Optimal way to form windrows on former Willow Bog

Seek advice on the best way to go about forming the windrows for a one acre hugel culture project.
Willow bog has been drained via perimeter. Ditching.
Willows have been cut down and removed.
Roots have been pulled up and shredded with cultivator.

Realistically, forming continuous windrows requires a multi-axis blade plus a substantial machine. In addition, coordinating that with the wood and branch and other compost material, core adds substantial complexity.

One possible tactic would be to form the core of the Google row and then using a track track loader to both reach over and pull soil and push from the near side.
I know that entails considerable farting around and may produce rows of variable straightness end uniformity... I assume that some clever Hermes have figured out a practical pragmatic non-industrial way of doing this

I don't know about 'non industrial' on that scale...I think Sepp Holzer used diggers for his hugels.

I just make one (mini) hugel at a time as I have the time and energy. Renting a machine may be the best option perhaps if you need the site prepared more quickly. I think some variability can be a good thing too.

I was not familiar with windrows so I asked:

A windrow is a row of cut (mown) hay or small grain crop.

Bogs are really productive, valuable ecosystems. Have you considered making it a version of chinampas?
