Hydraulic Marker (Mark Scriber) Mechanism

Seed Drill Hydraulic Marker (Mark Scriber) Mechanism
It is the mechanism that marks the field in order to show us from where we should drive tractor by the best way according to the previous line. System runs by a pressure hydraulic command which will be given to two hydraulic hoses to be connected to the hydraulic pump outlet of the tractor. There are two markers on the right and left sides commanded by this system. When levers are pulled down, intended mark drawings will be formed by the discs on the end of these handles. During the first operating, our authorized service will explain how you can command it to marker levers. In the following, it is explained how the length of lever is adjusted.

It is required to calculate length of marker lever according to distance of front wheels of tractor to which the seed drill is attached. After calculating the length of marker lever, setting fixing bolts on the lever are loosened and then fixed after adjusting the length, and are operational. During planting, at the end of the row, it is required to fall the lever on the side where you will turn and then cause to line drawing. When each new line is planted, it is ensured that the wheel, which is close to the side where we turned, is able to pass on the mark lined previously.

Seed Drill Hydraulic Marker (Mark Scriber) Mechanism
M= Distance from the middle of tractor to the marker edge of the drill.
G= Working width of the seed drill.
T= Distance of the front wheels of the tractor. (From mid point to mid point)

M= G – (T/2)

For example: What should be the marker length in case we want to drill wheat with a 3m wide seed drill?

Assume that the distance of the wheels of your tractor is 160 cm from mid point to mid point.

M= 300 (cm) – (160/2)
M= 300 – 80 = 220 cm should be the distance from middle of the drill to the point that the marker disc touches the ground.
