just spent 8 hours using a Woodmaxx WM-8H and fixing to spend another 8-10 hours on it today. all I can say is WOW, Iv'e used smaller trailer mounted chippers before from companys like Vermeer and Bandit... this thing will run shoulder to shoulder with them!!! My only gripe is I wish the infeed table was a bit lower. Highly recommend to anyone with tree covered acreage, makes quick easy cleanup, nice fine chips that break down fast.
