I have noticed one issue on NH & CIH vehicles with IntelliSteer or AccuGuide Steering. Since moving to v30 software on the IV4/Pro700 I have trained our techs to delete the vehicle profile saved in the Nav Calibrations tab. This is the vehicle profile that loads steering performance settings on start up and saves on shut down - since deleting the vehicle profile and re-calibrating guidance using the new Advanced Line Acquisition (ALA) it became a game changer on T7/T8/T9 so should see the same with Puma/Magnum/Steiger. I have noticed poor performance when on v30.x software with ALA and is using the old vehicle profile which could be from v27 or v28.

Create a new profile Calibrations > NAV > Vehicle Model

Delete old profile Data Management > Delete > Data Type > Stored Name > choose old profile

The import things to confirm:

Toolbox > Nav-P - Set Performance Mode to Advanced

Standard Mode: Gets the nose of the tractor online
Takes longer to get a rear-mounted/trailing implement online.

Advanced Mode: Gets the hitch online
Means the nose of the tractor may appear to not acquire the line quickly (overshoot). Perfect in my region.

Adjust the following settings to your vehicle and IMPLEMENT (People forget about implement as draft loads are different)

• Aggressiveness – How quickly the tractor will steer to keep the vehicle on-line during automatic operation. A higher value results in a faster, more abrupt steering response.

• Initial Turn Aggressiveness – Controls how the vehicle steers toward the swath relative to how it turns ONTO the swath. Set the Maximum Approach Angle first, then adjust Initial Turn Aggressiveness as desired. A high value will cause the vehicle to turn more sharply toward the active swath, to achieve a value within the Maximum Approach Angle. A lower value will result in a more gradual turn toward the active swath.

• Maximum Approach Angle - Defines the angle the vehicle uses to approach the active swath after the engage button is pressed. A value of 20 means that the vehicle will approach the line at an angle of no more than 20 degrees, for a very gradual approach. A value of 90 means that the vehicle will approach the line at an angle up to 90 degrees.

• Maximum Steering Angle - Defines the maximum angle to be steered by the steerable axle when acquiring a swath. The Maximum Steering Angle must fall within the physical steering limitation of the vehicle. To obtain the Maximum Steering Angle, reference the value displayed in the sensor calibration in the calibrations menu. This parameter is visible, but not used, on vehicles equipped with Autosense. A high value will allow the vehicle to turn more sharply (within the physical steering limits) toward the active swath, to achieve a value within the Maximum Approach Angle. A lower value will result in a more gradual turn toward the active swath.

• Maximum Slew Rate - Defines the commanded steering rate in degrees per second. The Maximum Slew Rate must fall within the physical capabilities of the vehicle, and is dependent on vehicle model, specific steering valve, etc. The default value will provide acceptable performance on the majority of vehicles. Adjust only if necessary. A high value (more degrees per second) will command faster steering. A low value (fewer degrees per second) will command slower steering.

• High Speed Maximum Angle - Sets the ground speed at which the Maximum Steering Angle begins to decrease for a more comfortable ride during swath acquisition. The default value will provide acceptable performance on the majority of vehicles. Exceeding the High Speed threshold will degrade performance. This parameter is visible, but not used, on vehicles equipped with Autosense. A high speed will allow the vehicle to use the standard Maximum Steering Angle during the majority of field operations. A low speed will cause the Maximum Steering Angle to degrade quickly, potentially even at normal operating speeds.

• High Speed Maximum Slew Rate - Sets the ground speed at which the Maximum Slew Rate begins to decrease for a more comfortable ride during swath acquisition. The default value will provide acceptable performance on the majority of vehicles. Exceeding the High Speed threshold will degrade performance. A high speed will allow the vehicle to use the standard Maximum Slew Rate during the majority of field operations. A low speed will cause the Maximum Slew Rate to degrade quickly, potentially even at normal operating speeds.

Hope this helps.
