Zero turn tach

[Stryped]

I would like a lawn mower tach and hour meter mounted to the dash of my zero turn for tuning/ maintenance purposes as well as an oil pressure gauge.
Concerning the tack, the only thing I have found runs on batteries. I would like something that wires to the lawn mower batter so I do not have to keep changing batteries. Is there anything out there that will do that?

Probably not going to find anything, reasonably priced, that can be hardwired. Will probably have to look at either Tiny Tach or RunLeader. At the price of some of the TinyTach models, they may be the way to go. Only problem is their internal battery is non replaceable, but lasts 4-5 years.
