I'm looking for advice anyone may have on this -

I have a snowizard machine and it works great, this is my second season with it. Just recently I've noticed a short squeaking noise (I've convinced myself that its the belt) after I turn it off. Today I changed the blades and have noticed another noise. Today when the machine is turned on there is a higher pitched squeak. The machine seems to be running fine but I am a bit worried that these squeaks could manifest into something that would keep me closed until its resolved.

Any help would be appreciated!
