chipper in-feed rollers

[rossj]

hi all , im after some advice i have a greenmech 7" chipper i was wondering if it is possible to sharpen the in-feed rollers. they dont seem to grip the branches as i feel they should i was thinking of changing the spring in case its lost some of its tension or maybe trying to sharpen the rollers with an anglegrinder although this may effect the temper of the metal. or are the in-feed rollers a wear part that do need changing from time to time and if so how much are the parts ? all advice is gratefully recieved , many thanks.

yes i think it is , they are also replacable if they are too badly dammaged ,i would recommend that if your thinking of sharpening them i would get them sharpened proffessionaly and change the feed roler tension spring as well

Pete B will be the man to ask, sure he will be along at some point, failing that ring greenmech direct and ask them, have found them v.v. helpful.

We take our rollers out from time to time . Always sharpen them with a Grinder . Although we run a Timberwolf .

Can you not adjust the tension on the springs??

 

Dependent on the wear on the rollers, its some times worth building up the edge with some wield and then sharpening that.

do you have one feed roler with bladed edges and one feed roler with spiked edges ??

I fitted a double acting cylinder on mine to force the top roller down and smash the laterals off, works a treat at least 100% more efficient

 

You can also lift the top roller for bigger bits and clear any jammed timber, I know these are fitted a lot to big chippers but why not smaller machines?
