Farmall front cultivators mechanism

Hi,

I was wondering how the front cultivator mechanisms work on the Farmall tractors. From the photos I have looked at it looks like there is a bar that lets down both sides at once, which would ruin the plowing clearance on row crops as the vegetables would run under the belly and hit such a bar. I have looked at the John Deere 900hc and it has curved bars on either side that are independent so that when it lets down to plow next to the plants there is no bar under the tractor. Can someone shed some light into how all these cultivators drop down and or limit clearance?

I just said this in your other thread:

(quoted from post at 05:55:38 07/17/12) Hi,

Yes that is what is confusing me about these tractors. The John Deere 900hc has plows that come down from either side, there is no bar running across the belly. If the plows run on a bar across the belly it pretty much ruins its ability to cultivate for me.

The 900HC is a whole different tractor. Granted it is a high crop, but it is 40 years newer and will run about $15,000. It stands to reason that high crop tooling has come a long way in 40 years.
 
You are looking at the pics probably cant see good enough. The veggie models do have a bar clear across but those models had long shanks so you still had like 20in of clearence which would let you do some pretty tall plants. When most plants get that high they dont need any more cultivation. The standard cults didnt have those bars and over the row there would have been plenty of room.
 
This is my Farmall Super C with cultivators in place. That's the planter hopper still attached. The Super C was designed to do multiple tasks. I have the planter bottoms, fertilizer injection knives, and cultivators. I'm looking for some disc hillers' next.

All attach to the universal mounting frames mounted on each side of the front of the tractor.
Implements are raised and lowered by the touch control hydraulics from the tractor seat. Controls are the 2 levers just below the steering wheel. Rock shafts are in the center of the tractor. It has 2 rock shafts so the you can lower one side independently of the other or both. This is really cool! At one time I had this tractor set up as a 1 row tractor with planters & fertilizer on left and cultivators with fertilizer set up on the right.

An H or C cultivator for row crops such as corn and soybeans have independant gangs with no crossbar connecting , not sure about vegetable set-ups though.
 
IH built cultivators in a wide variety of configurations. You need to configure according to the crop you are cultivating. Cultivators for small vegetables (which are normally planted in a variety of narrow row spacings) used long horizontal tool bars. This provided flexibility on setting tools to the proper spacings. Cultivators for tall plants have tool bars configured to not pass directly over the rows.

I've never seen anything on a JD 900HC that didn't look like a copy of something on a Super A.
 
I bought a set of hand lift ones for the front of an H/M. I configured them to hydraulics. I cultivated corn until it was about 12-15 inches high then let it do its own thing. Here are a few pics of mine.

You see the pics of the SC front cultivators. My dad had too much corn for the two row operation especially when we had to apply NHNO3 using the side dressers. I have seen him work corn that was 3-feet tall. Some stalks would break especially early in the morning with him wide open in third trying to catch up. It was the rear axle that would break the stalks and not the cultivator.
 
Hi Mike,

Yes that is what I would be looking for, independent so that nothing crosses under the belly to hit the crops. Are those made for the super A as well?

Hi Gene,

Yeah I have looked into buying a Super AV but it does not have the cultivators with it. I know the clearance at the front is 27 inches and see that you mentioned that the correct bar would cross over the belly and limit it. Is that correct?
