Those with Bobcat's, or any Kubota engine for that matter, do you notice these machines to be especially difficult to start in cold weather. We just dipped down real cold last nite (10 degrees) and without the block heater plugged in, the 335 mini wouldn't start. The T190 has also been very stubborn in the past, although it hasn't been started during this cold spell. With the ASV, glow the plugs for about 10 seconds, and started like it was summer. The fuel isn't cut yet, but we are running degel.
