1967–1969 International Cub Cadet 72/104/105/124/125 Tractor Operator's Manual (P/N 1 082 659 R2)

International Harvester's operator's manual covers the 1967–1969 International Cub Cadet 72, 104, 105, 124 and 125 tractors. The January 1969 issue bears document code 1 082 659 R2, Rev. 3 and covers operation, maintenance and lubrication.

Partial Text Search, Cover Bookmarks and PDF Contents

Search and diagram detail: Existing OCR supports text search on some pages, but the wiring diagrams, printed contents/index and specification tables lack searchable text. Two embedded bookmarks open the added cover and original manual cover; they do not provide chapter navigation. Small wiring labels are readable with zooming.

Supplied as one printable, 45-page PDF: the 44-page manual, including its original covers and two memoranda pages, plus one added cover page. All are included in the total.

Fuel, Drive Controls and Routine Tractor Maintenance

Beyond these selected topics, the manual also covers seat positioning and hood access.

• Fuel and ignition: Carburetor high-speed and idle adjustments, fuel-strainer and sediment-bowl cleaning, ignition timing, breaker-point adjustment and spark-plug care.

• Clutch, brakes and hydrostatic control: Gear-drive pedal adjustments, hydrostatic brake settings and external speed-control linkage adjustment for creeping in neutral.

• Electrical system: Lighting and electric-starting wiring diagrams, cable identification, battery maintenance, motor-generator belt replacement and lighting fault checks.

• PTO and implement controls: Rear PTO operation, front PTO button-clearance adjustment, drive-belt removal and installation, implement lift settings and hydraulic-unit operation.

• Steering and tires: Front-wheel toe-in and turning-radius adjustments, Terra-Tire applications, tire mounting and inflation tables for normal and heavy loads.

• Lubrication and troubleshooting: Separate gear-drive and hydrostatic lubrication guides, transmission-filter replacement, symptom tables, seasonal storage and return-to-service procedures.

Written for tractor owners and operators, this manual explains everyday operation and routine maintenance, with referrals to dealer service for more involved repair work.

Kohler Engines, Fuel and Ignition

Engine specifications separate the Model 72's Kohler K161S electric-start and K161T manual-start configurations from the K241AS used in the 104/105 and K301AS in the 124/125. Bore, stroke, displacement and cold valve-clearance data distinguish the engines, including the Model 72's different valve settings.

Carburetor illustrations locate the mixture controls, while the timing-sight-hole illustration distinguishes the Model 72's access point from the other tractors. Step-by-step instructions describe carburetor adjustment and timing-light use.

The cooling and dry-type air-cleaner sections cover cleaning and element replacement. Compressed-air cleaning can rupture the paper filter element, a specific caution explained in the air-cleaner instructions.

Troubleshooting tables link hard starting, irregular running, knocking, low power and overheating to possible causes and maintenance references. This helps distinguish basic fuel or ignition checks from faults referred for engine repair.

Gear Drive, Hydrostatic Control and PTO

The driving instructions distinguish gear selection on the 72/104/124 from hydrostatic speed control on the 105/125, including rotary-tiller operation. The optional creeper drive and rear PTO apply to the gear-drive tractors.

Clutch and Brake Adjustments (Illust. 24) identifies the pedal's clutching, neutral and braking zones. The hydrostatic linkage procedure addresses creeping after the brake has been correctly adjusted.

Internal hydrostatic repair is referred to the dealer. This operator's manual does not provide engine or transmission overhaul procedures. Front PTO coverage includes button-clearance adjustment and belt work; slipping clutches requiring special equipment and instructions are also referred for dealer service.

Hydraulic Lift, Hitching and Lubrication

Drawbar and three-point-hitch coverage explains implement positioning and lift-handle float settings. The hydraulic-unit section describes the self-contained gear pump, directional control valve, reservoir and cylinder, with operating, filling and leak-check instructions.

The separate Lubrication Views (Illusts. 31 and 33) locate service points for each drivetrain type. Related schedules and the lubrication table specify IH Hy-Tran applications, steering-gear lubrication and hydrostatic transmission oil-filter replacement.

Tire information distinguishes normal from heavy-load pressures and standard from optional Terra-Tire applications. Rear wheel weights and tire chains are also covered.

Electrical Diagrams and Service Precautions

The Electric Lighting Wiring Diagram (Illust. 21) and Electric Starting Wiring Diagram (Illust. 21A) identify circuits through numbered cable references. The starting-circuit index supplies wire colors and terminal designations for tracing electrical connections.

The motor-generator belt section warns that using a pry bar for belt tension can damage the bearings. Observe the manual's PTO guarding and battery-isolation precautions during service.

A Preview of Steering and Clutch Adjustment Data

Front-wheel alignment coverage specifies 1/32–1/8 inch of toe-in, measured at the inside wheel edges at hub height, with the front measurement smaller than the rear.

For the 72/104/124, clutch adjustment data specifies 0.050 inch between the release lever and release bearing. The corresponding pedal free movement is approximately 3/16 inch, measured where the pedal arm contacts the front edge of the pedal return stop.
