The tractor pull challenge is a test of strength instead of speed. The test is to see which robot can pull the most weight 50cm in the least amount of time. To do this we will need to reverse the gears on our robot due to the fact that right now they are set up for speed, not strength. To get the proper gear ratio for strength, our robot needs a larger driven gear (the one connected to the wheel) than the driving gear. This will cause the robot to move at a steady rate, but be able to pull a lot of weight.
