John Deere 2955 3055 3155 3255 Tractors Repair Technical Manual TM4449

What's Covered in This Manual

This is the official John Deere TM4449 Technical Manual for the 2955, 3055, 3155, and 3255 Tractors, published in December 1991. This closely related family of four tractors shares a common platform, and this single manual covers the full repair procedures across all four models, with all four model numbers confirmed present throughout the manual text.

Inside you'll find complete repair coverage for the engine, power train, hydraulics, electrical system, and steering used across this tractor line, with torque specifications, wear tolerances, and special tool requirements included throughout so a rebuild comes back within factory spec. Because these four models span a range of horsepower and configuration options within the same family, the manual calls out model-specific variations where a repair procedure or specification differs between the smaller 2955/3055 and the larger 3155/3255 tractors.

Whether you're troubleshooting a hydraulic issue, rebuilding a transmission, or doing a full engine overhaul on any tractor in this four-model lineup, this manual provides the same factory-level repair procedures a John Deere technician would use, covering everything from routine maintenance through complete component disassembly and reassembly.

The electrical and power train sections include wiring diagrams and transmission exploded views that make tracing a fault or ordering the correct internal components much easier than working from guesswork, and the hydraulics section covers both the loader and remote implement circuits where equipped. For a shop or owner-operator servicing one of these tractors decades after it rolled off the line, this manual remains the most reliable source for factory torque values and tolerances, since aftermarket references often omit the detail needed for a repair that will actually hold up under field use.
