Connecting Hydraulic Hoses-9000 Series Row-Crop Tractors

causym CAUTION: To avoid injury from escaping hydraulic oil under pressure, relieve the pressure in the system by shutting off tractor and moving SCV levers in both directions before detaching hoses from the breakaway couplers.

Hydraulic hoses can fail due to physical damage, kinks, age and exposure. Check hoses regularly. Replace damaged hoses.

IMPORTANT:

  • 9000 Series tractors require a special tip to be installed on the case drain hose. Part number for tip is AA59412.
  • Case drain hose (A) must be connected to tractor OR placed in storage bracket (C) at ALL times to prevent damage to CCS fan and vacuum motor seals.
  • Fan motor/vacuum motor case drain hose MUST be attached to low-pressure drain connection PRIOR to inlet and return hoses being connected. Case drain MUST have LESS THAN 172 kPa (1.72 bar) (25 psi) or fan motor will be damaged.
  • Installation of a Low-Pressure Drain Line Kit is required if towing tractor is not so equipped. Refer to PROTECTING HYDRAULIC MOTOR SEALS-LOW-PRESSURE (CASE) DRAIN CONNECTION in Preparing Tractor section for appropriate kit.
  • DO NOT USE other ports at the rear of the tractor (such as power-beyond ports) which may be similar in appearance and size to low-pressure drain port. Due to high back-pressure (over 172 kPa [1.72 bar] [25 psi]), drain connection to these ports WILL RESULT in fan motor damage.

1. Attach case drain hose (A) to low-pressure drain coupler (B).
