Pros & cons greenmech blades

[Mick Dempsey]

On the modern ones I'm thinking, PeteB will have the definitive answer.

[Ty Korrigan]

In our Mk1. Quadchip, I tried round 2 blades. On conifer hedges the result was a horrible stringy shred rather than a nice square regular chip.

Could also be worn anvils though.

Square blades worked far better on our machine.

The two 190s we had and the current 200 all have 4 round blades and make lovely chip.

You have an arborist 200 or arbtrak?

[Ian C]

If they are better than the rest why are all manufacturers not using them.

It's called a patent!

Do you think the others would be using it?

The discs are ok but chip quality is poor IME. They do last well though..

[SAM66S]

Why do you prefer the flat ones?

 

 

Ty's response pretty much sums my experience up with them too.

I went from square to round on my quadchip and prefer the round ones they seem to last longer. I spoke to gm before I did it and they reckon the round put less stress on the flywheel bearings.

Our Quadchip has 997hours and is on it's 5th outer bearing change but now needs a new flywheel as the axle has been worn by braying the bearings off.

Inner bearing we changed once as a precaution but it could have gone on for another 500hours in reality.

Wish I'd sold it at 950hours...

Why so many bearings?
