Case IH International 674 Tractor Operator's Manual

What's Covered in This Manual

This is the Operator's Manual for the Case International 674 tractor (part number 1084163R3, a factory reprint), written to cover the tractor as it left the factory: with either the IH C-200 gasoline engine or the IH D-239 diesel engine bolted in. Both engine sections are included in full, so whichever engine your 674 carries, the starting, fuel system and daily-operation procedures for it are here.

Beyond the two engine chapters, the manual walks through day-to-day running and routine upkeep: driving and braking, the synchromesh transmission and differential lock, the three-point hitch with draft control, the independent power take-off, auxiliary hydraulic valves, cooling and air cleaning, the electrical system, wheel adjustments and tire inflation, and a full lubrication chart, plus cold-weather and storage instructions.

When ordering parts, record both the gasoline and diesel engine serial numbers from the plate inside the front cover, as this manual explains.
