I need a mower deck for an A/C B-207. If I knew what to search for I would search for A/C and Simplicity. I'm sure the answer is hiding in plain sight, but the cross reference charts I have seen don't even list the B-207. So, where am I going wrong, and what Simplicity tractor is similar to the B-207? I also need the corrugated grill screen for that tractor.
