I was looking at this earlier today, it's confusing since the pic only shows 1 tractor, no accessories, and the poster doesn't write well.
"case 446 and parts tractor rottotiller mower earth plow dozerblade 1800 obo "
Could be: Case 446 and parts. Tractor, rototiller, mower, earth plow, dozer blade. 1800 obo
or: Case 446 and parts tractor, rototiller, mower, earth plow, dozer blade. 1800 obo
Big difference, IMO. The heading is not much help either: "case 446 - $1800 (scarb)"
I see a wheel weight, and I'll assume a hitch and PTO for the tiller. May not be a terrible deal if it runs and the other pieces are in good shape.
