Small Engines (Lawn Mowers, etc.): No Steering, steering linkage, turning in circles

Question
I have John Deer X585 Garden Tractor 4 wheel drive with Hydraulic steering.  I have lost the steer, will not turn, the steering wheel free wheels and does not come to a stop.  The wheels will not turned.  Checked and added small amount of Hydraulic fluid to proper level.  Still no go.  The tractor is stuck up on my backyard hill so it is going to be a challenge to get down as it is just turning in circles now.

Answer
Hello Tim:

If the Steering Linkage is Still Connected, then the Problem is the Control Valve is Stuck/ Broken or One of the Steering Cylinders has Blown a Seal. You can View a Breakdown/IPL of the Engine and Mower at this Site Addy, http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.H... and Enter the Model Numbers and Click Find. Then Select your Model from the Search Results Area. Then Select the Sectional File. Then Select the Section of the Mower you Wish to View Online. Check the Steering Linkage. If the Linkage is Connected, then Replace the Steering Control Valve. The Control Valve is Usually the Cause for this Problem. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck

Respectfully

John
