Which ZTR mowers can you get with lights, or light kits? I know the Hustler super z cannot have lights because of a voltage issue . Does anyone know if the Kubota ZD series has light kits available? I see a lot of grasshopper mowers with factory lights. I wonder why this is not standard on most mowers. In the fall when I'm working a lot of overtime I find myself mowing, and doing leaf work after dark quite often.
