[Market-farming] Wood Chipper

Mark,
Take a look at Vermeer chippers.
They used to make pto driven chippers, but I think they now only make 
self-powered units.
They have a model 1000 which can handle up to 12'' diameter logs which 
is driven by an 85 hp Perkins diesel.
I have owned and  used their 6" diameter series chippers in both pto and 
self-driven models. The advantage of the self-powered models is that 
they have a "smart feed" controller which adjusts the feed rate to 
engine speed, which means that you can start to feed a tree trunk into 
the unit and it will stop and start the feed, so you can go and get the 
next piece to feed in and not worry about the chipper bogging down. This 
saves a significant amount of time as the operator does not need to 
stand by the machine until the unit has finished chipping each piece. 
Production rate is high and the chippers are well made, easy to service, 
and can be left as "stand alone units", meaning that you can use your 
tractor to go and retrieve more material to chip. Really good operator 
safety features as well.
The other "productivity" tip for any unit is to keep your feedstock 
clean (don't drag that tree through mud and gravel before you put it 
through the chipper as this can dull the knives and knife block quickly) 
and keep your knives sharp and change them out often. Most chippers will 
work OK with semi sharp/dull knives (just like a dull chisel) , they 
will work extraordinarily well with really "sharp" knives (try using a 
really sharp chisel sometime, you won't need a mallet to make it cut), 
productivity increases exponentially and the chip quality improves 
(i.e.- not smashed bits of wood, but sliced chips).
No, I'm not a Vermeer salesman/dealer, I've just used their equipment 
for 10-15 years and really appreciate it.
