    What to do if Gehl RT175 Compact Loader engine runs, but travel drive doesn't operate?
    • E
      ehernandezAug 8, 2025
      If your Gehl Compact Loader's travel drive isn't working despite the engine running, several things could be the cause. The parking brake might be applied, so disengage it. There could be a parking brake switch malfunction, so replace the parking brake switch(es). A blown fuse could also be the issue, so check the circuit and replace the fuse. The operator might not be in the operator’s seat, so ensure the seat is occupied for the travel drive to operate. The cab door might be open (if equipped), so close the cab door. A drive system component malfunction could also be the problem or there might be an error code present.

    Why aren't the hydraulics working on my Gehl RT175 Compact Loader?
    • J
      Jennifer DavisAug 12, 2025
      If the hydraulics on your Gehl Compact Loader aren't working or have poor performance, there are several potential causes. There might be an error code present. The hydraulic oil level could be low, so top it off. The hydraulic oil might not be at operating temperature, so allow for a longer warm-up. Other possibilities include damage to the engine to pump coupling or hydraulic pump (contact dealer), pressure limiting valves set too low or damaged (contact dealer), damaged hydraulic cylinder(s) (contact dealer), damaged control valve(s) (contact dealer), engine speed too low (adjust engine speed), or dirty/restricted air filter(s) (replace filter(s) and/or remove restriction).

    How to troubleshoot loss of electrical power in Gehl RT175?
    • T
      Tiffany DavisAug 17, 2025
      If you're experiencing a loss of electrical power in your Gehl Compact Loader, start by checking the battery terminals and cables for looseness or corrosion; clean and tighten them as needed. If that's not the issue, the battery itself might be malfunctioning, so test it and recharge or replace it as necessary. Finally, a blown main fuse could be the culprit; correct the over-current problem and replace the main fuse.

    What causes instrument display not to activate on Gehl RT175 Compact Loader?
    • G
      Gregory SanchezAug 21, 2025
      If the instrument display on your Gehl Compact Loader doesn't activate when the ignition is turned on, it could be due to a few reasons. First, check for a blown main fuse and replace it after correcting any over-current issues. Also, inspect the battery terminals and cables for looseness or corrosion, cleaning and tightening them as needed. Another possibility is an ignition switch malfunction, which would require replacing the switch. In very cold weather, the display screen might be slow to activate, so allow a few minutes for it to display.

    Why won't my Gehl Compact Loader engine start?
    • Y
      Yvonne TaylorOct 26, 2025
      The Gehl Compact Loader might not start due to several reasons. It could be an error code “0” because the arm rest/safety bar is in a raised position, the cab door isn't closed (if equipped), or the operator’s seat isn't occupied. In this case, lower the arm rests/safety bars, close the cab door (if equipped), and occupy the operator’s seat. Alternatively, it might be an engine error code “1078-4”, in which case you should check the starting circuit wiring. Other potential causes include a blown fuse (check the circuit and replace the fuse), a dead battery (charge or replace the battery), a malfunctioning seat switch or safety bar arm/rest switch (replace the switch), a starter malfunction or engine electronics logic error (contact dealer), or the multi-purpose display not completely initi...

    What to do if Gehl Compact Loader engine turns over but doesn't start?
    • D
      Debra EsparzaOct 30, 2025
      If the engine of your Gehl Compact Loader turns over but doesn't start, several factors could be at play. The engine cranking speed might be too slow, so check the battery and charge or replace it if necessary. The fuel tank could be empty, so fill the tank and vent the fuel system. A plugged or restricted fuel filter could also be the culprit, requiring a replacement. In winter, paraffin separation might occur, so use winter grade diesel fuel. Check for fuel line leakage and tighten all threaded connections and clamps. Other potential issues include a pre-heating module malfunction (check connection and voltage and charge/replace as necessary), the fuel shut-off solenoid not energizing (check electrical connections/voltage to shut-off solenoid), a fuel pump malfunction (contact dealer), t...

    Why is my Gehl RT175 Compact Loader engine overheating?
    • R
      Randall AlexanderNov 2, 2025
      If your Gehl Compact Loader's engine is overheating, there are several potential causes. It could be due to an incorrect engine oil level (adjust the oil level), restricted cooling air circulation (turn the engine off and allow it to cool, then remove the restriction), or an improperly positioned fan shroud (contact dealer). Other possible reasons include using an improper oil grade or excessively dirty oil (change the engine oil and filter), a restricted exhaust (turn the engine off and allow it to cool, then remove the restriction), a restricted air filter (replace the filter(s)), a low coolant level (add coolant), leaks in the coolant system (repair/replace if necessary), a loose/worn V-belt (tighten/replace the V-belt), a dirty/restricted radiator (clean the radiator), or a slipping fa...
