oregon | I have Trimble Nav 2's FMX 1000 in a 6420 and 7430 that were both Greenstar ready. For the first few years, they both operated perfectly. The base station is on a tower at my shop. The last few years, at the beginning of each pass, they tend to veer right, then swing left, then straighten out. The steering sensors on the front axle have been replaced on both tractors maybe 2X each. The GPS units are about 15 years old. Besides the steering sensors, what else might be going on? Thanks for any help. | |
