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

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.

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

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

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.

“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.”

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.

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.
