*all weights & transport dimensions are estimates & are subject to change. Every effort has been made to ensure that the information is accurate/current at the time of production.
For 100' units, especially 10" spaced units - 7/8" ID tertiary lines unless seeding large pulses.
For 80' units, especially 12" spaced units - 1" tertiary lines.
Recommended Flow Requirements:
Hydraulic flow requirements are highest when turning on the headlands. The recommended flow allows the seeding system to be raised and lowered within two headlands. It should be noted that the recommended fan requirements are for the maximum operational speed (RPM) of the fan.
Minimum Hydraulic Flow Requirements:
Recommended hydraulic flow should provide minimal fan slowdown during headland turns. The openers will take hydraulic flow priority over the fans.
If operating at minimum flow requirements, the air seeder fans will drop a minimum of 20% during headland turns. This may require a 3rd headland to allow the openers time to raise and lower.
In typical operating conditions one or both fans are operating at less than maximum output levels, which will reduce hydraulic requirements.

With many tractors, maximum hydraulic flow drops off sharply prior to maximum operating pressure. By setting the tractor to a pressure setting of 3100 psi the hydraulic flow will be near the rated output at the maximum operating pressure.
The 3420 Paralink Hoe Drill requires a minimum hydraulic operating pressure of 2800 psi.
