Service Air Conditioner—If Equipped

Check the following if air conditioner will not cool, or if cooling is intermittent:

  1. CAUTION: Refrigerant is under pressure. Improper servicing may cause refrigerant to penetrate eyes and skin or cause burns.

    IMPORTANT: R134a refrigerant must be used. This requires special equipment and procedures. See your John Deere dealer.

    NOTE: Some oil seepage from compressor shaft seal, on the lower front, is normal.

    If air conditioner clutch slips after tractor has been in storage, compressor may be stuck.

    1. Place tractor in PARK position and SHUT OFF engine. Remove key.

    2. Raise hood and remove fan belt. (Refer to Replace Fan Belt—5065M and 5075M or Replace Fan Belt—5085M, 5095M, 5095MH and 5105M in this section.)

    3. Rotate clutch hub back and forth to free compressor.

    4. Install fan belt and lower hood. (Refer to Replace Fan Belt—5065M and 5075M or Replace Fan Belt—5085M, 5095M, 5095MH and 5105M in this section.)



  2. Run engine at 2000 rpm. Push top half of A/C and defrost switch (C) and set blower control knob (B) to HIGH position (A). If cooling is intermittent, clean front grille, radiator and condenser. (See Clean Grille Screens, Radiator, Oil Cooler—If Equipped in this section. If problem is not solved, see your John Deere dealer.)

  3. Inspect operator enclosure (cab) filters for restriction. Clean filters. (See Clean Cab Air Filters—If Equipped in Section 41.) If problem persists, see your John Deere dealer to have evaporator core cleaned.
