Thanks for the info. Your drive system on this machine is hydrostatic as you know so if you are pushing strong but not steering it means you likely have a pilot control valve problem not signalling the pumps for steering or a potential pump problem. Click on this link to see the breakdown of the travel circuit. Check the filters for signs of fine metal/debris indicating a pump or component failure occurring. It will look like fine metallic glitter if present. If the filter and oil are clean I would check the pilot control valve for problems and have your pressures tested to isolate if it is in the valve not signalling pilot pressure for steering or a loss of pilot/signal pressure.
