TESTIMONIALS

I want to sincerely thank you for your help when I was just getting set up because you were very helpful to me on the phone a few times when I needed advice. You helped me a lot,  and your AV-40 is an excellent machine well made and well designed.  Your videos also are top notch for a beginner to learn from. Best wishes to you in the years to come.

AV-56 Stump Bit Grinders

Sharpening stump bits can be an excellent  business of its own.

This machine will sharpen both the radius and face of stump grinding bits of all the popular stump grinding machines*. This machine comes with a special plated radius grinding wheel which saves a lot of time. All you have to do is put the radius of the bit into the radius on the wheel. The majority of the bits can be sharpened in less then one minute per bit. The motor also tilts for easy alignment of the angled stump bits. Comes complete with machine light, instructional video tape and instructions.

*Optional wheels and fixtures available for the Green tooth and Yellow Jacket bits.

You can add the AV-54 Automatic Knife grinding machine to sharpen the chipper knives.
