The 1026 featured a standard 540 RPM PTO, providing power for a wide range of implements. The hydraulic system delivered around 16 GPM of flow, powering multiple remote valves for implements such as planters and cultivators. The 3-point hitch was typically a Category II hitch, capable of lifting several thousand pounds, depending on the specific configuration. The 1026 found applications in row crop farming, hay production, livestock operations for tasks like baling and feeding, and tillage work. Its higher horsepower set it apart from smaller utility tractors in the IH lineup, while its sturdy build distinguished it from lighter row crop tractors.
