From the sound of things, I'd bet you had two problems: your gear ratio was too high, and the treads on your wheels were too grippy. Those two things together can cause big problems for any robot. However, if you pick the right tires and the right gear ratios, 4WD can be many times better than 2WD for pushing power, especially.
