Issued at the factory as Form No. 50940159, this 218-page Gehl RT175, RT210, RT250 operator manual PDF is the factory book for all three compact track loaders, running from the delivery checklists to the torque tables at the back. Electrical schematics fill a solid block of the book, drawn separately for the RT175/RT210 and the RT250, and trace the engine ECU, power distribution, solenoid controllers and the Power-A-Tach quick-attach circuit, with a full hydraulic schematic after them. Troubleshooting runs from engine and hydrostatic travel drive faults through controller, engine, drive and valve error codes, so a warning on the multi-function display leads you to a cause, while the maintenance chapter sets out every interval and filter change. Fill the RT175 hydraulic tank to 41.6 L (11 gal.); the RT210 and RT250 take 52.2 L (13.8 gal.). Limp mode with an unexplained code eats a shift. The PDF is bookmarked and text-searchable, and it stays on your phone or laptop, so the book is wherever your loader is parked.

Gehl RT175, RT210, RT250 Common Problems This Manual Covers
Gehl RT175, RT210, RT250 compact track loader hydraulic oil temperature indicator lamp lights up during heavy work
Check the hydraulic oil level in the tank first. The fluids table on page 37 lists tank capacity for your model. Inspect the hydraulic oil filter indicator on the multi-function display, then work through the Indicator Lamp Troubleshooting chart. Clean the engine radiator per the cleaning items in the maintenance schedule on page 106.
Manual Section: Indicator Lamp TroubleshootingEngine overheating and coolant temperature indicator lamp lit on the multi-function display mid-shift
Check coolant level only after the engine cools, and compare the mix against the Coolant Compound Table in the specifications starting on page 31. Verify the radiator cap carries the correct 0.90 bar (13 psi) rating listed on page 37. Clean the engine radiator, then recheck the lamp at idle before going back to work.
Manual Section: Engine TroubleshootingEngine runs normally but hydrostatic travel drive does not operate in either direction
Verify the parking brake is released and the drive controls respond, then open the Maintenance and Error Code screen on the multi-function display. Record any active code and match it against the Drive and Valve Error Codes table. Check the hydraulic oil level in the tank before you call for service.
Manual Section: Hydrostatic Travel Drive System TroubleshootingController communication error code showing on the multi-function display right after key-on startup
Open the Maintenance and Error Code screen and write down the exact code before you cycle the key. Match it against the controller communication error tables starting on page 153. Check the battery voltage indicator and work through the Electrical Troubleshooting chart before replacing any controller.
Manual Section: Error Codes p. 153Straight pipe hydraulic fitting with sealing washer leaking fluid at the connection
Clean the fitting dry, then run the machine briefly and watch where fluid first appears. Check the thread size and tighten to the value in the hydraulic fittings table on page 215; an M16X1.5 straight fitting with sealing washer takes 45 Nm (33 lb.-ft.). Replace the sealing washer if weeping continues.
Manual Section: Seal and Hose TroubleshootingStarter does not engage and instrument display stays dark when the key is turned
Check battery voltage first, and confirm the battery meets the cold cranking amp rating for your model on page 46. Work through the Electrical Troubleshooting chart for loss of electrical power before you condemn the starter. Recharge or replace a battery that will not hold voltage.
Manual Section: Electrical TroubleshootingFrequently Asked Questions
What causes Gehl RT175 pump left/right sensor neutral drift faults?
Pump sensor neutral drift faults (Error codes 1 and 2) are identified as drive and valve system errors. These faults indicate an issue with the pump sensor calibration or signal, and the corrective action is to contact your dealer for service. p. 173
How do I troubleshoot Gehl RT210 drive and hydraulic error codes?
Drive and valve system errors are listed in Table 53 on page 173. If an error code is displayed, you should identify the specific code and follow the corresponding description, which often requires contacting a dealer for technical assistance. p. 173
What are the engine oil and filter replacement specs for the Gehl RT175, RT210, RT250?
The engine oil and filter should be changed after the first 50 hours of use, and every 250 hours thereafter. The oil capacity for the RT175 is 10.4 L (11 qts.) and for the RT250 is 8.5 L (9 qts.). p. 107
What is the procedure for checking and adjusting the V-belt tension on the RT175?
Check the V-belt condition monthly or after every 100 hours of use. Press on the V-belt mid-way between pulleys; it should not deflect more than 8 mm (5/16"). If it deflects more, loosen the adjustment bolt and rotate the alternator outward until tension is correct. p. 115
What is the hydraulic oil tank capacity for the Gehl RT250?
The hydraulic oil tank capacity for the Gehl RT250 is 52.2 L (13.8 gal.). p. 37
