Hello, I'm new here and joined to get some help. Although I hope to buy a tractor in the future, right now I am borrowing my friends Toolcat 5600. I was using it today to move some dirt, while in 4 wheel steering, I made a turn after dumping, and the steering stopped all together. I can turn the steering wheel in either direction as much as I please and no movement what so ever. all the tires are at close to max turn so I can't try and put it into 2 wheel drive. All the hydraulics work i.e. bucket and bed, but the steering. when turning the wheel, at a couple points in sounds almost like it is binding for a second and then is free again, when it does make the "binding" sound, the wheels seem to momentarily move until the "binding" sound is gone. Any ideas on what this might be would be greatly appreciated! I look forward to hearing from you.
