ENGINE DETAIL
The Farmall 1206 features a robust International Harvester DT361 turbocharged diesel engine with a displacement of 5.9L, providing substantial power for demanding agricultural tasks. Its 17.0:1 compression ratio enhances fuel efficiency and torque delivery, making it suitable for heavy implements and field work at the rated RPM of 2400, though potential challenges include the need for regular turbo maintenance and monitoring for any related exhaust temperatures. The two-stage dry air cleaner is effective in prolonging engine life by minimizing particulates, but operators should be vigilant in maintaining it for optimal performance.

TRANSMISSIONS OVERVIEW
The Farmall 1206 features an 8-speed unsynchronized transmission with a 16-speed partial power shift, providing flexibility in power management for varied field conditions. Advantages include smoother transitions between gear ratios, enhancing operational efficiency, though the unsynchronized system may require experienced operators to shift effectively under load. This configuration is ideal for tasks requiring both heavy drafting and fine control, such as tillage and planting in diverse terrains.
