Junkkari has for a long time produced successfully mechanical combi drills in 2,5-4,0m working widths. With this over 60 years' experience we are real specialists in this business.

During the years farms in Finland have been growing and we have also found new export markets especially in Eastern Europe. There has been more and more demand for bigger machines and that is why we developed our W-series. We wanted to introduce same reliable and precise mechanical technology in much bigger scale but with compact transport dimensions and foldable design.

After launch in 2017 Agritechnica, Junkkari's 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.

1. RELIABLE AND EASY TO USE AND MAINTAIN

• Power transfer to the feeding mechanism comes from the roller wheels, with the exception of the fertilizer conveyor screws. The drill only requires 20 l/min of hydraulic flow during use, which is needed by the conveyor screws.

• The design is simple and reliable. It does not include too complicated hydraulics or electronics.

2. PRECISE

• Even feeding in terms of both width and distance. Every coulter has its own feeding mechanism.

• No delay – the mechanism only feeds when the drill's wheels are turning. No overlap or unsowed spots.

• Separate drive on each side increases precision while turning.

• A new double-disc coulter design deposits seeds and fertilizer at precisely the desired depth on all soil types. The pressure is created with patented, adjustable leaf-spring system.

3. ECONOMICAL

• Does not have as high requirements for the tractor as its pneumatic competitors 

• Does not require a continuously variable transmission, variable displacement hydraulics or the continuous generation of significant hydraulic pressure.

• Requires significantly less power than its competitors, thanks to mechanical screw system without fans, large wheels, and low-drag coulters.

4. EFFICIENT

• Large hoppers mean less time spent on filling and logistics.

• The low power draw and mechanical feeding mechanism allows for a fast sowing speed without an upper limit.

• Combi coulter for seed and fertilizer means less parts in the soil

In general, Junkkari W-series is excellent choice for those who are looking for efficient, precise, easy to use and reliable drill in 6-7m category.  It is different than competitors, but it is still based on very familiar and proven technology.
