Cedar Rapids, Iowa | Ours is individual boxes with finger units, pulled by a MX275
It has the super single transport tires. The issue is when the transport axle is on higher ground than the regular wheels. To fold the planter up, normally we lower the transport axle until it has the center weight, then bring the wings in. In the case where the transport axle is on higher dirt, it has the weight, but still isn't low enough for the tire to clear under the frame of the wings. Here is a picture with the transport axle at the proper height:

The hydraulic drive issue is 100% a poorly written control loop in the software. It uses the GPS speed data as the primary source of speed, while GPS has a well known lag on changes in speed. Speed data is also jumpy, so it has to be smoothed in software, which adds to the lag. The result is a 1.5 to 2 second delay on speed, which causes the population to get quite ugly at times, both over and under populated. Secondly, there is a "backup" speed sensor on one of the wheels, but it appears that it is only used when the GPS speed data is unavailable. The system should have been designed to use the wheel sensor as the primary speed source and to use the GPS to auto-calibrate the wheel sensor. In addition to all that, it will throw random fits where it just won't work. Rebooting everything seems to cure that most of the time. | |

Does anyone have anything good to say about Kinze 3800s these days?
