Part of the John Deere Repair Manuals.
A clutch that slips halfway through second cut won't wait for a dealer appointment, and neither will you. This John Deere 2950 Technical Manual PDF puts all 844 pages of factory publication TM4407 behind your tractor, from the radiator back to the Roll-Gard structure, covering the 2950 only with no serial-number cutoff in the book. Engine overhaul for the 6-cylinder, 359 cu in diesel is in JD's separate CTM-4 manual; this one stops at the block. Wiring diagrams trace the harness through the starting motor and alternator, hydraulic schematics map the pump and selective control valve, and power train coverage runs from the Hi-Lo shift unit to the differential. Fill the cooling system to 17 L (4.5 US gal) without Sound-Gard body, and torque the front axle carrier to engine block cap screws to 230 N·m (170 ft-lbs). Every procedure carries factory torque values and clearances, not a guess. Bookmarked and text-searchable, the PDF goes wherever the tractor is parked.
