All 108 pages of this Case IH 300 Operator Manual (OEM #1004400R4) are factory-written for one machine: the International 300 Utility Tractor. Inside: complete operating procedures for the Hydra-Touch hydraulic system, Fast-Hitch, Torque Amplifier, and independent PTO, plus a full lubrication guide covering every grease point and oil specification on the tractor. You also get wiring diagrams for the battery ignition and starting circuits, a troubleshooting section, valve clearance adjustment procedures, and a full accessories chapter covering hydraulic power steering, wheel weights, and lighting options. Set breaker point clearance to .020 inch, then confirm the Torque Amplifier clutch release bearing holds 3/16 inch of clearance from the release levers. Your 300 is sitting idle. Get the factory number on the first try, not the third phone call to a dealer. Bookmarked by section; pull it up on your tablet and walk straight to the machine.

Case IH 300, 300 Utility, International 300 Utility Common Problems This Manual Covers
Case IH 300 tractor cranks but won't fire, or starts then immediately dies
Check for fuel at the carburetor by opening the petcock and inspecting the strainer bowl for debris. Pull a spark plug and ground it against the block; weak or no spark points to the ignition. Inspect the magneto breaker points and reset the gap to exactly .020 inch (page 46). Work through the no-start diagnostic sequence starting before going further.
Manual Section: Ignition and Electrical System FaultsPTO shaft stays engaged and spins continuously, won't disengage when lever is released p. 67
Inspect the PTO engagement linkage for a bent rod or disconnected clevis at the lever pivot. On 300 Utility Tractor models equipped with the Torque Amplifier, verify the clutch release bearing clearance is exactly 3/16 inch between the bearing face and the release levers (page 67). Refer to the Independent Power Take-Off section for band adjustment steps before attaching any implement.
Manual Section: Independent Power Take-OffEngine temperature climbing steadily during field work, steam venting from radiator overflow
Check coolant level daily before startup; a low system overheats quickly under load. Inspect the radiator core for packed chaff or mud and clear it with compressed air before entering the field. Verify the fan belt is not cracked, glazed, or slipping on the pulley. If the temperature stays high after correcting these items, work through the cooling system fault sequence starting.
Manual Section: Cooling System OverheatingHydra-Touch system won't raise the implement, lifts unevenly or not at all
Verify hydraulic oil is at the correct level before each day's work; low fluid causes erratic or absent lift response. Check that the Hydra-Touch control lever moves freely through its full range without binding or sticking. Inspect line connections for leaks at the implement attachment points. Work through the Hydra-Touch fault sequence starting for pump laboring and unsteady pressure conditions.
Manual Section: Hydra-Touch System FailuresClutch slips under load or tractor won't hold gear on inclines
Inspect the clutch lining for grease or oil contamination; even light contamination causes slipping immediately under load. Check clutch pedal free travel daily and adjust linkage if the pedal engages at the very top or bottom of its stroke. Clean any contaminated lining surfaces before returning to heavy drawbar work. See the troubleshooting sequence starting for dragging and slip conditions.
