While moving around the yard trouble free for a while, the steering seems very hard to get it to move, plenty of oil and making a squeeling noise like it is low on oil. Any thoughts? Haven't touched anything to make it change.
The squealing could be from a pressure relief valve which is bypassing oil because a valve or something else isn't functioning right and restricting the flow of oil. To my ear, low oil is usually more of a whine than a squeal, but then my ears are pretty weak!
I know what you are talking about and I will check but the problem is that everything works OK until you steer it. Then the noise begins. I wonder could it be in that tiny solenoid bank of hydraulics.
