What to do if the pressure gauge reading is higher than actual pressure on ARAG Farm Equipment?
- G
  Grace GarrisonAug 17, 2025
  If your pressure gauge reads higher than the actual pressure, it could be due to a malfunctioning pressure gauge (change the pressure gauge), a squashed gasket inside the pressure gauge partially obstructing the passage (slightly loosen the pressure gauge), or undersized passages across the valve and nozzle, leading to a significant pressure drop (choose section valve tubes and hose tails of the correct size).

What to do if the pressure cannot be lowered with the proportional valve switch on the ARAG 463 Farm Equipment?
- L
  lharperAug 21, 2025
  If the pressure cannot be lowered, it might be due to a non-working proportional valve motor. Check the electrical connection: the cable marked “P” must be connected to the proportional valve (yellow or grey collar). Also, the proportional valve drain passage might be clogged (clean the drain passage), or a hydraulic agitator might be connected to the drain passage of the proportional valve (remove the hydraulic agitator and leave the hole open). The drain tube of the proportional valve might be undersized (change the drain tube), or the proportional valve flow rate might be lower than the desired rate setting (change the proportional valve). If the motor is faulty, have the gearmotor inspected at the nearest Service Centre.

What to do if the pressure transducer reading is higher than actual pressure on ARAG Farm Equipment?
- A
  adamsphillipAug 25, 2025
  If the pressure transducer reading is higher than the actual pressure, the transducer might be malfunctioning (change data settings in computer; if problem persists, change transducer) or the passages across the valve and nozzle might be undersized, leading to a significant pressure drop (choose section valve tubes and hose tails of correct size).

How to fix inaccurate adjustment with significant pressure changes on ARAG Farm Equipment?
- L
  Leah BaileyAug 28, 2025
  Inaccurate adjustment with minor switch movements causing significant pressure changes can be caused by a proportional valve not correctly sized for the system (change the proportional valve), insufficient liquid delivery to the control unit (check pump rate and increase pump RPM), or open branches or drain outlets upstream of the control unit.

What to do if sections are issuing product when the discharge valve is open on ARAG 463 Farm Equipment?
- C
  Cory WestAug 31, 2025
  If product issues from the section valves when the discharge valve is open, the discharge valve pipe may be blocked (clean drain passage), equipped with a hydraulic agitator (remove hydraulic agitator and leave hole open), or too small (change drain tube). Also, the discharge valve plug gasket may be worn (bring complete unit to the nearest Service Centre for gasket replacement) or there may be chemical product residue on the gaskets and the discharge valve hose tail fitting (clean parts with suitable detergent as indicated in cap. 6 - Maintenance / diagnostics / repairs).

Why are one or more sections not closing correctly on ARAG 463 Farm Equipment?
- K
  Kristy LopezSep 3, 2025
  If one or more sections are not closing correctly, the section valve motor may not be working (check electric connection), the section valve plug gasket may be worn out (change worn gaskets), or there may be chemical residue on the gasket and seat of the section valve hose tail (clean parts with suitable detergent as indicated in cap. 6 - Maintenance / diagnostics / repairs). If the motor is faulty, have the gearmotor inspected at the nearest Service Centre.

How to handle large pressure fluctuations when closing sections on ARAG 463?
- B
  Brian ElliottSep 7, 2025
  If you're experiencing large pressure fluctuations when one or two sections are closed, the metered by-passes may not be adjusted. Make sure to adjust the metered by-passes.

What to do if the operating pressure is not reached when the main valve is opened in my ARAG Control Unit?
- B
  bryan13Sep 10, 2025
  If the operating pressure isn't reached when you open the main valve on your ARAG Control Unit, several factors could be at play. First, ensure that the intakes and outlets are correctly connected. Next, check the maximum pressure valve to make sure it isn't completely unscrewed; adjust it as necessary. Also, verify that the self-cleaning filter is properly closed. A clogged delivery or suction filter can also cause this issue, so clean the respective cartridges. Finally, ensure sufficient liquid is entering the control unit by checking the pump flow rate, increasing pump revs, and confirming there are no open offsets or discharges before the unit.
