One thing that I never quite understood from the first I noticed it probably 30 years ago with the Victas is why they turned the motor sideways. There probably was a reason for it,but the first time I played with one of these east/west motors, the sideways vibration was increased and this in turn caused extra wear on the wheel bushes. With the north/south configuration the wheels take a lot of this vibration out of it because they can move back and forth, not bash sideways all the time
