Bearing noise ?

[Ed Kennell 42,081]

After mowing with the 312H tonight I left the motor running and started to hose off the grass when I heard this high pitched bearing squealing noise.   I turned off the hose and walked around the tractor but could not pinpoint the source of the noise.      So I turned off the engine and the squealing noise continued.

Found it.....a swarm of  cicadas in the locust tree I parked under.

Several years ago I bicycled thru Missouri in May.  We had to listen these things for miles on end and for at least 3 days.  At first they sounded like a string trimmer.  The intensity increased from there and it became like a circular saw.  When we crossed the Mississippi into Illinois it stopped and there were dead bugs crunching under our tires.  Didn't miss those suckers at all

So...maybe a bad bearing in a 312H sounds like a bunch of cicadas???  Ed, we need a video with a sound track so we can help other members.

Must have been the 7 year locust you experienced. Those things drive us crazy in Iowa as well.

Here ya go Steve.

There is a seven year and a seventeen year locust Doug.       And when their life cycles fall on the same year the numbers are enormous.
