I was a JD parts manager for several years and just took my mower to our shop because the work and parts were done at cost. Now that I would like to save some of that expense I want to do the preseason work myself. I have a bearing vibrating, and it is time to change belts while I have it apart. I just want some do-it-yourselfers to chime in with some tips to keep from making the first timers mistakes in disassembly/reassembly. Thanks
