John Deere 9770

The Challenge

The machine was underpowered for the job; it was dropping 300rpm when working hard in the crops. The resuting product was not clean as the hydraulics where not keeping up.

The Solution

Our dealer read out the factory ECU data via a special tool and advised us on the machines engine specifications, the work it was doing and the local enviromental conditions. We then modified many key parameters such as injection, the torque limiter and EGR system function. After the tune was loaded, the 9770 was tested and was not dropping any rpm under load. Ground speed was up by 6% and fuel usage was improved by 5%.
