Did a decent yard cleanup in the apple orchard yesterday with the WC-88 which was the biggest project I've done with it so far. I cut everything above about 3" or so into smoker wood (love apple smoked bacon and sausage!), so mostly smaller stuff but the trees had been poorly treated for 8 or so years and there was a LOT of it (much heavier pruning than I'm usually happy with but at least they look mostly like trees and not giant shrubs now).
A few things to note (I think this all carries over to the
woodmaxx mostly):
The here limit was really how fast we could haul things to the
chipper, although we were mostly chipping not too large of branches I was also feeding in 4 or 5 or more at a time. Feeding in large bundles wasn't a problem for the most part. The orchard wood tends to be a bit gnarly so the 8" wide infeed is definitely nice even for smaller stuff, saves a ton of time not having to trim to make it fit. I think you'd get 90% of the benefit in that regard with an 8x6 with most wood. It's still a lot of work, but I also mulched most of the apple trees for basically "free" (amortized cost of
chipper, tractor, and runtime cost of diesel .. aside.. lol).
This size lugs my 55hp (44hp claimed PTO) 5520H TYM a bit when it's spinning up the flywheel - this is a 24" x 1" flywheel so assuming it's about the same as the
woodmaxx that's a 200lb flywheel.. which is about the same as the 8800. I believe the
woodmaxx steals a little less HP for the hydraulic pump so maybe you get a bit of that back there... but I think most of the HP is going to the flywheel. You'd definitely want to keep the RPM's up a bit to avoid stalling anyway. It's fine when it's running though, the heavy flywheel definitely helps carry it around.
