Grinding for replanting

[lbj]

I have to grind several white pine stumps for new tree planting , I own a Vermeer 222/252 have grounded stumps deep before but never measured then , but the nusrsery wants them 16-24 below grade , looked up specs and 13 inches deep and looked at larger grinders which is still only 15 inches deep , what do you think ?

Thanks for any help

Pines have shallow roots as a rule of thumb. Grind it down to a full 13" and call it good. They will never be able to tell the difference.
In fact, 10" or 12" will get all the stump and roots anyway.

Do it by starting back a bit and ramp the grind downward. Like a skid loader digging a big hole.

I don't know about white pines, the pines we have in Texas go half way to China. If they want 16-24" below natural grade, that is a job for a track hoe, not a grinder.
