TECHUPDATE - Mulchers and Vegetation Control


Gilbert GM series grader-mowers are brush cutter heads that attach to the side of a motor grader for roadside maintenance. This head is said to be well-suited to forestry and municipal roads.

This patented concept cuts vegetation as opposed to mulching it. Gilbert says it is a more productive approach, with speeds four times faster than other applications and much lower operating costs. This allows the user to cover more mileage with the same or even less budget.

The GM-10 model has a cutting width of 8.5’ using five saw blades. It can cut stems up to an 8” diameter at an average travel speed of 6 km per hour. Since graders are often underutilized, the head can be installed on most graders using the standard hydraulic and fixing points for easy attaching and removal. The power needs of the GM-10 are provided by the grader without affecting its performance.


The PrimeTech tracked prime mover range was recently expanded to include the new PT-175, the most compact and lightweight vehicle of the PT range. It is designed for operators already familiar with compact vehicles, such as skid-steer loaders, but who require a more powerful and productive alternative for expanding their work options.

The PT-175 is designed to perform light to medium duty work in the forestry sector. One of its strong points is its dimensions, which enable it to work on sites with width restrictions. The PT-175 is mainly used for vegetation management, cleaning undergrowth, cutting and eliminating bushes and shrubs, and for cutting seismic lines.

The PT-175 features the same technology and components as other models in its range, though it encompasses a series of improved features and solutions that turn it into an even more advanced vehicle.

The PrimeTech brand was created in 2005 within Italy’s FAE Group, from which it inherits 20 years of experience in the design and construction of professional mulchers applicable to tractors, skid-steer loaders, excavators and special built carriers.


The Tigercat 480 is a 500 hp-class mulcher suitable for tough terrain, sensitive site applications and pipeline, exploration and other right-of-way projects.

High production and extremely low ground pressure combine to offer exceptional performance in the most demanding mulching jobs, says Tigercat. With a Cummins QSX15 Tier III engine, the 480 is a powerful machine with 440 hp available to the mulching attachment. The machine is compact and maneuverable with a narrow overall width and a light footprint for soft soil conditions.

A highly refined closed loop track drive system propels the carrier, and a dedicated pump powers the attachment. The 480 uses heavy duty track frames and a robust mounting system for the oscillating tracks. The efficient, high capacity cooling system uses a variable pitch fan with an automatic reversing cycle.

The machine incorporates high-lift boom geometry for improved performance on uneven terrain. The Counter-Rotate Function or CRF allows the 480 to pivot about its centre axis at the touch of a button for quick, effortless “on a dime” turns at the end of a row. All functions, including the joystick steering, are electronically controlled allowing for operator customization.

Tigercat has strived for the best possible access to daily service points and major components with large swing-out engine compartment doors and a tilting cab.
