What are the improvements in a series 2 verses series 1 SuperM backhoe?
There isn’t any series 1. The first production release was a 580SM. The second release was the series 2. Just those two ? There are 5 different 580SM’s. They all have different parts books. The dealer handout brochures may indicate the changes that were made in them. I think it was mostly the motors in them and the associated emission equipment.
