Leave it running?

[x595]

15 min. or less I leave it idle at around a 1/4 throttle , anything longer and I
shut it down after a cool down period ...

Hey WH401 , those Diesel fumes are fresh air ...

Later,x595

I don't plan to be the first one to get lung cancer from "fresh air".

leave it running doesn't hurt, but i tend to idle mine up a bit, to about 1000-1200 rpms to ensure significant oil gets to the top of the motor and the fan speed helps keep the temp down a bit. another thing i do is stay away from full throttle operations unless absolutely necessary. my jd 5103 max rpm is around 2300-2400. i bushhog at about 2000 (i use a 6ft b.h. model 286) and set the throttle at about 1500 when doing lite work, like box blade or landscape rake, using the foot throttle only when necessary. i have saved tons of fuel this way and some wear on the motor. i learned this from a long time diesel mechanic/dozer operator that has seen motors run like i run mine versus motors run at max rpm when working. there was a big difference in wear between the two.

I use mine mostly in winter and leave it running (at lowest rpm) for obvious reasons. In other seasons I will leave it running if it's very hot (AC) otherwise shut it off if I'll be off it more than 5 minutes or so.

You should also avoid flatulent cattle.

Thank goodness I have none of them then.

it she's warmed up, shut er down. If she's not too hot, shut er down.

I notice that cab tractor operators tend more to leave them running than open station machine drivers because weather is more of a factor with a cab. Operator station on an open tractor is not gonna get hotter or colder whether the engine is running or not so common sense is to shut it.

i always leave my 4440 running while i load silage during the winter. too hard to start on those cold mornings

No longer than 15 minutes in warm weather. In winter I never shut it down. Diesels don't like cold starts.
