Every part of the metering system is precision engineered and then precision manufactured to ensure accurate seed singulation every time you plant.
Unlike a cup or belt metering system for round seed, the flat surface of the Monosem stainless steel seed disc allows even the most irregular seed shape to be suctioned and gently held to the disc.
Seed discs are available from: 18-30, 36-60, 72-90, 120-180 holes; hole sizes from .5- .6- .65- .7- .8- .9- 1- 1.2- 1.5- 1.8- 2- 2.5- mm. Custom seed discs available for twin lines and hill dropping.
Planting Double Line Crops
The MS metering boxes can plant in single line as well as double lines. For this, the single line shoe is simply replaced by a double line shoe, the disc with one line of holes is replaced by a disc with 2 lines of holes and a 2nd selector is added.
