I have averaged well over 100 dollars an hour on my CTL and at least that on the Mini ex. I am averaging over 150.00 per hour with the Min ex and mulcher. Sure I lose quite a few jobs but I prefer higher profit margins and less work over lower profit margins and more work.
And regardless of what you pay for your machine you have too figure operating costs based on a replacement machines price with below average trade in. You can not dictate your operating expenses off of the hopes of getting as good of a deal on a replacement machine as you got on the one your in. Thats a gamble and not good buisness.
