  • 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!
