The whole storing tractors outside whilst waiting for sale gives me some problems.
On the one hand, cars and trucks are pretty much always stored outside. They don't seem to rust. People park their cars outside for years without material rust on them. Why should a tractor be more prone to rust? Are they just poorly made?
On the other hand, tractor models change less frequently, and some models and some dealers turn over very slowly. A tractor can be a year or two on the lot and still sold as new.
And I don't get why a tractor, which is a heavy duty machine made to work in dirty and damaging conditions, should rust. Looking at your photos, most of the tractor didn't rust. Then a few bits did. What's different about those bits? Why do you make a loader that's all painted or chromed, and then the pins are some sort of mild steel that just rusts out? Seems like you've done 90% of the job, then said "hey, let's just chuck these pins in, so long as the loader itself is shiny nobody'll mind if the pins rust." Why do you have an engine that's all steel and didn't rust, and then there's a shine plate that looks like stainless or chrome at least, and it rusts. What goes on for this to happen?
I would have thought plenty of guys store their tractors outside - not everyone has a shed. And they don't expect them to rust like that, surely?
Bottom line, when I finally get my B2601 (my first brand new tractor), I'll be asking for an actual new one that comes on a truck and they assemble it then deliver it to me. Not a "new" one that nobody's owned before, but has sat on the lot for a couple of years.
