My Predator started chipping about like that this year (3rd year using at home). Took a little over an hour to get to the blades, sharpen them and reassemble. Was well worth it. Chips are around 3/4" square and nice and flat for the most part. I keep all of my White Oak chips and use them in my smoker. I also did a couple of Hickory trees, I use those chips as well. Then I make lump charcoal with both those hard woods. I also have 52 Cedar trees that I work as well. My wife takes those chips and makes closet sachets out of them. Sells them to a store here in Branson. Anything left that I have that is big enough, I make cutting boards and/or Cedar planks for grilling.
Depends on your needs watch the video and look the piles they each make. This is done for fuel for gasification. The blue drum chipper is the best for that application. But for garden Id go with the HF unit or the Orange unit. The orane unit makes nice fine chips for composting. If for landscaping with a drum chipper.
Matt I wonder if they would even chip running on wood gas. I was listening to the chippers you were testing and they bog down pretty good running on gasoline. What’s your thoughts?
If you are doing small engines under 1000cc forget this and go see my charcoal units. That is a better way. This is a dead end and waste of time and money at this scale. Wood Gasifiers are for Trucks / Charcoal Gasifiers are for power generators.
