Deere knew by marrying the controls with the seat that the seat would require more adjustability. At this point, other modifications were made, such as moving the float switches, and properly metering the hydraulic valves in order to adjust the lever feel. The GP models (Deere also offers traditional controls on its G-Series machines) have a grade control intergration system that gives customers their choice of using either a Topcon or Trimble system. Designers knew these systems would come with a monitor, creating a visibility problem if it was mounted to the side of the grader system monitor. So Deere put redundant wiring in the cab's right hand post, which allows customers to reposition the vehicle monitoring system there, allowing for the grade control system in the original monitor position. Standard on GP models is automated cross-slope, which simplifies holding a consistent slope by reducing operation to a single lever.
