500 Series USA Made Greenteeth®

Greenteeth® is a USA made, innovative tooth and pocket system that gives you the ability to rotate the tooth itself, providing a fresh cutting edge in a matter of seconds. Each tooth can be rotated using only a standard wrench and without having to remove the pocket! Since each tooth can be rotated to a new edge three times, it’s like having three teeth in one.

500 series Greenteeth® fit most machines under 20hp. The LoPro® Pocket Design is a slim design that allows for a 3/4″ clearance between the side of the pocket and the stump. This clearance prevents the pocket from rubbing against the stump, which reduces pocket wear and improves overall performance. This design is made from 4140 tool steel and Grade 8 heat-treated for greater durability and the pockets are reversible, so they can be used on either side of the wheel requiring less inventory to be kept on hand. It was also designed for maximum contact between the pocket and wheel for greater holding strength.

The LoPro® Bolt used is a smooth shank to reduce wheel wear.  They consist of a larger surface are on the angles shoulder for greater holding power and have a  tapered head to increase contact between the bolt and pocket. They’re also Grade 8 Heat treated for superior wear resistance.

12" Diameter Cutting Wheel

The large 12″ diameter, laminated cutting wheel secures the 8 tungsten teeth, providing superior strength to the cutting head to take on even the toughest of stumps.
