I have a 07 model td95D and haven't yet been able to figure out the right way to use the glow plug on it. It looks like just a single one in the intake on this tractor. We've been getting a lot of snow lately and low teens for temps. It's a bear to get started on these cold mornings. I haven't ever had to boost it or sprayed starting fluid in it. I don't believe in that stuff anyway. My owners manual doesn't say a thing about the intake heater. Anyone know how to use it? It's got a pushbutton on the dash and I can't tell a difference in starting pushing the button vs not.
