No
I always run across the trays with a new fert and the results from the shaker box and online charts aren't usually far away but definitely not always right
No it's still the same system you still need to establish a letter to set the spread width then the section control works from therethanks for that, take it there's a chart to look up then to reference spread width gearbox speed and material quality, on the older ones you have that 4 section box that you fill and shake then read off the results and set the drop point accordingly, which can be the weak link in the system, does the new system do away with that?
