I live in the country and I have lots of trees in my yard and some of them are dying. I’ve been looking at buying a smaller 14-20hp stump grinder vs. renting something much larger. I am very capable of working on my own equipment. Are the smaller ones just a gimmick? How do they work on a bigger stump? Most of the trees in my yard are under 2ft diameter. I could see myself maybe doing some part time stump grinding too if the smaller machine does a decent job.

I have an old Lincoln weldanpower 8000 with an onan engine. It will idle up by itself if I plug in like a grinder or something but it won’t idle up when I strike an arc, I have to manually hit the switch. Anyone have ideas on fixing it?
