Mcastles, you're way ahead of me on WC68 work time

I've had mine for about 3 weeks. It certainly works flawlessly - and a LOT faster than I can feed it. Yesterday I chipped one cubic yard of chips in less than an hour. I know it was 1 cuyd because I used the cardboard box that covered the
chipper when shipped.
I put the box on a little m/c trailer, filled the box and and spread the chips in the garden. That system was a pretty good one-time event though. I had to tear up the box to get the chips out. I suppose a small dump trailer would be ideal, but I didn't see one sitting around in my tool area. Minor problem - I'll deal with that.
Most of my chipping was 2" - 4" trees, but still had a good many 6" size. I haven't changed the pressure springs on the feed roller, so feeding the 6" size was difficult until I learned that feeding a smaller size tree first and adding the larger ones closely following it proved to be an easy feed system. I'm guessing that cutting the tree butt at an angle would eliminate that problem.
Never had anything like a jam or hesitation. I've slowed down the feed speed some to let the
chipper produce very small chips. Even at that, the WC68 works me more than enough. So far, I'm elated over the quality of the WC68. Right price, easy to set up and use, and works faster than me
