The Official Work Pictures Thread

I've wondered about jam protection.

I didn't feed it max sized chunks our of concern for jamming.




Don’t worry about maxing it out, you can do it all day (as I did today as a matter of fact) stress control will deal with it.

It can happen if you turn it off before it’s emptied the chamber, because the wheel stops quickly (direct drive) a small piece can drop between the anvil and the blade.
It can happen once a year or never, but I once took the dog for a walk leaving the men to chip up a birch and they tried to start it for fifteen minutes, next day the flywheel bearings collapsed.
 
A Vermeer 1000 will jam often enough. I haven't found the exact pattern as to why. The worst was when, due to it's stupid design, someone simultaneously throttled it up and disengaged the clutch, and somehow the feed wheels were still working, ramming a branch into the freewheeling drum. That was a mess to clear.
 
I talked to another biz owner this morning. His BC900 is only 35 hp.

59 HP does a lot with hand feeding without autofeed engaging.
I'm only familiar with 25hp and 35hp rentals from a handful of occasions.
