Built for Tough Tractor Duty: TICO Tractors Cummins ISB 6.7 L DEF Head Unit
What is it?
The TICO Tractors Cummins ISB 6.7 L DEF Head Unit is an emissions-critical module integrated into the SCR (Selective Catalytic Reduction) system of TICO utility and agricultural tractors running Cummins ISB 6.7 L engines. It meters Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce nitrogen oxide (NOx) emissions. Built-in sensors monitor DEF fluid level, temperature, and pressure in real time to ensure undeniable SCR system precision—even under rugged field conditions.
Why choose the TICO-specific DEF Head Unit?
This OEM-grade DEF head unit is purpose-built for seamless integration with TICO chassis and Cummins engine systems. It installs plug-and-play using factory ECM settings and wiring harnesses. By matching TICO calibration protocols, it eliminates DEF dosing discrepancies, SCR fault codes, and engine derates often caused by off-brand modules. Constructed for durability, it stands up to vibration, dust, and temperature extremes typical in agricultural operations.
