Case IH CUB Tractor Parts

CUB parts and accessories

The Case IH Cub tractor, manufactured from 1977 through 1979, was a compact utility tractor known for its reliability and versatility on smaller farms. Powered by an International Harvester 6.5L 4-cylinder diesel engine producing around 17 PTO horsepower, it was perfect for tasks like mowing, light tillage, and loader work. Farmers appreciated its simplicity and fuel efficiency, making it a staple in many operations.

The Case IH Cub succeeded the International Harvester Cub, continuing the legacy of a compact and capable utility tractor. Production ran from 1977 to 1979. This model featured an International Harvester 6.5L 4-cylinder diesel engine. While often perceived as a garden tractor due to its size, the CUB was actually classified as an AG tractor. This engine produced approximately 17 PTO horsepower. The tractor typically came equipped with a gear-type transmission offering several forward and reverse speeds, enabling operators to handle a variety of tasks. The 540 RPM PTO made it suitable for operating implements like rotary cutters, tillers, and small balers. Hydraulic capacity was sufficient for operating a basic 3-point hitch system, rated as a Category 0, allowing for the attachment of implements. The Cub was often used in hay production, light tillage operations, and general farm maintenance, standing out from larger Case IH models due to its compact size and maneuverability.

Regularly check and maintain the hydraulic system, including fluid levels and filter condition. Replace hydraulic filters according to the manufacturer's recommendations to prevent contamination.
Inspect the fuel system for leaks or damage. Clean or replace fuel filters periodically to ensure a clean fuel supply and prevent engine problems.
