No, the opposite. Gearing down below 7 fps or so doesn't add any pushing power to your drivetrain, as you're traction limited. Basically, if you push with more than a certain force, your wheels will slip no matter what. If you're pushing with 6 CIMs at 5 fps, your wheels will likely slip, and your main breaker will likely be OK (for a while, at least). On the other hand, if you're pushing in an 18 fps gear, your wheels won't slip, your motors will stall, and you will likely trip your main breaker quite quickly.
