Hello all! Looks like a great place to consult with people! Anyhow, I have a 1996 model year Craftsman lawn tractor with a 42" cut. I cannot steer at all to the right when I turn the wheel. When I look down at the mechanism under the hood, you can clearly see that the pinion at the bottom of the shaft is "jumping" on the half moon gear when I turn the wheel. You can clearly see on the pinion that metal has been grinded away over years of use. The gears on the half moon object look a little rusted, but not stripped. What should I replace? I know its an old hand-me-down, but I am newly married and have a baby on the way and really can't afford anything real expensive! Its a strong running, decent looking mower. Any help is GREATLY appreciated!
