Raven has hyd kits (SmarTrax) for both these tractors, but they don't claim accuracy specs as tight as RTK from Trimble, AutoFarm, and Deere. SmarTrax takes NMEA input strings, so there are lots of options for GPS receivers that will work with the SmarTrax.
I put a SmarTrax on an 8960 this spring and was very pleased with the results pulling a field cultivator with just WAAS for position. I plan to put another SmarTrax on a 4840 this winter and use it for row-crop planting next spring, but with position data coming from my 2cm Novatel RTK receiver. Also, plan to hook the RTK to the 8960 this fall for chisel-plowing and then NH3.
Even with RTK-corrected NMEA strings being used as the SmarTrax GPS input, I have noticed that Raven is very careful when talking about pushing the accuracy of SmarTrax. At Raven Tech Conference a few weeks ago, Raven's RTK demonstration was using the FarmPRO running the AutoFarm system.
