Challengers going back | The Farming Forum Similar situation. Emission issues?Don't think they are out yet, the ones we have on order that were supposed to be delivered to the dealership in September have moved to 1Q 2015. Haven't heard why but will update when I know more.
The engines have had to be modified to go in the tracked Challengers, they have been shaking themselves to pieces so they are not the same engines.The same engine is in the two combines, they are marked final tier IV, why wouldn't they meet it in the tractor?
The only thing Cat on the E Series is the transmission. I don't believe there is anything coming out of Jackson now with a Cat engine. From the fuel consumption and torque difference I have seen between the Sisu and Cat engines I just can't imagine why anyone would want the Cat engine.
