lawn tractor?

Hello all I am considering building a hybrid lawn tractor,a 14 hp engine powering a generator(electric clutch).The theory is to make enough power to power wing mowers and the regular deck.Would I want to make 110 power or 12 volt or what?
thanks
Guy

With a higher voltage, you would be able to have a smaller (and lighter) engine at the same power rating of a lower-voltage one.

Finding traction or implement drive motors in the 12v DC range will be hard, and for them to be useful they will be enormous.

I've been fond of the original Etek (now long out of production) and its many copycats, most of which are actually pretty good. Etek clones are useful at voltages from 24v up to 72, a nice broad range that you should be able to hit regardless of what generator setup you use.

One Etek clone to power your drivetrain and another to power your implements should get the job done handily. NOTE: a single Etek can generate well over 15hp, completely soaking up every bit of your gas engine's output. Obviously you will want to include some power limiting hardware.

the generator will be driving only deck motors the hydrostatic drive will still be used,I don't know if it's all practical I just wanna do it.
