| Looking online at used Challenger 45 with Caterpillar 6.6L diesel and 55 with Caterpillar 7.2L 6-cyl diesel. Is fuel system still mechanical or electronic injection? Are these good engines? One better than the other? Behind motor is what appears to be NH Genesis for cab and drive train. Is the track system is tension only, no cogs in belts? What are pros and cons of these Challengers? How would they be on grain cart? | |
