Seed placement with ProSeries™ Opener 1590 Series down pressure
ProSeries single-disk no-till openers are included in base equipment. The single-disk openers are mounted on one rank on the 38.1-cm (15-in.) row spacing single rank units and on two ranks on the 19-cm (7.5-in.) and 25.4-cm (10-in.) row-spacing units. The single-disk openers provide consistent and accurate seed placement.
The single-disk openers are gang mounted and are hydraulically raised and lowered. The hydraulics also work to provide a wide range of downforce settings for the openers.
The active hydraulics work in conjunction with the opener spring to provide an adjustable range of 74.8 kg to 181.4 kg (165 lb to 400 lb) of down pressure per opener to penetrate hard soils and heavy residue.
The down pressure is easily adjusted with the pressure valve located on the front of the mainframe, giving the operator the ability to quickly adjust, or dial in, the down pressure as operating conditions change.
For additional ballast in hard-to-penetrate conditions, tractor suitcase weights may also be added to obtain maximum down pressure per opener. On the 3.05-m (10-ft) and 4.6-m (15-ft) machines, up to 10 weights can be added. On 6.1-m (20-ft) machines, up to 20 weights can be added (10 per side).
The no-till openers work not only in no-till conditions, but also in clean-till conditions. There are 5.1 cm (2 in.) of free travel in the opener before spring down pressure takes over, allowing the opener to move over individual rocks and minimizing the chance of the gauge wheels bulldozing soil in soft or mellow conditions.
Secondly, the opener spring will then travel a maximum of 20.3 cm (8 in.) up or 15.2 cm (6 in.) down before the hydraulics react to uneven seedbeds.
Lastly, the cylinders will allow the openers to travel up or down an additional 40.6 cm (16 in.) with active hydraulic down pressure to follow the ground. The hydraulics will give the openers additional pressure when needed or allow the openers to go into relief if the pressure becomes too high.
