Good question. The belly pump works when the clutch is out. It has three output ports. Two on the left side of the tractor, and one on the right. These ports are not all the same. The front port on the left side (not in your photos) is connected internally to, and is the same pressure at the same time, as the port on the right (shown as connected to the valving christmas tree). The Christmas tree is an accessory to the tractor. The rear port on the left side is a delayed action port. This port(with a one way restrictor hose fitting in the line) is hooked to implements that are lifted in a sequence at the end of a row and put back in the ground in sequence (front first then rear) I would ignore it. The control lever (wired back) has four positions: All the way out (as it is wired now)=lift pressure Rod moved to mechanical stop (you do not have the rod with stop) about 15 degrees clockwise on the wired lever, is hold. Holds pressure lift in the lines going to the out put ports Further in on rod (you do not have) to an internal detent= lower Full in to end of travel (full CW on wired lever)= Full down. The pump is one way, (when all the accessory valving is removed, and the three ports are all there is). The fluid moves out the hoses, and returns through the same hoses. With the Christmas tree, two way action is allowed, and the return is in the T at the top of the filler. JimN
