John Deere 3038E idling
I bought a new John Deere 3038E last summer and have seen several mentions of letting the tractor idling before turning it off. Will this really provide long tractor life?
Yes, the problem is the turbo. It will get quite hot as it feeds off the exhaust gases. Therefore, after running hard, you have to let it idle for a couple of minutes. Otherwise, it will end up failing earlier than normal.
I usually leave the engine idling for the last 200 minutes of driving to park it. If it is a hot day and I have made it work a lot, like when I mow the lawn in summer. I let it idle for longer as it gets hotter. I usually take that opportunity to grab the blower and blow out the radiator. So more like 5 minute cool down.
What happens is this: The turbo depends on the circulation of the engine oil for lubrication, which only happens when the engine is running. When turned off in a hot turbo, the remaining oil is trapped, and it quickly cooks and forms carbon deposits because the hot turbo keeps spinning. Over time, these deposits will destroy it. The reason to idle it is to cool it down so that trapped oil doesn’t burn.
People say tractor turbos are super reliable, never have to worry about them, etc. I think that’s only true due to the relatively low usage compared to something like tractor trailers (which typically spend 10-15,000 hours before being rebuilt, if not longer). So I’m not even sure doing this is a big deal with tractors.
They just aren’t used enough. I would still do it religiously if I had a turbo because I just can’t bear the thought of damaging my gear (and this is one of the reasons I don’t). Not being able to turn off the engine in the middle of work without feeling like I’m doing something wrong would quickly get old.-то не так, это быстро устареет.
