A seeding table is located at the end of the seed drill box which indicates example values for seeding volume adjustments. However, there are sig- nificant differences in seeds in terms of size, weight and flow, because of which the actual seeding volume must be verified through calibration.

  • Page 48: Calibration Using An Electronic Volume Control

    Depending on the control unit, an electronic volume control for seeds and fertilisers is available for Junkkari seed drills as optional equipment. This allows the seeding volume to be adjusted while driving using the seed drill control unit. The calibration of a new machine should be repeated at least four times if the basic factory setting differs significantly from the calibration result.

  • Page 80: Seeding

    SeeDing 12 SeeDing Using a new seed drill, seeding should first be tested without any seeds or fertilisers. This is impor- tant because it allows you to test the machine and control unit, and to learn machine adjustments well before the busy seeding season. 12.1 Start oF SeeDing Make sure that moving machine parts do not cause injuries to people or damage to property close to the machine.

  • Page 81: Fertilisation

    SeeDing •   Moist conditions: When preparing for moist conditions, the land may need to be cultivated deeper to increase the water space. It is especially important for the growth capacity and struc- ture of soil that it is not trampled or cultivated when wet, and that machine surface pressures are as low as possible.
