If there's no fluid coming from your steering cylinder I wouldn't think that was the problem.. Id be more willing to bet that your power steering box gave out, or flow divider valve. You'll have to just do some tests to find out for sure what it is. If you wanna give me a call i can walk you through it and find out what is going on. Ive also got a very experienced mechanic in the shop that knows these tractors inside and out. Feel free to give me a call!
