Overview
Manufacturer
International HarvesterReference
International HarvesterReference
The Agriomatic S provides an additional four forward speeds selected by a right-hand power shift lever. Pushing the lever forward engages the Agriomatic range, while rearward uses the conventional range. The Agriomatic speeds are between high and low ranges, so this provides an undershift in high range and an overshift in low range. In reverse range it operates as a power shuttle.Reference
