Minnesota | We purchased a 2017 580 quadtrac that has about 2000 hours. This is my first machine with a 2 stage turbo and first tier 4b tractor.
We will sometimes get a air hissing noise coming from the turbo area under the hood....sounds like an air leak from the turbo. It only does it with very light engine loads -- like turning at the end of the field or driving through the yard. The hissing noise goes away as soon as we put some load on the engine -- like pulling through the field or even throttling up the engine. It might do this for 30 minutes and then not again for a couple hours or maybe not again for the rest of the day. I don't think that there is a blown line since the noise comes and then goes away after a while.
I can't find any loose air lines/clamps and the tractor seems to run just fine. Is this just a quirk of the two stage turbo or something with the DEF system or a symptom of some type of turbo problem? | |
