The issue (besides vibration from the spaced out teeth and pockets) will be the fact that less cutters will require maximum wheel rpm constantly and tooth wear will be accelerated. When and if you do need new green teeth, PM me and I'll pick them up for you as I pay no sales tax on them (farm use) unlike on line where you probably will and they are very handy for me and I like visiting their shop and business. Good folks there. I have an open ag exempt account with them (exemption cert on file) like all my suppliers. When you do require them I suggest going to the Wear Sharp 700 series if you don't already have them. They are more substantial, have larger carbides as well and are indexable to 3 positions like all Green Teeth are. I very seldom run mine at rated (540) rpm, usually much less but still in the maximum torque range of the engine on the tractor simply because the tractor makes 90 pto at 540 and my grinder is rated for much less and I don't need to be tearing it up, it is new and guaranteed. I don't want to explore the guarantee of I don't have to.
