Sometimes when cutting fresh sappy wood resin coats the sides of the blade which causes friction as it goes through the cut. This in turn causes the blade to get hot and loose tension and wobble in the cut which causes more friction, more heat and so on. to prevent this use a sharp blade with proper set (if not TCT). run at the correct speed, if the blade has been overheated get it retensioned by a saw doctor, and last of all clean the resin from the blade regularly using a solvent like pe*rol. And don't force the saw through the cut

Does anyone have a KRPAN CS420 processor as apparently some have been sold in the UK?

Remember that if you double the log size you quadruple the cross section. So as chippers get bigger they need a big step up in horse power and torque.

IH475 has Perkins A4.212 engine as used in most MF165

8.8 is only normal strength bolts 10.9 is high tensile

Can I please correct the above. I meant to say 'Very dangerous cutting multiple small stems WITHOUT clamping in my humble opinion.'

Very dangerous cutting multiple small stems with clamping in my humble opinion.

In terms of petrol saw benchs, for a 700mm saw you want to have at least 10hp. Early Hakki Pile Eagles were a available with 5.5hp Honda, which was fine on 100mm logs but very slow on anything bigger. Larges fitted a few with Kohler engines, either 8.5hp or 10hp with 2:1 reduction on the engine to get the gearing right. I have used a Posch with the 13hp B&S engine and it is as fast as a pto. I currently have a BGU with Honda GX 270 (9hp). This is also on top of the job.

Watch out for pto spec on 5100 range some JD have only 540 pto speed and I think it advisable to buy a tractor with both 540 and 1000

Can't speak personally about the Iveco, but do some relief driving of i-shift Volvo FM and FH on milk tankers which is hard on transmissions, they have been very reliable and are an absolute doodle to drive. A lot less tiring for the driver than manual transmission.

The new TP175 is sub 750kg with 35hp engine

A few years ago I went to a demonstration of large well known Austria chippers. They had 2 identical machines working side by side. One had a conveyor (supposedly taking less hp) and the other was the conventional blower type, both loading bulk trucks. A light breeze was blowing and the chips from the conveyor machine were being blown over the side of the truck where as the blower model blasted them into the trailers with very little spillage. You also don't have the range of adjustment of discharge with a conveyor. Only my observations.

My Nilfisk 150.1 is back in for repair at the moment and relative to the amount of use it has had has been in for repair too many times. Nothing major but annoying small repairs. I intend to change it for a Kranzle. I had one a few years ago and regretted selling it.

Make sure it's the version with hydraulic saw drive and not one of the early belt machines.

I've been able source genuine Solo parts from a Germany dealer who advertises on fleabay.
