John Deere 240 and 250 Skid Steer Loader Technical Manual TM1747

What's Covered in This Manual

This is the official John Deere TM1747 Technical Manual for the 240 and 250 Skid Steer Loaders, published by the Worldwide Construction and Forestry Division in February 2003. This manual is written for an experienced technician and is part of John Deere's total product support program for this compact skid steer lineup.

Inside, the manual covers the chassis, hydraulic system, electrical system, and drive components shared across both models, with diagnostic charts that walk a technician through common complaints like a leaking water pump or a charging system fault before any teardown begins. For engine-specific repair work, the manual directs the technician to a separate companion component manual, CTM125, and for starter and alternator service it references CTM77 - both cross-referenced directly within the diagnostic procedures in this manual.

Both model numbers, the 240 and 250, are confirmed present throughout the manual text. Whether you're troubleshooting a hydraulic or electrical fault, doing routine maintenance, or working through a driveline repair on either model, this manual provides the complete factory-level procedures and specifications a John Deere technician would use.

The diagnostic charts throughout this manual are written to walk a shop through a logical check sequence - confirming the simple things first, like a leaking seal or a loose belt, before moving into a deeper hydraulic or electrical investigation. That approach saves real labor time compared to pulling a pump or a harness on a guess, and it's especially useful for a shop that doesn't service John Deere skid steers every day and wants a reliable, repeatable troubleshooting process to follow.
