Gehl 4625 Common Problems This Manual Covers
Hydraulic leak near the tandem pump
Owners report hydraulic fluid leaking around the tandem pump to engine adapter area and under the cab. A failed seal at the pump-to-adapter interface or related seal wear is the typical source.
Manual Section: Hydrostatic System p. 145No-start or intermittent cranking
The machine will not start even with a fresh battery. Weak cables or grounds, a failing starter or solenoid, or a lap bar safety switch fault are the common causes.
Manual Section: Electrical System p. 235Lift or tilt functions weak
The lift or tilt is slow, weak, or drifts. Worn cylinders, a control valve relief pressure that is off, or a self-leveling valve fault should be tested against the hydraulic troubleshooting guide.
Manual Section: Hydraulic System p. 177Drive chain stretched or noisy
Slack or noisy drive chains cause uneven tracking and drivetrain wear. The Drive section covers chain deflection checks, adjustment, and axle and sprocket service.
Manual Section: Drive p. 62Damaged wiring causes electrical faults
Chewed or degraded insulation and corroded connections lead to electrical faults and starting problems. Pin voltage and pin measurement procedures help isolate the damaged circuit.
Manual Section: Electrical System p. 235Engine hard to start or runs rough
The Kubota V2203B can be hard to start or run poorly, often from restricted fuel or air filters or air in the fuel system. The Engine section covers filter service and troubleshooting.
Manual Section: Engine p. 251Frequently Asked Questions
