Junkkari's new W series combi drills have proved to be a groundbreaking addition to the wide drill market. They are based on Junkkari's familiar and precise mechanical feed mechanism, which has been paired with a new double-disc coulter design. In autumn 2020, the W700 was joined by the new W600 model. On a technical level, the newcomer with a 6-metre working width is identical to its older 7-metre sibling.
What makes the W series special is the combination of a 6–7-metre working width with a 3-metre transport width? All of this is based on an ingenious method of mechanical material transfer that has a number of clear advantages over other commonly-used technologies.
The Junkkari W series raises the bar to a new level in reliability, evenness and precision of sowing as well as cost-effectiveness.
Coulters
The W series' coulters are designed to last on large fields and function in a versatile way on different soil types and with different sowing methods. The double-disc coulters are spaced 15.9 cm apart, and coulter pressure is 20–100 kg. In autumn 2020, the coulter design was updated and the rubber suspension solution was replaced with a patented adjustable leaf spring design. This achieved an even sturdier and more durable coulter attachment and pressure mechanism.
