idleing tractor for awhile

Just because truckers let them idle doesn't make it right.

Nothing stops pumping.

On these it does. After you put the range selector (an ordinary gear transmission) in Neutral, then nothing is rotating the little hydraulic pump in the Powershift.

The little pump is to engage the Powershift internal clutches - similar to an automotive A/T.

This is unrelated to the tractor's hydraulic system except they share the transmission case as their reservoir.

I don't think you need fluid circulation in the Powershift when nothing is revolving.

thanks for the help. i just wanted to make sure i wasn't going to burn up anything.

Idling causes carbon build-up, not a good thing.

starting causes greater wear!

I dont think you will hurt a diesel by letting it idle


This is bad advice a big cause of diesel engine failure is long idle times. There has been research done on this, infact I'd be willing to bet most manuals will say DO NOT let idle for long periods. It's your choice and money, but with todays engines it is better to shut down.

I'm not so sure about that

carbon may build up, but as long as it is run at a higher RPM periodically to blow carbon/soot out, you should be fine. Diesels are made to run continuously...

I fish in boats with diesels and much of the time is spent idling or trolling at the very bottom of RPM range...12 hours/day with 2-3 hours at cruise in/out.

I work at a Mack/Volvo/Isuzu dealership and most of what we sell are vocational trucks that do a lot of idling.

Schoolsout; is that considered a high idle or low idle. A higher rpm probably would not hurt but a low idle will eventually kill an engine. Back in the 90's{while I was TT driver} there were studies done on this, they proved without a doubt that low idle caused engine failure. In everything that I have read it seems okay to have the engine run at a small rev but not good to leave it idle for long periods. I know if I'm going to let any of my diesels sit then I'll rev them up just a bit, keeps oil pressure up and fluids moving. Some of the diesels have a very low rpm idle, that is where the issue's could/can/will start.

As far as Yanmar tractors I say let common sense prevail. Short idle time ok, long idle time, kill the engine.

I guess I'm just going by what I've always heard, which may/may not be the way to go.
