Life, as somebody once said, was never meant to be easy. I went to the local dealer and bought every part that could wear out in the steering linkages. Came home and set to work...No part was quite the same as on my mower, and the only part that appeared as if I might be able to install it was the triangular steering linkage and the long bush underneath it. The linkage wouldn't lift high enough without removing the motor, which I didn't want to do, and the nut on the top of the bush was of such a size that I didn't have the correct open ended spanner.
As I'm currently living in a caravan in the backyard of my sister an brother in law, I don't have all my tools, so I just tightened everything up, and decided to wait until my house is built. The question now, is do I try to change the belts to get rid of the squealing, or wait till I have a garage and a concrete pad to work on. Maybe I'll just take the seat off, and kick the hell out of the belt tensioner.
