If you can get a manual, that would be more help than I can probably give, but here's what I remember from a set of those we had about 40 years ago... If the front gangs are "steerable" the connection for the steering is made to the front bolster shaft. The insert in the lower part of the grill comes out, and a yoke is bolted to the bolster shaft with a key in it to keep it from rotating on the shaft. That's one of the last steps in the setup. I'm guessing that your front gangs are all attached together with angle iron that runs full length across the front of the tractor. If not, then it's a different type from what I'm describing. There should be two plate brackets about 16" long by 4" wide with a right-angle bend on the end featuring a "pin" about an inch long and a notch on the top of the short part of the angle. The plates mount on the sides of the fram rails and front bolster. On an H, turn the angles OUT with the notches on top. On an M, turn the angles IN and still with the notches on top. The pins line up with a hole in front angle iron of the cultivators, and the angle iron slips into the notches. Once you have it attached this way, the cylinders and lift arms go back to the rear axle brackets on each side. For the rear gang, remove the drawbar, and use the same bolts to hold the cultivators to the axle. The hydraulic cylinders are connected to the three ports on the side of the transmission housing where the hydraulic pump is. Front gang cylinders connect to the right side port and the front port on the left side. Rear gang cylinder connects to the rear port on the left side. Most of these old Farmalls have a delayed lift setup in the hydraulic pump. This will allow you to lift the front gangs and by holding the lift lever up, raise the rear gang at about the same place when in third of fourth gear. The front gangs may be dropped independently (and before) the rear gang. Good luck!
