An iGrade™ leveling system activation works with many of the different John Deere Precision Ag Technology components that producers may already own such as:

G5/G5^Plus CommandCenter™ and Universal Display
4600 CommandCenter Display/4640 Universal Display
4200 CommandCenter Display/4240 Universal Display
GreenStar™ 3 2630 Display
StarFire™ 3000 Receiver, StarFire 6000 Receiver, StarFire 7000 Receiver, and StarFire 7500 Receiver
AutoTrac™ assisted steering system
Surface Water Pro™ Plus software on GreenStar 3 2630 and GreenStar 2 2600 Displays only

It requires a vehicle global positioning system (GPS) only; the receiver must have an SF2 or greater signal level.

NOTE: Do not mismatch generations. If a StarFire 3000 is used on the machine, a StarFire 3000 must be used on the implement if utilizing a second receiver for specific operation.

iGrade is approved for the following platforms:

iGrade requires the receiver to have an RTK signal level. iGrade does not support WAAS, EGNOS, SF1, SF2, or SF3 signal levels.

The John Deere Application Controller 1100 is required for iGrade activation.

Harness compatibility

UCC2 Application Controller 1100 (serial number PCXL01C201000+) is not compatible with original UCC1 Application Controller 1100 harnessing. Plugging the UCC2 controller into UCC1 harnessing will cause CAN bus issues due to no terminator in the circuit.

Harness options

Ensure UCC2 main harness PFA11888 is used with the UCC2 Application Controller and replaces the existing harness connection. Adaptor harness schematics are available in the Technical Manual to create a wiring adaptor from UCC2 Application Controller 1100 to the existing harnessing from a UCC1 system.
