Common Engines:
Likely features Kohler single and twin-cylinder engines (e.g., K-series) and potentially Onan engines, depending on the specific model and year within the 72, 104, 105, 124, 125 range. Displacement typically 8 to 16 HP.
Typical Horsepower:
Ranges from approximately 7 HP (Model 72) to 12 HP or more (Models 104, 105, 124, 125).
Fuel Delivery:
Carbureted, typically with a fuel pump and sediment bowl/filter. Manual covers carburetor adjustment, cleaning, and rebuilding.
Transmission Types:
Both manual (gear drive) and hydrostatic (variable speed) transmissions were offered across these models. The manual covers the specifics of each type.
Transmission Options:
Hydrostatic drive was a significant option, offering smoother speed control. Manual transmission models typically had 3-6 forward speeds plus reverse.
Drivetrain Features:
Features include differential lock (on some models), rear PTO shaft for attachments, and robust axle systems.
Engine Oil Change:
Typically every 25-50 operating hours or annually. Consult the manual for precise intervals based on engine model and operating conditions.
Engine Oil:
SAE 30W or 10W-30 (depending on climate and engine manufacturer recommendations). Manual will specify exact grades and API service classifications.
Hydraulic Oil:
IH Hy-Trans fluid or equivalent UTF (Universal Tractor Transmission) fluid. Capacity varies by model. Manual will provide specific part numbers or specifications.
Gear Oil:
Typically SAE 80W-90 or 85W-140 gear oil for the transaxle/differential. Manual will confirm type and capacity.
Common Wear Points:
Wear in steering components, hydraulic lift cylinders and pumps, transmission gears, and PTO clutch wear are common, all addressed in the manual.
Electrical Reliability:
Wiring harness degradation, starter solenoid issues, and charging system (generator/alternator) maintenance are frequent topics covered for longevity.
Oil Filter:
Manual will list specific IH or equivalent part numbers (e.g., for Kohler engines). Examples might include filters like Fram PH2, Wix 51049, or IH equivalent numbers.
Fuel Filter:
Manual will specify IH or aftermarket fuel filter part numbers, often a small inline filter.
Manufacturer:
International Harvester (IH) was a legendary American manufacturer known for its agricultural machinery and durable vehicles.
Cub Cadet Line:
The Cub Cadet line, introduced in the early 1960s, represented IH's entry into the consumer lawn and garden tractor market, building on the legacy of the Farmall Cub. These models represent a core generation of that line.
Production Period:
Models 72, 104, 105, 124, 125 were primarily produced in the mid to late 1960s (circa 1965-1969).
