Not sure what kind of assembly you're referencing for the 2000, as it comes from the factory as a 3 point hitch. I believe the 1602 is a two point, meaning this poster has a conversion. I would go back to the seller. When we convert 1401s, etc. we use a hardened 3/4" (maybe even 1", I don't recall) rod, and we have never had a problem. The rod pictured looks to be much smaller, and perhaps it is soft steel as well.
