Just gave the mowers wash and wax jobs yesterday. Aside from paint chips here and there, they are in pretty good shape after a couple years. Since I've only had commercial equipment for a relatively short time compared to many of you, I was wondering if some of you mower veterans would care to share some other useful maintenance tips that you learned the hard way and wished you had done a better job doing when your machine was newer. (changing oil and filters is a given as well as proper greasing). I;m more interested in things beyond those items that jumped up and bit you and that could have been prevented with a little more TLC. Things like deck maintenance, grease fittings that appear to have been lubed enough, but weren't,etc.. ...thanks much.
