OEM on the cab YT359C are CAT1. Spending a lot of time looking at implement weights and units that have both CAT 1 and 2 options on attachment pins. Still, making sure the swing arm adjustments are all the way pulled in and set with the drop pin holder on the left side and right side is the only catch. If you mess up and forget the arms will drag on the tread of the tire. Arggghhhh.
