| I wouldn't recommend anything wider than 4 inches. There is only a 6 inch shank spacing and if you try to use more than a 4 inch sweep, plugging occurs in many conditions. I'll never forget the Salesman and Customer who insisted I install 7 inch sweeps on his new 1300 only to make a trip to his farm to take them all off for the 4 inch size I told them both was needed. Just friendly warning. |

| I have 2 of them…both 28’ and both have well worn sweeps that measure about 9” |

| You say 4"...do you measure wing tip to tip it bolt to tip? |

| 4 inch width of cut. Tip to tip actual width might vary a little from one brand of sweep to another. 9 inches wide would be an absolute waste around here, as it would be plugged all the time. Shanks are under more stress with wider sweeps. |

| So 4" cut on 6" spacing? |

| That's what I use. Your results may vary. |

| so there is a 2” space between that doesn’t get worked? What kind of soil are you working with? |

| With the offsetting / staggering front to back, all of the ground gets worked. No? |

| No. Spacing refers to how far apart shanks are side to side viewed from the front so if using 4in sweeps on 6in spacing there will be 2in of unworked ground. The sweep may well disturb the soil beside it. Bury it and go fast is probably the most effective? |

If you stick your shovel in the ground does it make perfect slice and move only the dirt cut by the shovel or does more dirt crumble in and around the new hole? One reason not to work wet ground. wet dirt smears, slices, and packs instead of lifting up together and crumbling.

Yeah....I got to thinking about that later after I posted. I totally agree with you.

The following text (“-“)was copied from an Iowa State Extension tillage report. April 2004. If you’d like to read whole report it’s weblink is at bottom of this post. “Tips: Secondary tillage When it comes to secondary tillage -- preparing the soil seed-bed for planting -- most farmers use a field cultivator. Field cultivators come equipped with a variety of soil-engaging points, from narrow tines to wider shovels and sweeps. Tines, shovels, and sweeps come in many shapes and sizes. The shape determines what the soil-engaging points do in the soil: narrow tines tend to fracture the soil, wider sweeps tend to lift and mix surface soil and residue, and are commonly used for chemical incorporation. Setting a blade at a sharper angle (or 'pitch') usually means that more soil will be disturbed. Implement weight is supported by the underlying soil. Therefore, wet and nearly-saturated soil can be compacted underneath the secondary tillage.” https://crops.extension.iastate.edu/encyclopedia/tillage-implement-design-and-its-effect-soil" rel="nofollow - https://crops.extension.iastate.edu/encyclopedia/tillage-implement-design-and-its-effect-soil |

"Bury It" My experience with modern/heavy planters, is that firm soil plants much more uniformly than very loose soil that causes planter gauge wheels to push. I guess this was true on old equipment too. You plowed a field to work it, only to cultipac it a couple times to firm it back up. Especially running a chisel plowed field, I run just deep enough to level and break up clods.

| I like to run my IH 4800 2 inches deep. Usually takes 2 passes on fall chiseled ground. The first pass doesn't totally smooth it but the second pass makes a nice seed bed most of the time. |

| So it’s better to have narrower sweeps. My neighbor has a perfecta and put new sweeps. Not exactly sure size. Know bigger and now leaves like groves in field |

| Well, I guess it depends on what you need/ want, and to some extent the cultivator they're on. I use 7 inch sweeps, and yes, you probably wouldn't want to plant right after a deep pass. I like the job it does. It has plugged a few times in corn stalks......I pull a rolling harrow behind it on the second pass and the field is baby-butt smooth. |
