I just bought my grinder....It has the Yellow Jacket system on it...How do I tell when they are dull??? I've never seen them in new condition so i dont know if they are worn out now or not....Looks like a fairly flat oval to me !!!! I have no clue....I just wanna eat some stumps !!!!
I have a 630B with a wheel off of a 630A (i think) and just put green teeth on it. Works great. My cutting times have decreased alot.
I'll have to measure it. When i went to order the green teeth set-up from baileys, none of the 630B kits would fit my wheel. Mine is 1/2" wide with 9 pockets, and the 630B's were 1" wide and i think 4 or 6 pockets.
I talked to him. He hasnt got the set up for the yellowjackets yet but he is working on it. Nice fella.
