Hello first message here about my lawn mower,

I'd like to see if someone could tell me where to start my investigation to locate a faulty part on my L110. (the high-pitched sound that resembles a cricket)

I recorded a chipping sound it's producing when the blades are engaged only. it looks like it's coming from the engine directly. That sound starts after maybe 10 minutes of using the mower, it needs to be hot. That problem is 4 years old at least but it needs to be addressed now.

Hopefully a trained ear could point to me the right direction of what to investigate first.

NOTE: The safety switch I taped to record the video is back to original now, tractor is back to it's safe state.

This is the audio video recording.

Thanks in advance.
 
I hear it.
With the blades engaged, all pulleys and belt are turning. Those are the parts that need to be checked.
Start be removing the belt and inspect the belt.
While the belt is off, check the idler pulleys and spindle pulleys. Do they spin without noise or play up and down and side to side?
Engage the PTO without the belt on. Is the noise still present?
 
Thank you for your help and for listening to the video and audio.

Engaging the PTO with the deck off, I hadn't thought of trying that. I will remove the deck tomorrow and investigate the pulleys and spindle pulleys. The strap is fairly new, 3 seasons it looks news but i'll inspect it too.

When I think about this, that noise started +- with the replacement of that strap... 🤔

I'll publish a picture of it here.

The belt may look new. However, three seasons may have taken it's toll on the belt. There could be a piece of rubber missing.
