I have built quite a maintenance biz since graduating high school. I don't take on the bigger install stuff for lack of experience with heavy equip...ie skidsteers etc. Sometimes I kick myself because I pass on some large install jobs. While my biz is prospering, i want to get into these larger jobs. How did you learn, did you go to school...OR just get out there and work...? Just curious about some of you experienced guys who run heavy equip??
