| I assume they are talking about a "fast valve" witch does both or a system that has an on-off and a seperate valve for metering. I have the fast valve version for Nh-3 and also on my dry spreader hyd. apron controls. Both have been trouble free. I think my 440 is a revision "F". If yours is older, you can go through the initial system set up and see if it has C-FC as an option. This tells the box it is operating the fast valve instead of the standard valves. The fast valve will require an additional fused hot wire in the harness. You can use one of the boom control wires or add an extra one. | |
