Yeah. Finally was able to get into the local dealer before they closed.
I explained again, that I came in, handed the sales guy the SN on the mower, and he told me I needed these connecting parts to make it work. He didn't deny it at all, but basically admitted he never ran the SN, just found the parts that a 2520 would need to have a 72" deck. I reminded him that he was the one that told me it would fit.
They basically didn't care. I'll be trying to get ahold of someone higher up, because I think it's complete BS that they only were interested in selling $800+ of connecting parts, not telling me that he didn't even check it.
By the way, I'd steer clear of Reynolds Farm Equip. It's a local branch in Mooresville, but I know they're all over Indiana.
Don't know what I can really expect, but to just say "nope, guess it doesn't work. Tough luck" is completely unacceptable. I'll be going elsewhere or ordering online.
