questions for stump grinding

[dtm165]

Hi, just began in operation of a stump removal business. I recently purchased a Rayco Super RG 50, and I have a few questions. What are pockets, and do I need them? For changing the teeth will a 345 Torque battery impact wrench be able to take them off? What does it mean to torque the bolts? Thanks very much, Daniel

Pockets are the pieces of metal on both side of the wheel that the bolts go through and hold the teeth. So yes, you need pockets. I think for green teeth the bolts should be torqued at 200 ft lbs. But after they've been in there for a while, i think your electric impact is gonna "no way hose' " to get them loose. I personally don't torque my bolts (using a torque wrench) i use my air impact wrench and tighten them up pretty tight. If you have a pic. of the cutting wheel, we can tell what type of cutting system you have.

Time to read your owners manual.

Torquing the bolts means to get them to a certain tightness, as measured in Foot-Pounds, or Newton-Meters. Generally in the U.S. it's Foot-Pounds. In the case of stump grinder teeth, it's important to get them tight enough, whether you actually torque them to spec or not, so you don't throw a tooth and either hurt someone/something, and additionally throw your cutter wheel out of balance. You might not think that a single tooth matters much, with the weight of the cutter wheel, but I threw a tooth off of a SC252 that the rental company didn't service correctly and it felt like the wheel was gonna shake the machine apart. After that I was down, no more grinding.
Some of those battery impact wrenches are pretty strong nowadays. I can't comment on whether yours has enough torque to do the job. You'll have to see for yourself. I will say that I put never-seize on my pocket bolts to make sure they will come out for the next servicing.

buy a torque wrench and learn how to use it. It's important to not over or under torque the bolts. A good torque wrench will last forever and its a good investment. Keep asking questions.... Mike

Danial,Surely you jest. Ok, Its the clump of metal on each side of that big round thing on the front of your machine.when those pointed things wear down after a while you will need to get some more pointed things. the pockets hold the pointed things on the big round thing. Hope i'm not being to technical.

DTM165,

G'day mate, hows the business going?

Hows the machine going, bet its all been a pretty big learning curve?

I started last year, gowing steadily as I focus and ID the best advertising.
