How's that possible when splitting knotty rubbish with a Hycrack though? It just adds load until the wood gives - as far as my limited experience can see once it's pulling in there's little you can do to stop it unless you declutch and wind it out by hand?

with the 1000 speed pto you can keep the revs on the 900 on tick over, anything with a knot stalls it before breaking it :) but we always try stoping the mog before it stalls anyway, even on the 411, as it makes getting the piece of would off easier :P

we have a shear bolt on the spliter anyway, where the pto joins.

Do you break many shear pins?

I didn't realise that to get 540/1000 rpm you need to be running to engine nearly flat out. I suppose when working hard you would want it to be throwing all the power it has at the implement, but that's going to cost a fair bit to fuel when running something like a chipper? Unless you get a 540 geared chipper, run the PTO at 1000? That would work for a smaller chipper right?

It's just geared different in the pto box. My Chipper needs 1000rpm at the pto but the mog runs at 2000 engine speed. The mog will rev to 3600 flat out. If you throw the 540/1000 lever over to run 540 pto you still run at 2000 engine rpm.

Never broken one yet  :)

As casto says, you run the Mog a 2000 rpm, which is fine for chipping. When doing paddocks we tend to run between 1600 and 2000 depending on the thickness.

Sorry about that - back on topic...

What I mean is, if you get a chipper designed to run at 540, you could then put the mog in 1000 and run it at half the revs it would need if it was in 540 to match? So just for arguments sake, a chipper that needs 540rpm could be run with the mog in 1000 and running 1000 engine rpm? So you would still have 540ish, just with less power?

You'd struggle with running at 1000 rpm, as you wouldn't have the torque. You could do it with really light stuff. You'd be better running in 540 at 2000rpm, you'd use around the same fuel, as the low down torque required at 1000rpm in 1000 speed would use quite a lot of fuel.

That's true. Free revs with little load is a good way forward. Hey - all this chat may even apply soon...

Haha! Good as that is it? It's starting to sound even better than the chip box that doesn't tip!
