I figured I'd write under this topic to get some imput from other veterans. I've been in business for 12 years now. I am still trying to figure out the best way to keep machine costs and repair costs to a minimum. I have 4 walkbehinds 3 standers and 1 rider. Do most of you guys continue to repair your equipment, trade them in, sell them, what? Repairs are expensive as well as down time. Purchasing new all the time is also very expensive. I am beginning to feel that after 2 years, when the warranties are up, the machines are becoming a big headache. I spend more time fixing stuff then I want to.
