Depth Adjustment Mechanism and Travelling/Working Positions of Coulters
Seeding depth adjustment and switching the coulters to
travelling position are realized with the depth adjustment
mechanism deployed at the center of the grain drill.

C.2.1 Depth Adjustment Mechanism
The depth adjustment mechanism is a double-drive
hydraulic lift with the lower part is connected to the coulter
frame via coulter frame connecting bushings, and
connected to the main frame via frame connecting
bushings from the lift center, and having a limiting
mechanism on top part.
The stroke of the depth adjustment lift is provided by the
depth adjustment rings on the top. Depending on the
coulter and frame slope, each ring provides a seeding
depth of 1 cm.
