Hi folks...new to the forum. Did a search and didn't see my topic addressed. I have a 307SSR, and I'm trying to find a resource that tells me the size breaker I should use for my 17,000 lb machine. I was hoping for a chart that addresses all breaker manufacturers with their eqivolencies. I'm looking at various makes and models on Iron Planet, but cannot distinguish sizing without knowing what models numbers are for which weight class. Also need to know for a 312 class machine (26,000 lbs). Thanks for your help in advance!!!
