Heizohack HM8-400

Increasing the RPMs you will increase the amount of fines in the chip. The rotor will chip more than the sieve can cope with.

I found the best speed to run a heizohack at is 700rpm this gives a very good quality chip , if you rev it too high with a powerfull tractor the chips cant get out of the sieve quick enough and this will cause a lot more fines

Using the 1000 pto you should have the tractor running around 1500 rpm which should be where your maximum torque is you will get good chip and use a lot less fuel
