Subject: Setting up chisel plow

Hi all

We just bought a new to use great condition Glencoe SS7400.

It’s 12 feet wide so 9 shank but the past owner put 3 more shanks on it. Not sure why so it’s actually a 12 shank.

We are mounting a 5 row drag harrow on it to help level after the chisel.

We are going to spring chisel every acre… please say it won’t work, In this area it’s how it’s done. We double crop every acre with a winter forage crop.

Now to my question should I leave it as 12 shank or should I strip it back down to 9 shank? We want it BLACK. I was thinking 4 inch twisted shovels on 9 shank but is it better to run as 12? Do I run 12 and put on 3 inch twists?

I only have 250 FWA HP weighted to 26,000lbs set on row crop duals to pull it do of course that’s a factor.

Any input is appreciated. We have never owned a chisel plow ourself

TIA

Better known as a ' soil saver'.

Will depend on depth and soil type regarding how many shanks you can pull with 250 hp mfwd.

We farm alot of clay

If I can get 8 inches constantly I’m happy

No idea without a location or other info. How does the additional shank match up with the wheels? If you want it black, why chisel?

Doesn't seem like a Soil Saver would be ideal for spring tillage on account of the shank spacing. A chisel plow with sweeps might work better- but if it is now on 12" shank spacing, then it might perform like a chisel plow in the spring. The original owner probably added shanks to make it perform more like a chisel plow and less like a disk ripper.

If you intend to plant behind it, it seems like the more shanks the better. The twisted shovels will move dirt, but it won't be smooth. I don't know that I've ever seen sweeps on a Soil Saver - seedbed preparation wasn't necessarily its greatest strength.
You'll have to decide what is more important to you "turning it black" or a smooth seedbed.

I’m hoping the drag harrow does a small amount of leveling.

But my Lemken 6M power harrow is going to be my second and final pass of tillage. That will smooth and breakup the seed bed.

In that case, I'd run twisted shovels. I'm sure the Lemken will make a nice seedbed.

Keep in mind, I know nothing about your soil.

Straight chisel plowing in the spring is how most everyone used to do tillage here years ago…..many applied nh3 as they chiseled. As more acres were covered by many farmers, the appeal of fall tillage, particularly on fall corn stalks , became the norm. Nh3 was then applied in spring on soybean stubble that had no tillage with a toolbar and the chiseled corn stalks of coc. That way they were ready to plant in the spring. We no till soybeans , but still use a chisel in the spring ,on limited acres , on soybean stubble as we apply nh3. We also put nh3 on with a toolbar to get more covered. But the chisel is the same chisel from 40 years ago that is on 12” spacing on 3 bars. We like 2 “ straight points in the spring, no need for twisted in my opinion. Will leave it smoother and pull easier. One pass with a Caseih 330 ahead of the planter makes it smooth. We don’t do fall tillage , but many do…..most of our ground is sandy loam and not heavy enough for fall tillage.

Standard equipment here on the front of a 9 shank Soil Saver, when they first came out was either a 1066 or a 4430. I don't believe you will have any trouble with a 26000 lb. 250 horse FWA.

Google (or other search engine) “Setting tilt on Glencoe SS7400”. Or similar questions. I had similar unit. Different brand. But you could adjust hitch so slightly higher rear in transport. But level at depth. Is how I recall set. Turnbuckle, and 3-4 sets of holes to adjust hitch height?
Depending on conditions. The extra shanks might cause plugging. If I drove slow. Lots of residue. As I recall anyway it needed to move faster then my tractor could pull it. Got a FWA it did a better job, faster.

If the OPs 7400 has the reset shanks on it like the one in picture, a Glencoe soil saver is not a Glencoe 7400...not even close. A 7400 with reset shanks stays in the ground when the going gets tough. A 9 shank 7400 will bring a 250 hp FWA to it's knees and/or spin out in certain conditions.

We have a 9 shank ss7400 with heavy springs like your pic shows. If we want to bury trash we use 4 inch twisted shovels, in heavy clay we brake the shovels at the bolt holes. If you want to scratch the top 250 horse might work, our 335 steiger and a 9 shank are a good match at 6 mph.

We ran SS7400s for years. We had a couple 13 shanks and a 9 shank. My nephew still has a 9 shank Case/IH 6650 which is a SS7400 painted red. If yours has the reset shanks, it is a good chisel that will stay in the ground. The reset shanks do pull significantly harder than a jiggle tine (spring shank) chisel.

Glencoe never made a 12 shank 7400, how did the previous owner make it into an 12 shank? Just add shanks to each side or did they change the shank spacing? Are all of the shanks the same space apart? Does it pull straight as 12 shanks? Seems kind of strange adding three shanks somewhere in the mix instead of adding one shank to each side. I assume the outside shanks stick outside of the coulter gangs?

We ran four inch twists when we wanted the end result to be "black." A five row drag/harrow will do a pretty decent job of knocking the tops off of the ridges. When it got muddy...or frozen we used to pull a shank off of each side of the 13 shanks and run them with 11 shanks. We were pulling the 13 shanks with a heavily weighted turned up 936 and a heavily weighted 976 Versatile.

An 11/12 shank will give your tractor a pretty good load, a 9 shank would be about right IMO. Especially if you have a few hard pulling clay hills and/or field conditions are less than perfect for traction. Running a MPH or two faster will give a "blacker" finish than toiling along barely being able to pull the chisel even in the best of conditions. We pulled our 9 shank with 4 inch twists with a 8400T or a 8400 FWA with duals, that was a nice load in most all conditions for those tractors. My nephew pulls his 9 shank with heavy straight points with a MX200 FWA with duals, that is more than that tractor wants in some conditions.

Set the depth so that the shanks are staying put and not trying to "trip." Trying to run too deep will only wear out the spring reset (trip) mechanism and you wind up with uneven tillage depth across the frame of the chisel.

If your new to you chisel were mine, I would reconfigure it back to a 9 shank making sure all of the shanks are spaced at 15 inches and are configured in the positions on the frame where the factory installed them.

Drop to 9 and use sixteen inch wheatland sweeps

Subject: RE: Setting up chisel plow

I tried those sweeps for one day on a 7400 with resets longer ago than I care to remember. They didn't cover much and in chopped corn stalks would go through the first time but don't overlap or try a second pass anywhere. Instant plug. I'm pretty sure there are 9 of those sweeps still in the shed somewhere..... I can't remember why but I didn't like the job they did in soybeans either. I also used 4" twists on the factory spacing. No drag but I wanted it a little rough over winter.

Wish I was closer I’d take the sweeps of your hands . I don’t have corn stalks
