Tramlining flaps
Tramlining is carried out by the spring loaded tramlining flaps (A) which are integrated into the
outlets of the seed distributor heads in the seed hopper. In the activated position (Position 1) the
flaps are raised into place to close the outlet while opening a trap to allow seed to return to the
hopper
.
The flaps are controlled by a spring (B) on a motor driven disc (C) under the distributor head. The
electric motor has three connections to the Control box: An earth, an ON signal and an OFF signal.
Check the function of the tramlining system at the start of the season and at regular intervals
throughout the season, see
”3.2 Checking the seed feed” on page 65.
