First gear will be in the 6.5:1 range, give or take a few points; second will be around 3.0 or 2.5, third in the 1.7 range, and fourth is 1:1. Basically, it is a three speed, with a very deep additional first gear for getting heavy loads started, and creeping and crawling in rough terrain. The side plates are for the PTO takeoffs; if I remember right, one will run off of the cluster gear, and the other is driven from the output shaft; they have different applications.
