    What to do if the venturi is filling up with product and spilling over on my Valmar 2055?
    • D
      Dr. Justin Crawford DDSAug 16, 2025
      If the venturi is filling up with product and spilling over in your Valmar Farm Equipment, consider these potential causes. The fan inlet might be plugged, so unplug it. The fan speed could be too low; increase the fan speed to 17 inches water column pressure. Inspect the fan to manifold hose for tears or operational issues; replace the hose if necessary. Ensure the fan is operating and engage the fan drive if it isn't. The manifold pressure gauge might be giving an inaccurate reading, so replace it. The manifold could be plugged; clean it out. The product might be caking up in the venturi; clean the venturi. Also, clean out the hopper if there is water in it and run the fan to blow-dry the delivery system if there is water in the manifold.

    Why is product shooting out of the venturi of my Valmar Farm Equipment?
    • J
      James BrooksAug 20, 2025
      If product is shooting out of the venturi due to back pressure in your Valmar Farm Equipment, it could be due to a few reasons. Check for obstructions in the delivery hoses and unplug them if necessary. A collapsed delivery hose could also be the culprit, so replace the hose if it is. The fan speed might be too low, so increase it to 17 inches water column pressure. Finally, your field speed might be too fast, causing the product to be metered into the venturis faster than the airflow can carry it, so slow down.

    What to do if the clutches will not engage on my Valmar 2055?
    • J
      Justin WhiteAug 25, 2025
      If the clutches on your Valmar Farm Equipment will not engage, start by checking the power cable to the battery, fuses, wiring harness, and all connections to ensure there is electrical power to the clutches. If there is dirt lodged between the clutch halves, pull the clutch halves apart, clean the contact surfaces, and reset to the proper gap. Finally, if the gap between the clutch halves is too wide (should be 1/32”), disassemble the clutch and remove the spacer ring.

    How to stop static electricity from making product cling to the venturi in my Valmar 2055 Farm Equipment?
    • M
      mike58Aug 27, 2025
      If product clings to the venturi due to static electricity in your Valmar Farm Equipment, it's likely because an electrical charge is building up in the venturi. Clear the venturi by pushing the product through with the fan running. Wipe the venturi with an antistatic towel. If the problem persists, ground the venturi to the manifold by running a small wire, preferably copper, through the venturi cup and into the manifold, ensuring the wire contacts the manifold.

    Why is the speed fan too slow on my Valmar 2055?
    • G
      Gary FlowersAug 31, 2025
      If the speed fan is too slow on your Valmar Farm Equipment, first check if the fan drive belt is loose and adjust the tension if needed. Next, ensure the flow control valve is properly set. Finally, verify that the tractor is providing sufficient oil supply by checking the hydraulic oil flow specifications for the tractor and ensuring that the tractor hydraulic system is working properly.

    What causes hydraulic motor leaks in Valmar 2055?
    • M
      Mary BurkeSep 4, 2025
      If your Valmar Farm Equipment's hydraulic motor is leaking, it could be due to several reasons. The seal might be worn or damaged by heat, or overpressure might have ruptured the seal. Alternatively, contaminants could have damaged the seal. In any of these cases, replace the seal. Also, ensure that the oil supply is clean to prevent future damage from contaminants.

    Why does the hydraulic fan drive surge and/or overheat in my Valmar Farm Equipment?
    • D
      Donna StricklandSep 7, 2025
      If the hydraulic fan drive surges or overheats on your Valmar Farm Equipment, it might be because the Valmar flow controller is incompatible with your tractor’s hydraulics. In this case, install a Valmar flow control bypass kit.

    Why is the application rate lower than expected on my Valmar 2055?
    • C
      Christopher SmithNov 11, 2025
      If the rate of product being applied by your Valmar Farm Equipment is lower than expected, several factors could be at play. First, the product density may have changed, causing a discrepancy with the applicator charts; in this case, you should calibrate your applicator and create a new chart. A mathematical error could have occurred during calibration, so recheck your calculations. Also, verify that you accurately weighed the calibration sample. Furthermore, the actual acreage covered may be less than expected; recheck the field size, keeping in mind that tractor wheel slippage can cause an incorrect odometer reading. Ensure the gearbox setting is correct and that the sprockets aren't slipping on the shafts. Also, check if the ground drive wheel is slipping or if misaligned shafts and spr...
