I've been thinking about a
chipper for some time now, considering the WC68, WC88, and
Woodmaxx wm-8h.
Similar to most of the comments, I don't plan on chipping oak bigger than 4" as that's firewood (my woodbox has 2"-8" in it as we speak but if I have a
chipper I'll probably chip more than I take to the burn pile now), but lots of my stuff isn't straight - mostly scrub oak that goes every which way but straight, so I'm leaning to the full 8" square chutes.
My main concern is PTO hp; my tractor's apparently got 29hp, which is below the suggested range for those chippers, but I'm not going to chip big stuff at speed... should be ok? Also the next tractor will be bigger haha!
