Started this instead of hijacking another thread. It seems like whenever someone posts about a snap coupler disc to knock down plowed ground, people immediately say you need a heavier disc. Well then, what were the options? What discs were available when the B, C and W series were new? I'll admit I don't know a lot about the B or C series, but, weren't they meant to be the do everything tractor for the small farmer that could probably only afford one tractor? What was available from Allis Chalmers as a "heavy disc" for them? Weren't they marketed as a set? You bought a tractor, a plow, a disc and either a drill or planter? Most of what I've seen, it was a mounted disc. If the snap coupler mounted disc wasn't meant to knock down plowed ground, what was it meant for? ------------- Looking at the past to see the future.

We always dragged plowed ground with a 3 section harrow,broadcast fertilizer and disc it in then one more pass with the harrow,then plant. Spring plowing and the disc wasn't buried. This was with a WD. Old days weren't for sissys.
These days I sit in a climate controlled 8070 and rip it up in the fall with a 9 shank disc chisel. Usually 2 passes in the spring with a field cultivator and plant. I'm 30 yrs behind the times but it works for me. Dad started out with an Oliver 8ft drag disc....the kind that you set straight to travel.

You have to remember that B's started a tractor revolution. It was meant and marketed to farmers being weaned from the horse. Horses didn't do well with a heavy disc harrow, and the whole small farming culture was plow, drag harrow, cultivate several directions, harvest... Now if you had a bigger tractor, you might buy a #30 or 40 lift type disc, for say a W series tractor, all of this was sort of in its infancy, late depression and through WW2. It took getting through the depression, and war, before the manufacturing and economy, was ready for mounted equipment to be introduced and produced... ------------- Source: Babylon Bee.

One of our neighbors had, what they called, a set of AC Snap Coupler bog harrows. If I remember correctly, they had large discs, maybe in the 20" or bigger range. I think they were only about 6' wide. When I was a teenager (late 60's), Dad borrowed them. He sent me to pick them up with the WD45. I knew the discs were heavy, but when I drove across the railroad tracks, the front wheels came in the air, and the discs touched the ground. I've never seen another set of discs like them.

| My grandfather said sometimes the rear tires of the tractor were more effective at breaking up plowed ground than the disk |

You might be confusing this with guys trying to talk about disking UNPLOWED ground with these little disks. They work well in ground that has already been plowed, but they won't do anything to try to disk unworked ground. In The 70's as tractors got bigger they started coming out with heavier disks on 9" blade spacing. These typically disk up unplowed ground just fine. So sometimes guys think they can do the same thing with the little light disks on 7.5 spacing, but they aren't heavy enough.

| Three trips before planting. First trip with the disc the way the plow furrows laid. Second trip also with the disc at an angle to the first trip. Third trip with a 4-section harrow at another slight angle to make planter marks easy to see. |

[/QUOTESeems that bog harrows were more common in the South,used to be an auction in NC with AC equipment about always had a bog harrow.

Nope, not confused. Started this post because of comments in Pointer Hollow Farms post. But have seen it before in other posts. ------------- Looking at the past to see the future.

I have a #20 disc that I use behind a CA. I think the problem that most are having with poor results when using the #20 disc harrows is: they are not working the ground under proper conditions. With NO-TILL having been around nearly my entire lifetime, those that are younger don't have experience with plowing and working ground and what the proper conditions should be. With my # 20 disc I have a utility pole hooked to the back that is a bit wider than the disc and with plowed ground that isn't too wet it will knock it down level with a single pass. My disc is a 8' model with 28 blades that are 16", with a 7" spacing and scalloped blades on the front gangs. This disc doesn't do much in unplowed ground. it will do OK when following the coil spring tooth field cultivator I have. Now for wet ground I have a #40 disc that will mix water into a pull track very efficiently. My #40 is 6' and has 16 22" scalloped blades on a 9" spacing and will do fair in unplowed ground that isn't too dry and hard. It is really too aggressive as it's set for plowed ground. The angle on the #40 is adjustable and with the angle lessened it would do better in plowed ground. Bigger newer discs that are heavier for larger tractors tend to ridge ground because those using them want to go too fast. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |
