As John T states a voltage regulator is HIGHLY preferred over a cutout. Unless you use your tractor only for show, with a cutout you run a constant risk of overcharging (and ruining) the battery, or continually undercharging it. A voltage regulator eliminates this risk.

How to tell whether your tractor has a cutout or VR? The resistor on the bottom of the light switch would be the field resistor, meaning the tractor came originally equipped with a cutout. (Having A 4-position light switch also means cutout.)

But someone may have replaced the cutout with a VR at some point. And IHC cutouts and VR’s can look the same externally. Only sure way to tell is to remove the cover and peek inside. I you see only 1 relay it's a cutout; 2 relays is a VR. Also IHC cutouts have 3 terminals (BAT, GEN and F) while most VR’s have 4 terminals (BAT, GEN, FLD and L).

My recommendation is to get a voltage regulator with a curved mounting bracket to fit on the generator (TSC has 'em), wire it up and be done!!
