I've turned (turning) enough wrenches, I'm ready to hop on the seat and get the job done, without working on any more stuff. I find myself buying new these days.
I personally will not be buying a Tier 4 emissions piece of equipment for my own private use. The head aches I have experienced from the failure issues caused by using this equipment commercially is why I feel this way.
Also congrats on being able to turn your own wrench.
