Cultivators

I looked at and bought a set of cultivators for my Farmall H this afternoon. At least they are supposed to be for an H. They looked like more than would easily fit into the back of my truck with the cap on so I have to go back with a trailer this week to pick them up. From what little I know about cultivators, they appeared to be mostly complete. There is a set for the rear and one for each side in the front along with a couple hydraulic cylinders to raise them. Probably a few points missing or broken but figure I can come up with them somewhere. I'd like to get a manual for them to really understand how to set them up. There looked like a lot of linkages on them, which I have no idea at this point how to hook up. I want to use them on sunflowers next year. That’s providing I get the H back together and running by then. I looked for a manual but it appears like they made a number of different cultivators over the years. How do I determine the correct model so I can get the proper manual?

In a nutshell:
The cultivators are effective on row crops, but pretty slow for today's field sizes. If you are playing with 10 acres or less they will do fine.
Two levers with adjustment notches bolt to the front of the rear axle housing (we take off the drawbar first, i think most do because it is not possible to use the tractor for utility purposes with the cultivators on it )
Two pipes with metal brackets for the cylinders attach to the lever handles, one on each side.
S shaped steel bars with a cross pin in one end go in the holes in the bottom of the hydraulic pump, to guide the cylinders.
On the front cultivators there is a 4"X4" angle iron that crosses in front of the bolster just below the grill it is attached to a pair of plates bolted to the front bolster casting, one on each side. The pipes mentioned push on the top of the cultivators on each side to raise them.
The rear unit covers the wheel tracks, and tills the middle of the row where the front tires run.
There is also an accessory tined rake like smoother that is used on the back to break up ridges, but if it is not there, no problem.
it takes two people about an hour and a half to do it when they know how, it will take three or more if it is the first time. Be careful driving into the setup not to puncture a sidewall on the front tires on the sweeps Shields for preventing the sweeps from covering seedlings are valuable.
The cylinders are connected to the front hydraulic ports on either side. Good luck, They work but seem like a Rube Goldberg affair. JimN

Heres some numbers if the shanks are attached to pipe main frame its an H-M 236. If the shanks are attached to the frame using a rectangle solid bar its an H-M 238 If it has some pieces that make the front sections hook to the front pedestal so the will move as the steering is moved it is an N-M 221. I have an I-H parts book showing all the different types and tooling that goes with the H cults such as peanuts,vine lifters,bean harvesters and moreso if you need more info send an e-mail with more descriptions of what you have.
