  • Lawn Tractor Linkage Repair

    The linkage that controls the height of the front of the mower deck on my friend’s church tractor, fell off. It got caught in the lawn and created a lever, which the tractor used to snap off the linkage at the necked down area of the shaft. My friend hunted around the lawn and found the long bent part of the linkage, but couldn’t find the short threaded end. I replaced the missing part with the shaft portion of a 7/16” bolt. The bolt was zinc plated so I had to soak it in Hydrochloric acid (Muriatic acid) to remove the zinc before welding.

    That is why one pays the extra dollars for a John Deere....

          Here are links to other repairs that I have made to it over the years:


          It is hard to see, but this is where the repaired linkage goes:
