As they stick up in the air, the leftmost lever is for the PTO winch, and the lever being painted to its right (which bends around the parking brake) is the shifter for the 4 speed transmission. Next is the parking brake and on the other side of the transmission the lever to the left operates the High/Low transfer case which, when combined with the the 4 speed transmission, gave you 8 speeds forward and two in reverse. The last lever on the far right is to engage the front wheel drive.
