Odd- and Even-Numbered Tramline Rhythms
The rhythm may be based on an odd or even number, or on a number plus remainder. Each different rhythm necessitates a different tramlining procedure.
Tramlining rhythms based on an even number necessitate travel in two directions (outward and return). Rhythms requiring travel in only one direction are however more accurate than those requiring travel in two directions.
A recommended solution is the use of even-numbered symmetrical "S" rhythms (e.g. 4S, 6S etc.) which can be used to produce tramlines in just one direction of travel. In this case you must commence by sowing with just half of the working width of the drill or you must shut off the corresponding partial width of the crop sprayer or fertilizer spreader. Then proceed as though you were working with an odd-numbered rhythm.
Tramlining with an odd-numbered rhythm (e.g. 3, 5, 7 etc.) necessitates travel in only one direction.
Rhythms 2, 10, 12 and any rhythm with a remainder may be produced only with the aid of the Signus/GreenStar

seed-drill control. See Signus Seed Drill Monitor System section.
