Ok, my brother-in-law picked up a used Dixon 30" mower at an auction with a nice little 12hp Briggs for his small yard. It runs like a top, but it doesn't steer woth a darn. Now I have scoured the internet for cone adjustment, but it just isn't there. Amazing. Must be a million of these little mowers on the planet, yet how to adjust the drive must be the best kept repairman secret ever kept. So the question is, does anyone here know how to adjust them, and would you be willing to share the procedure please.
