Gauges For a Lawn Tractor

I was looking on Royal Distributing for Temperature Gauges for my Snowmobile and There is one that has two different tips that might work a lawn tractor. One is a Spark Plug adapter(Measures Engine Temperatures) and one for an Exhaust Pipe that measures the Exhaust Gas Temperatures(you would need to weld in a nut and drill a hole in the exhaust). I thought it would be cool to have something like that on your engine. What else could you put on your tractor that would be cool?
Like RPM gauges, Fuel-to-air gauges, water temperature gauges(if its liquid cooled), hour meters, etc.?

I'd like to have a tach. Don't think I need anything else.

Yeah, I actually just ordered the tach I posted. my engine has no governor so i'm gonna watch it closely.

it would be cool to have a complate instrument panel. speed, tach,oil pressure, air/gas mixture, exaust temp, engine temp, and a million other kinds of gaufes

put it all around the steering wheel where light switches, throttle cables, etc. normally are, that would look cool. That was one of the things i wanted to do with the Toro(Analog tach, EGT, and hour meter), have the gauges on one side and the switches on the other. i totally forgot about this post:P

I would love an accurate speedometer and maybe an hour meter. And odometer, and temp gauges for both the engine oil and transaxle oil would be awesome too.

I have a tach on my mower and its nice to see what's it at. Maybe a oil temp gauge would be cool or oil pressure. If u had a pressurize motor. Lol

Tach would be nice, don't think I want to know what the temperature is. My friend added an oil temp to his Harley, and he has been paranoid ever since he looked at it on a hot day during a long run. Better off not knowing some things.

temp guage, rpm guage and speedometer would be sick, if a racer, put the tac that has the glow light that turns on when u need to shift
