IMPORTANT:
Do not use an open center tractor hydraulic system to operate machine. Permanent damage to tractor pump can result.
For complete tractor operating instructions, refer to the tractor operator's manual.
The vacuum motor and variable rate drive hydraulic systems are designed to be operated with closed-center tractor hydraulic systems. Tractors with load sensing or pressure on-demand hydraulics are
|
classified as closed-center systems. Open center tractor hydraulics are NOT compatible with this system.
Minimum required tractor standby pressure is approximately 15 513 kPa (155 bar) (2250 psi) depending on frame configuration, planting speed, and number of rows.
Hydraulic system working pressure is 20 684 kPa (207 bar) (3000 psi). Hydraulic system burst pressure is 82 737 kPa (827 bar) (12 000 psi).
