quality, highly productive, easy-to-maintain equipment providing years of dependable service, the company says. The commitment to quality, innovation and dedication is instilled in every employee and is one of the main reasons why Bandit says it became an employee-owned company in 2018. These core values ensure each Bandit machine will leave the factory ready to exceed customer expectations.

SeppiSeppi M

The Seppi M Starsoil has been completely redesigned to better satisfy user needs. The transmission has been reinforced and can now be used on tractors up to 310 hp. Seppi M’s new technology, the 2-Speed Powershift transmission, is the first of its kind in the market. This transmission allows the operator to easily switch from one rotor speed to another without leaving the tractor cab and while the machine is still running, unlike the past when it was necessary to stop the tractor and machine, shift a mechanical lever on the central box, and then re-start. The advantages are clear: fast adaptation to field conditions and the right operating mode for all work situations.

In slow gear, approximately 500 rpm, the machine is suitable for all soil works and stone crushing. In fast gear, approximately 1500 rpm, it is suitable for surface mulching.

Seppi M has been a leader and innovator in providing combined tillers in the agricultural and forestry industries for many years, says the company. Combined tillers have long been highly appreciated in these sectors and Seppi continues to innovate making a customer favorite even more versatile.

IMH mulching heads from INDECO are described as the perfect tool for vegetation management, especially effective in the applications of right-of-way maintenance, power transmission line maintenance, railroad vegetation maintenance, ski areas/hunting clubs, fire breaks, and development clearing.

Made in the U.S. from high-quality steels, INDECO says its IMH mulching head attachments are the most robust and severe duty on the market. Models are available to fit excavators weighing between 5 and 45 tonnes as well as high-flow track loaders.


Fecon is home to the Bull Hog brush cutting and forestry mulching attachment. The Bull Hog is engineered with severe-duty body construction. Heavy steel and quality welding provide strength and longevity in all types of mulching conditions, says the company. Variable motor speeds maximize rotor speed and torque. It is available in a wide variety of configurations —excavator, skid steer, and hydraulic carrier, to name a few.

Customers can maximize uptime and productivity across different job site conditions with Fecon’s innovative and aggressive rotor systems, which are configured for their needs. The FGT (Fecon Grinding Technology) and DCR (Depth Control Rotor) rotors are available in all Bull Hog models and use the same proven bolt-on stub shafts and bearing systems for long-lasting durability. Fecon offers a variety of tool options to tailor both systems for maximum results in changing conditions.
