Tractor Hydraulic System Requirements

Hydraulically driven blower requires tractor to have large oil reservoirs and increased oil cooling capacity. Load sensing or closed center hydraulic systems with flow control, deliver the oil flow needed for the blower motor to run at the selected RPMs without surging.

Tractors with open center hydraulic systems are not recommended.

Hydraulic System Requirements
Number of SCVs (min.)	3
Liters-per-Minute (Gallons-per-Minute)
Single-Rank Machine	49—57 L/m (13—15 gal/min)
Two-Rank Machine	68—76 L/m (18—20 gal/min)

IMPORTANT: In addition to these requirements, tractor MUST be equipped with a low-pressure drain line connection for the hydraulic motor case drain.

To prevent hydraulic motor damage, sump pressure MUST be less than 172 kPa (1.72 bar) (25 psi).

If your tractor is not properly equipped, see your John Deere™ dealer for installation of a Low-Pressure Drain Line Kit.

Verify that tractor hydraulic system meets all requirements.
