Had an FMC Wayne I've used for years. Looks like h---, but chips like a beast. When I pull up people get this sort of look like, well, that's an old rustbucket till they see it run and the looks turn to respect and a little awe when it sucks 25' trees in and spits them out in seconds.
Mine's a 9-inch and I can chip 4" all day, 6" pretty easily. I've chipped a lot of 8", but need to cut it into maybe 2-3' chunks or it bogs down and kills the engine since there's no auto-feed. I recently tried reshaping the knife edges by putting a slight bevel on the last sixteenth of an inch or so and could feed long 8" logs as it would eat a foot or two, then stop and I could tap the log and it'd eat another couple feet. This stopped it from bogging down, but it's also not optimum for chipping as the knife angles aren't ideal.
I had the knives reground to the recommended 36 degrees today and will rotate the bed knife to a fresh edge, set the clearance and see how it behaves as I've only ever hand ground it myself.
Anyone have any experience putting big wood through these and is it the same or different from what I've described above?
