"The Gyro-Trac Way"

Before Gyro-Trac, Biomass was not a cost effective source of renewable energy. But now with Gyro-Trac’s innovative technology the first cost effective and profitable way to harvest and deliver biomass as a renewable energy source is here!

Who is Gyro-Trac?

Technology (It Cuts Like An Ax)

Cuts like an Ax

Instead of hammering away at a tree like swing-tooth Cutter-heads, Gyro-Trac’s patented Cutter-head with planar style teeth, set in a spiral design and controlled bite ribs, can literally cut through trees like an ax. This planar style tooth gives you increased production while leaving a finer more attractive mulch. Operators can mulch the largest and toughest trees with the increased power of this fixed tooth spiral design and at the end-of-the-day leave the job-site looking like a park!




Low Ground Pressure

The captive track system is composed of three (3) multi-ply nylon and polyester reinforced tracks, assembled with heat treated steel cross-links. These tracks are enclosed by the machine’s steel tub on their inner side and a captive cage on the outer side, making throwing a track nearly impossible. Tracks mold to the terrain as the machine moves, distributing overall ground contact and giving the machine, it's incredibly “Low Ground Pressure” and enabling the machine to traverse swampy wetlands and steep rocky inclines with ease. The fact is, a Gyro-Trac machine can venture into some areas where humans on foot and other machines cannot.

Gyro-Trac’s aggressive floating track system traverses steeper and/or wetter terrain than steel tracked machines. Unlike steel tracks, which allow the Cutter-head to bounce, this terrain conforming system allows the Cutter-head to stay level on uneven terrain, maximizing productivity.

Optimized Hydraulic Formula

Gyro-Trac Mulchers utilize a Closed-loop Hydraulic System. Each track has its own heavy-duty traction motor and pumps. The Cutter-head’s drum is driven by one or two variable displacement hydraulic motors that are also driven by their own pumps. Each closed loop circuit maximizes hydraulic horsepower without sacrificing the drum’s cutting ability.

Gyro-Trac has Redesigned its Planar Style Fixed Tooth

Gyro-Trac is always looking for ways to improve their mulching machines and for 2015 we have redesigned and re-position the planar style teeth and holders on our Cutter-heads. We moved the planar style tooth holders from in-front-of the control bite ribs to between them and the result was a much finer mulch; almost like sawdust. This combination of planar style tooth design and tooth holder position on the rotor provides the most efficient cutting by smoothly chipping away at the brush.

The Canadian Biomass Market


The Canadian Biomass market is forecasted for huge growth potential based on the existence of its biomass feedstock resources and the push to grow the Biomass Industry.  With that in mind Gyro-Trac with its Bio-Energy Baling System has been working closely with the Canadian Department of Natural Resources and the Alberta Environment and Sustainable Resource Development, along with Private Contractors in providing a cost effective way of harvesting mulch for the Biomass Industry.



Follow Up News to Live Demo of the Bio-Energy Baling System


After a 3-week tour of Canada, Gyro-Trac is proud to say that the Bio-Energy Baling System (BBS) was huge success!

The BBS was shown at locations in Canada including Toronto, Winnipeg, Edmonton, Drayton Valley, and throughout Alberta. The response was overwhelmingly a success, as the attendees were impressed, shocked and stunned that a machine existed that was able to mulch, convey, chip to resize and bale in a 1-ton bale (AWESOME). With a 1-ton bale, a trucking company can now max out on weight, not volume.


Thank you to all who attended the Bio-Energy Baling Demo and a special thank you to all that helped put this demo together such as; Oliver’s Brush Hogging out of Beaufort, SC, Hedgeco Mulching of Drayton Valley, Alberta, Tim Keddy of the Department of Natural Resources of Canada, Tom Helgesen and the staff at Gyro-Trac.

New Cutter-head Safer, More Efficient…

District 7 has been using Boom/Slope mowers for a long time.  Recently, however, a newer type of Cutter-head from Gyro-Trac was installed that not only cuts brush and tree limbs, but grinds them into mulch without throwing the debris into the road.

Credit must be given to District 6 who was instrumental in getting these new Cutter-heads since they performed all of the original testing.  The result however is that SCDOT employees can now do their job in a safer, more efficient way. See more

These Cutter-heads have shown to be cost effective and safer since less debris flies away from the Cutter-head. The crew shown in the picture could not wait to brag on how good this machine worked.

With the acquisition of new Cutter-heads, we have been able to make a great deal of progress over the older Flail Head Cutters that were constantly breaking down and would not cut larger diameter material.  A similar type Cutter-head can also be used on the front of a Skid Steer Loader to cut brush where the Slope Mower Tractor cannot go.

Overall, the employees like the machine so they do their job better, and this means better results for the public.

Bio-Energy Baling System Used for Harvesting Mountain Beetle Infected Site


Innovative Harvest and Regeneration Design for Beetle Site Rehabilitation
By Tony Kryzanowski
Logging & Sawmilling Journal – February 2015

Results from test sites in Alberta show that implementing a rehabilitation design developed by the Canadian Wood Fibre Centre (CWFC) for mountain pine beetle infected stands with over 50 per cent mortality could deliver multiple benefits.

“We have been able to capture some value from these sites, tentatively reduce the pest and fire risk, and enhance stands to put them back on a productive trajectory to meet future objectives of the forest industry,” says Derek Sidders, CWFC Prairie Regional Co-ordinator and Program Manager.

With support from the Forest Resource Improvement Association of Alberta (FRIAA) Mountain Pine Beetle Rehabilitation Program, CWFC has partnered with Canfor, Spectrum Resources and University of Alberta researchers on an operational trial aimed at investigating the most effective way to recover value and rehabilitate beetle-affected small stem lodgepole pine mixed stands with over 50 per cent mortality. Forest companies avoid harvesting these sites because they have minimal conventional commercial value. However, left unchecked, they could have a significant impact on the future health and production of the commercial forest. Therefore, there is a need to develop an effective way to rehabilitate these sites. See how we are helping

This development project is taking place on forest blocks totaling approximately 450 hectares north of Grande Prairie. A CWFC-designed rehabilitation system, involving innovative harvesting and regeneration methods, is being deployed.

Sidders describes the harvest prescription as a full tree systematic harvesting pattern, using five metre wide parallel machine corridors centered at 20 metre intervals with landings servicing two to three machine corridors. Between each machine corridor is a 15 metre selection strip, which in total occupy about 75 per cent of the treatment area. Selection from within this area removes active attack trees, trees with commercial product potential and other stems impacting stand health and vigor.

He adds that green active-attacked, red-impacted, and green lodgepole pine trees greater than 20 centimetres in diameter or in dense patches are being recovered from the retention strips. White spruce and aspen are only being harvested from within the machine corridors and will be sorted for sawlog, OSB or biomass production.

If there are stands of dense, green, non-attacked lodgepole pine within the retention strips, the trees are spaced to about three metres between boles.

The completed area, consisting of multiple development and research test sites, will be harvested by the end of March, with site prep and planting taking place this spring and summer.

“We’ve found so far that the harvesting prescription is effective in meeting the objectives of the project and program and is reasonably easy to deploy operationally,” says Sidders.

Once operator training on the unique pattern was completed, the feller bunchers harvested down the machine corridor and back out to the landing, creating bunches from the machine corridor and selected wood from the retention strips. All bunches face the landing and are accessible from the machine corridor. Skidders backed down the machine corridors and grabbed bunches of green, red, and grey lodgepole pine, white spruce and aspen, sorting them into various decks at the landing. The material is then processed, based on the demand for the various products.

The biomass gathered from these sites is being mulched, chipped and compress-baled using a Gyro-Trac Biomass Baling System (BBS) unit, creating 700 to 1,000 kilogram bales for sale to the bio-energy or oil and gas sectors.   The BBS unit is owned and operated by Hedgeco Environmental Management LTD, of Drayton Valley (see pic above).

“Throughout all these operations, time and motion studies are being completed by the CWFC, as well as very detailed time and motions studies on the biomass baler by FPInnovations,” says Sidders.

The treated sites and landing areas are being site prepped for replanting using an excavator mounted mixing or mounding attachment to create suitable micro-sites. Sites will be replanted with white spruce and lodgepole pine. CWFC and University of Alberta researchers will monitor the research sites on an ongoing basis.
