Height Adjustment of Planting and Oscillation
The seeder has a system with jointed wheels, which allow the planting is done on uneven
ground.
This adjustment is determined by the height of the seeder comparative to the ground
surface and it can be changed by shifting the backstop position (A); while increasing its sowing
position the seeder will be closer to the work surface, thereby increasing the pressure work on the
planting lines and consequently the depth.
The different positions of the seeding over the soil surface also affect the working pressure on
the wheels. The pressure can be adjusted through tensor (B) nut and the spring (C); and tightening
the nut obtains higher pressure increasing the contact wheel with the ground, ensuring turning
traction and transmission system.
IMPORTANT
Check the spring tension of the drive wheel always occurring changes on the ad
