I say.......please do.....leave it running!No. That practice is for wannabees.
The reason that becomes a practice is often because the new owner has noticed (or heard of) large operators who leave their large diesels running for protracted periods…. and because they’ve been told that more wear occurs during start-up and shut-down than occurs during long idling periods.
The REAL story is that many large diesel operators have compressed-air starter motors and a loss of compressed air (often due to poorly maintained systems) may prevent a reliable start later-on…. or the 18 wheeler who’s stopped at the truck-stop for a nap and wants his AC or heat running during the nap…. and/or (Rarely these days) it’s not THEIR own rig and they’re not paying the fuel bill … or the agricultural operator who has his diesel sitting outside in the field all night with the temps down below freezing and needs to keep the equipment warmed up.
If I’m getting off the tractor for a few mins….yes I leave it running. But if it’s for more than 5-10 mins….OR…if I’m out of sight of the equipment for more than a moment….. I shut it down. Not only for economic reasons…but for Safety Reasons. Think about that.
The average tractor owner will Never wear his machine out due to starting cycles.
Not normally when actively using the tractor but I have no problem with the idea. If I have to get off like to move something when mowing or cut up a downed tree it could be 5 or 10 minutes. Ten or 20 minutes at cold start warmup is not at all uncommon.Do you leave your Kubota diesel tractor running when it may be 20 minutes or so before you will use it again?

Just for discussion’s sake….. take an old main bearing…. dip it in oil…and place it on a coffee-saucer for a couple of months…..and see how oily it still is.There is a great discussion about this - truckers may do this, but most of us simply shut down unless you are doing something fairly quick - I will let mine run for about 5 minutes or so.....
