Question About Vermeer SC352 Stump Grinder

[chipmaker29]

Hey Guys,

New to this forum and I hope I am asking this question in the right location. I apologize if not, please bear with me as I learn more about this forum.

We have a Vemeer SC352 Grinder and have only owned it for a couple months. During that time we have had some problems with it including electrical problems with the terminal block as well as problems with bolts breaking that hold the carbide teeth in place.

I was wondering if anyone else has had problems with these bolts breaking? Any advice for me in trying to decrease the frequency of this problem or how any of you have dealt with this issue? It is really a pain to have them break in the middle of a job then have to dig thru a chip pile to find the teeth as it throws them of course when the bolts break.

Also, any tips or tricks or preventive maintenance advice to avoid costly repairs would be really helpful. I have read a little on here about others experience with this model grinder and we always work on our own equipment to avoid costly trips to the dealer.

Any advice would be greatly appreciated. Thank you in advance and I really love this forum and enjoy reading about everyones experience with this trade.

I don't have the grinder you have but I do know about bolts breaking. One of the biggest problems is overtightening of the bolts. Seems logical to do but in reality its stressing the bolts and with the forces exerted on them while grinding, they will break, throwing bolts and teeth everywhere. Be greatful they haven't hit you yet. I know of a guy that rented one and the tooth broke. Hit him in the jaw. Never had to work again.

Another reason for the bolts breaking could be old bolts. Again, the forces exerted torque the bolts and eventually they will be no good, and eventually could break. Again, from my own experience with a chipper, old bolts broke. What a mess.

Best advise, tighten the bolts according to the manual with a tourque wrench, use new bolts and replace every so often, (dealer my know when) and keep the teeth sharp.

Thanks so much for your advice & opinion!! I appreciate your response. I will check the manual for the torque spec on the bolts.
