Gyro-Trac’s SABRE-TOOTH TITAN cutting technology PULVERIZES Wood into Sawdust-like Mulch. The new SABRE-TOOTH design is the NEXT GENERATION of "disruptive technology," improving on Gyro-Trac's Planar tooth.

It begins with a WIDER TOOTH, held in place with a WEDGED FRICTION BLOCK, taking all the force off of the single bolt. THAT'S RIGHT! Only one bolt to quickly and easily replace worn teeth.

The CONTROLLED BITE is now achieved with TWO instead of one control rib under the tooth. The distance between control ribs is wider.

The KNOCK-OUT RELIEF that reduces resistance by allowing the wood chip to curl into the relief, now has a SPLIT BLOCK strategically placed to SPLIT THE CHIP and further REDUCE the size of the wood chip. This new design creates a SELF-CLEANING effect, clearing the tooth for the next bite.


I've used a variety of different cutter-heads and nothing comes close to the GYRO-TRAC!

Being in business over 30 years, I know a thing or two about Mulching. GYRO-TRAC's NEXUS system is th best in the business!
