My Z482 in my bolens is becoming more dependent on 2 battery's When it is cold Under 15 Degrees Celcius in the morning and I am thinking of upgrading the starter to a Gear reduction version

Check to make sure both glow plugs are working. It'll start with one but it's a lot harder.

Learning more on the G4200 everyday...lol. I know about the dash indicator, however, I have a friend that has a diesel shop and he says to visually verify that the glow plugs are heating up inside the head, because the dash element may be weak or not working. I removed the injectors and I could see the plugs glowing bright as Christmas lights. I also manipulated the fuel plumbing as to hook the injectors outside of the head to see the spray patterns, and #1 looked different than #2. I now have them at said friend's shop so he can "pop" test them. Kubota says 1990-2150 psi. One thing at a time (or after another). After explaining symptoms, and everything I have done thus far, he says it sounds like an injector problem. So now waiting to hear back from him, and preparing myself to purchase a set of injectors.

If the glow plugs aren't working or barely working, then the indicator will not glow bright red, as too little or no current will be drawn.  The injectors can cause a lot of issues, so you're on the right path there.

I don't have anything new to add except that I have had 2 diesel compact tractors. One only required 30-40 seconds of glow plug warming to start in any thing below 50deg. My other one REQUIRED at least 60 seconds at 35ish to 50deg. Below freezing and it required a good 90 seconds of glow plug heating.

Gear reduction starter will make it spin over super fast and start it so easily. You have to get one off of a bigger motor like a d1105
