I bought the Ryobi 40V riding mower in 2019. It started squeaking after 2-3 hours use. Even after following the cryptic lube instructions in the manual, the squeak persists. I have resorted to wearing earbuds and listening to music.
I am planning light disassembly this spring to look for loose screws, bolts and metal to metal wear. Will also be using a heavier grease.
I will revert if I can solve for this maddening noise! 😡 Not that anyone asked but I would not recommend this "$3k Squeaker"
