That is the shoes, they adjust 1 to 4 inches. Like Tonton said you will get at least 7". My tiller says 6 to 8 inches. 7" is a nice round number and probably more right.I am looking at the current offering for a 48" Tiller at TSC. The specs say they adjust from 1-4". Is that all the depth you can get with these? Am I missing something?
Likely so. We have hard clay right below the surface, so I did some work to get mine where it tilled well:I just go slow and get nice fine tilled soil. Maybe it's just my soil? I have 12" of beautiful topsoil then all clay below that.
Good tips here. I'm afraid I'll be doing similar to yourself, as we have a hard packed clay just below the surface and I am moving the garden to the back forty this year. I'll know soon how much soil I'll be removing and rehabbing. I decided to run the plow through next weekend to get a good look at things (and find the rocks). I plan on tilling afterward then possibly removing the top layer as you did or just adding sand and compost then re-tilling. Either way, I will be adding a silt fence along the creek area to catch eroded top soil before it goes downstream.Likely so.

After that, when walking on the garden, it is really soft. I'm thinking the underground foods (potatoes, carrots, etc) are going to thrive.
- Tilled down 3" and removed that layer with the loader. This part was the longest as I had to go over the entire garden about 5-6 times to get it down to 3".
- Hauled in a 3 part mixture of sand, shredded topsoil, and compost and spread that over the garden
- Tilled again down as deep as the tiller would go to mix it all together
It's also important to note that you should till in two directions, with the second direction being perpendicular to the first. That did wonders for mine.
