Idle time vs wear and tear on starter

[LouNY]

Once mine is started if I'm going to be off and on constantly the tractor stays running, usually 1200-1500 rpm just because it sounds and feels better at those rpm then idled down to minimum.
If I'm changing an implement that I need to depressure the hydraulics and I can't find a sweet spot by actuating them I will shut down to release the pressure then usually reach in and start it up again.
Or when I operating the tractor and need to take a phone call I may throttle way down, shut the pto off, and if I'm still having problems hearing then shut down the tractor.

Around 10 mins idle time if not hooking on attachment or outside temp cold,than give it little extra RPM's in case any build up in exhaust.

For implement changes I leave the tractor running because you値l be moving it and using the hydraulics. For other task there痴 a lot more consideration than starter wear. Being able to talk to your helper is a prime reason to cut it off.

Idling isn’t that big of a deal as long as the engine is truly only idling. Where people get into trouble with a DPF tractor is when they run the engine at low rpm while using the tractor.
Every time engine RPM is increased, it creates more soot. Every time a load is put on the engine, it adds fuel and makes more soot.
My tractor spent it’s first 25 hours mostly idling while I learned to mount and dismount all the attachments I bought and or refurbed before I took it all down to the ranch. It still performed its first regen at exactly 50 hours.
Don’t move the tractor while the engine is cold and at a slow idle, especially if you have an HST trans.
If the tractor is warmed up, there is no problem dropping it to a slow idle for 10 or 15 minutes while changing an implement.

You are supposed to idle for 2 minutes before shutting off anyway...if it is the same as my 4140.

I let it idle unless it will be shut off for 10 minutes or so. I need it running to adjust the 3PH anyway...only shut down for PTO attachments.

I idle the L47 and L3800 five minutes before shutdown . And let them warm up until the oil filter is warm. I don't let the L47 idle that much I do on the L3800 because it has no DPF filter.....

i dont mind idling mine as diesels can handle it. but i never hook up a pto implement with tractor running. never.

also my old tractor was 10 years old and on original starter. the newer kioti is now 10 years old and original starter. both had/have 1400 hours on them or more

For the most part, I leave my 4520 idling for up to 10 minutes or so....in cold weather, I'll let it idle longer. However, I don't idle at minimum RPM...normally at 1500 RPM.
I do shut it down if I have to connect a PTO driveshaft. I might be paranoid, but I want no chance of an accidental PTO engagement.

Same here, not below 1500 rpm unless idle prior to a shutdown.

You have a mix of people posting replies here. Those with and without DPF. There’s a difference.

I pull mine down to an idle when its not under load and for very short time frames. An example: When I first start it up, I let it idle, at idle, for a bit before bumping it up to about 1500rpm. Another example is when I enguage the PTO, I pull it all the way down, turn the switch, once the violent motions about settled, rev 'er up to PTO speeds. I also idle, all the way down, when I just need to jump off for a few seconds to grab something, maybe go to the bathroom, etc. And when I shut it down, I let it idle for a bit to cool the turbo before shutting it down.

When hooking and unhooking implements, its running at 1500rpm. I pull it down to idle before shutdown when I am attaching or detaching the PTO shafts. I do not let the engine run when I am playing with those shafts. Even though I am (mostly) alone, no one is in the cab, its just habit, and a good one to have.

The reason I assume people have questions like these is because of this DPF, they have heard horror stories. Do the regen when the tractor requires it. Dont drive the tractor or otherwise put the engine under a load at absolute idle. 1500rpm is kinda like my new idle. I keep the hand throttle there and use the foot throttle for more RPM unless I am doing something (like brush hogging) that would require the engine to be at operating RPM's (around 2k-max). Hope this helps.
