| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Internal Combustion Engine (internal_combustion_engine) | required | 84% | expert_inference | The scoped 1892 tractor was a gasoline-engine tractor, so internal combustion is a core component dependency. |
|
| Plow (plow) | historical_predecessor | 62% | expert_inference | Plowing was a primary farm-power application for tractors, but tractors also hauled and powered other equipment. |
