6.8 Seed coulter depth

  1. Hydraulic Controller Seed Depth: Automatic hydraulic control of seed depth on/off. When automatic mode is selected, the height is adjusted automatically to reach the target value.

  2. Seed Depth: Target value for seed depth, can only be set when hydraulic seed depth control is activated.

  3. Increment Step Size: Step size for seed depth adjustment, as described in 10.10 Seed coulter depth

  4. Align Sections: Alignment function for the seed coulter sections. For best results, run the alignment function when the machine is stationary on level ground and in seeding mode with low coulter pressure. The alignment function lifts the seed coulters to straighten the sections, which can be observed by the sensor values approaching zero. The procedure takes a few seconds. Note: This function can only be run when the machine is unfolded and the fan is running.

  5. Hydraulic Bleed: The bleeding function ensures that there is no air in the hydraulic system. Run the bleeding function when the machine is stationary on level ground and in seeding mode with low coulter pressure. The bleeding function fully retracts and extends the hydraulic cylinders in sequence. The procedure takes about a minute. Note: This function can only be run when the machine is unfolded and the fan is running.

  6. Current Height: Height sensor values for each section.
