I recently had my tw20 at the dealer to get the steering motor rebuilt. It was working yet leaked. When they took it apart the main shaft was worn so bad that a new motor was needed, the choice was new for $1700.00 or used and rebuilt for $500 plus parts and labor. So I opted for the used. When the tractor was done I went to get it. I went to move the tractor and noticed how hard the steering was. Thought well it is cold outside, maybe it will warm up and steer smoothly. I could usually steer the tractor with one finger. Now I have to grip and pull. So I called the dealer, told him how stiff it was. He said it was probably the spindles. I told him I wouldn't be driving the tractor till spring. He said he would stand behind it. I don't think it is the spindles, cause it turned easy before they worked on it. Any ideas of what could be wrong with the rebuild? Thanks
