Step 2
Spray all rusted areas on the lawn mower with the solution, especially all of the parts pertaining to wheel height adjustment. Allowing 5 - 15 minutes for the solution to eat into the rust will usually be long enough.

Step 3
With a little luck, now you can adjust the wheel heights. If not, get a good pair of vice grips or a large pair of channel locks. Force pry open the adjustments and move to a different height slot. Spraying more of the vinegar and Mystery oil mixture, at this time, may be needed. Then move the adjusters from minimum to maximum height a few times.
