CHipper for a YM 155D

   / CHipper for a YM 155D #11  
Knowing there are single stage and two stage PTO driven snow blowers out there, is there such a thing for these woodchippers. It would explain why some of these machines can much on larger diameter branches at lower Hp.

So are there 2-stage PTO woodchippers then?
I don't believe so (on the 2stage). Of course the ratio of the pulleys mean a lot.
The bigger the chipper the bigger and heavier the flywheel. Rotating mass I believe is the secret. Plus bigger and more knives.
That's where all the hp is needed.
All my own opinion...😉

I sold my 8Hp machine that had 2 cutters when I got it. Opened it up and the 3rd one was missing. Order another cutter and it indeed was a huge difference. So huge the machine was scary at first. Dropped in a 3 inch branch and it disappear in under a second. Totally vanished. The Techumseh engine was impressive.
