does anyone know the torque settings for the blades on this chipper?

I never torqued mine. They were done up viddy, then tapped with a hammer to make sure. No probs.

An engineer would ask for the bolt size and pitch - thus giving a set torque measurement. Most people would say "FT, its a gut feeling thing", try ringing Vermeer in Wellingborough on 01933 274400.

nice one guys....next question: where can i get mine retro fitted with a knee bar?another.. can i do it myself with a bit of welding?etc.. is it worth it or should i just sell and buy something newer...didn't think i'd be needing it hse standard but turns out i will.

You might be able to buy the kit from Vermeer, you could make one yourself but the engineering skill level required is high (to do it right), and you may be better of buying a new chipper. Depends on the math.

As Pete says, would be worth contacting Vermeer UK, but also take it to such as an agricultural engineer for a price. They usually have the know how for fitting such devices and can be a little cheaper than an industrial engineer.

 

To be honest what ever route you choose,(although you may find it expensive) i would definately get it done as last week I was speaking to a guy from the council, and he said the HSE have started a clamp down on tree surgeon equipment, so watch out fellas!

 

Failing that, swap the machine.

Retro fitting isn’t difficult or complicated. The materials are readily available and not too expensive. I can talk you through it if you like. PM me for details

Yeah it is fairly doable either way. The kit from vermeer uk is around the 1500 mark if i recall, but i have seen 2 chippers with 'home-made' set ups. Both emplyed a simple system of a hydraulic valve under the feed hopper (the 620 already has a box under there which could be swapped for a spool valve) and a latch in the bar, which necessitates 2 handed release, which is basically the requirement for HSE. With one hand you release the catch, and with the other you put the bar back to the 'in' position and carrry on working.
