help decision

[outdoorlover127]

I have 3 pcs of equip that I don't know what they do or which to keep.
Sorry no pics, if I am unclear I will try to post.
I am told all 3 are cultivaters, I was also told 2 are multipurpose plows and 1 culti.
I think I want to keep 1 to drag debri, rough up for food plot etc.
1 looks like flat spring steel curved, no adjustments.
1 looks like culti pics I have seen with movable steel blades and a single round disc in center
the 3rd looks like #2 but has big springs attached to the steel blades.
Not farming mainly just cleaning and maybe a food plot or 2.
I would like to sell 2 so I can get roll over blade.
So, with this confusing info, can anyone suggest whoch 1 I would want to keep?
Thank you for looking
Dennis
