The very newest NH tractors have the ability to allow the Nav-900 (with GFX-350/750) to plug into the CAN system of the tractor. This bypasses the need for the legacy NAVIII controller that is need for vehicles without that CAN plug in. The NAVIII has a valve driver for hydraulic control and the Nav900 does not. Trimble is coming out with a "valve driver" module that will connect to the Nav-900 that will be about half the cost of a NavIII. This will allow you to use the Nav-900 for its gyro sensors and communicate its valve driving to the steering valve without having to purchase a NavIII.... but today you would have to buy a Nav III for an older style AP install. Valve driver should be available Q2 21' i have heard.Yes a separate nav controller. Was told unless it was a very late model New Holland I still needed a separate nav controller. Which is very expensive
Fieldbee doesn't use lightbar, it shows how many cm you have to adjust left/right to drive on the perfect line.I don’t get why you need rtk on a light bar. You can’t drive to 1-2cm accuracy by hand
Agricision claim 30 cm I think.How accurate is the Agricision device?
I'm after a second budget GPS, because I am fed up with constantly moving Mojomini from sprayer to spreader tractors, etc, and am concerned that Mojomini will suddenly die one day and leave me looking for something in a hurry.
I wouldnt want to buy something less than 0.5m accuracy bout to bout, which is probably an honest assessment of what I have now, and adequate for fert and grass spraying.
