Did not see a whole lot out there when I searched on this topic so since its bound to come up, thought maybe we could start one here that would be easy to find when a search is asked for. I can do the "routine" stuff like lube and oil stuff but would like to hear what you experienced commercial equipment wrench heads have found works well in winterizing your mowers(whatever kind) and the 2 cycle equipment. Heres something I learned this weekend...trailer tires are subjected to more neglect than the tires on our trucks and cars...beacause at least on those, we occasionally spray on some tire dressing/Armorall etc. This prevents dry rot which is actually caused by UV rays not rain/snow/cold/air.....so he says we should spray them occasioanllay with Armorall/STP and then cover them when the trlr is inoperable for a month or so...now I understand why the big RV's often have tire covers on when parked.....ok so much for trivia you couldnt care less about!! Just thought UV thing was interesting....and anyway we can save costs is good.
