| Same here, there is a significant difference in powertrain efficiency between a Quad-Trac and the Cat. And with fuel prices high, it makes a big difference on the operating cost of these machines going several hundred hours in a season. A good deal of parasitic loss through the articulated frame driveline, 2 drive axles instead of one on a Cat, and 4 sets of undercarriages instead of 2. There is still no more efficient way of getting power to the ground than through the Cat. I think there are definitely sectors that can use the Quad-Trac (construction, etc.) and applications in which it certainly can excel, but with fuel economy becoming increasingly important, many farmers may re-evaluate the QT as their high hp tillage tractor in favor of the more efficient Cats. | |
