I have 31hp at the pto. So, woodland Mills supports a 6 inch chipper. Woodmax 6, 8, or 9. 95 pct of chipping is fresh cut cedar. I like the woodmax 8800 but for some reason it has 2 blades. Bothe the woodmax 6 inch and 9 inch have 4 blades. Any thoughts on these 2 brands. Any experience or thoughts on 2 blades vs. 4?
