Stump grinding teeth care?

[Jenny Tool]

To all stump grinder owners,

 

Being new to owning a stumpgrinder (Rayco RG13 series 2), im a bit lost on which way to maintain/sharpen/use the teeth. For example i bought a Saturn machine knives grinding disc especially for teeth sharpening, but at £55 odd + vat + postage i didnt know if this is cost effective, plus the disc doesnt seem to last long, or do you use the teeth until there blunt, bin them and replace with pattern parts or originals, or do you re tip them? Whats the most cost effective/time saving and performance gaining option? Also what blunts a stumpgrinding tooth very quickly?

 

Kind regards

I send my dull teeth out to be sharpened. Rocks are your #1 enemy of stump teeth #2 would be metal. I have tried to sharpen my own but found it to be more of a pain in the butt than it was worth. The guy I use charges me $2.75 a tooth for yellow jackets and I pay shipping. I would look around your area first you might find a good deal for sharpening.

i just replace as and when needed. some wear quicker than others so i just replace the ones that need doing. i bought one of those sharpening discs long time ago. complete waste of money and time trying to sharpen them.

Thanks nick, that was the impresion i was getting a complete waste of time and money, refering to flashcuts response(thank u) does anyone in the UK get there stumpgrinding teeth sharpened professionally?

I never had a problem sharpening them when I used to do grinding years ago, green wheel in a powerfull bench grinder and a bowl of water beside me, don't let them get so worn that they will take ages to do though otherwise it's just as well to sling them, oh and don't forget the mask.

I am going to try a diamond disk in the hand grinder and just touch them up on site this time though and see how that goes.

Weve used diamond disks with a hand grinder on our teeth for a while and it worked well:thumbup1:

I have a Vermeer that i had converted to the multi tip wheel and teeth and i have the teeth sharpened by the company that do our chipper blades. It costs me £2.50 a tooth and these teeth have 4 separate cutting edges. I used to do them myself with a green stone but it was a real PITA.

Really, i sharpen mine all the time on a green wheel, never had a problem. great waste just to throw them away when there dull.

If your going to sharpen them yourself I would invest in a diamond grinding wheel that mounts onto a bench grinder. They last way way longer than a green wheel and are approx a trillion times less hazardous to use.

 

Never tried the ones that mount on angle grinder but from what I hear it's best to grind the steel with a normal grinding disk but use the diamond for the tungsten as the steel can clog the diamond wheel up making it a lot harder to use.

 

I find the cobble stone type of rock the worst as it can smash the tungsten to bits! Always carry a good road bar to dig any stone/bricks out etc.
