Hagman, I didn't realize that Gill Rakes are also known as Soil Pulverizers. Are you referring to a Soil Pulverizer or did you mean Landscape Rake (York Rake)?

I don't have much input on a soil pulverizer since I have never used one. I believe they are typically used by contractors to prepare for seeding or new sod. It seems like it is better compared to a tiller than a box blade.
I would think a box blade would definitely be more versatile. With a Soil Pulverizer, you cannot lift the shanks; that is, they are always engaging the ground.
