| Not true. I know that's an argument the CIH guys use to promote the QuadTrac, but it's not quite that simple. The error comes in that the Cats use differential steering, which is far more advanced and smooth than the clutch type steering used on Cats and other track vehicles decades ago. The clutch-steered units would do that-cut power to one side and while the other alone had power. In differential steering, the nut behind the steering wheel controls how aggressively the tractor turns or attempts to turn. You can make turns while still applying power to both sides and, as the name would imply, through differential action you are reducing the speed (not torque) of one side while increasing it in the same ratio on the opposite side. If you make aggressive steering actions, sure, it will sit and spin on one side, but that is up to the operator. | |
