I'm sure a lot of this has been discussed and I could do a search but I'm wondering more about my particular machine. I have a John Deere CT332. On cold mornings, I typically run the glow plugs for around 20-30 seconds (until the light turns off), and then start the machine with about 1/3 throttle. I then let it sit for about 20-30 minutes or at least until the hydraulic fluid temperature is over about 65. Does this sound like a proper procedure or should I be doing things differently? The machine does have an electric plug in block heater which I have yet to use, does anyone have experience using the block heater? Thanks.
