I have a brand new Kubota 4060 with cab. It has only one problem. Under way it sounds like someone is trying to hacksaw off the roof of the cab. My old open deck tractor was quieter to operate. I’ve pushed and wiggled everything and used silicon spray on anything that moves. I’ve re-greased all the fitting, etc. Do all cab tractors squeak? At first I thought it was the seat springs but now I don’t know.
