Looks like you are asking for a good place to buy parts. This all depends what parts you are looking for and how soon you need them. Common parts like filters, oil, plugs, etc any good auto parts store. Brand name engine or chassis parts would be a dealer. I will often look at salvage yards for used parts to save money. Also don't forget Ebay for bearing and seals.
i see you have a craftsman mower. sears parts direct is great for that. they still make parts for my gramps crafstman lawn tractor which is a 1983 or 1987. cant remember the year. its one or the other but still, thats pretty old to still have parts and manuals for!:biggrin:
OK seriously...what is wrong with these posts? Multiple people have tried to make a post with that title and it won't let them. Is it the automatic spam thing that won't let them post it? If a moderator can explain this that would be great. I mean, just look at these threads that don't work!
