>Was there an end haul of material that had filled the box?
No, that was a single pass of 100-150'.
>As you move along and the blade becomes full, what do you do with it?
Because the swale was just roughed in originally, my first finish pass required me to dump the box about half way. Then pull it away with the FEL. Then resume that pass.
Because that pass took out the bumps and filled the bottoms, I was able to haul the box all the way on the subsequent passes, then just scatter the dirt. You can really make a fine depth adjustment with the toplink.
>I am thinking since the box is angled the you couldn't just raise the box a little and skid the material to the end without it dumping out.
Yes you can. I chose to set the cutting height pretty shallow for the length I had to run and and almost didn't make it, but did. Interestingly, the gauge wheels allow a much smoother feathering effect, tilted or not, than I could ever get without the wheels.
>Is the final swale pictured from a single pass?
The part in the foreground was roughed in some monthes ago so it took 4 passes total. The part in the background is new and took 3 passes ... ~4-6" deep.
>Is the swale to receive sheet flow or to transport water from an upstream puddle? Asking because it appears that there is a sidecast berm that would prevent sheet flow from being picked up.
Sheetflow, from the left only. The pics are a bit misleading anyway. Sidecast is minimal, if any and will probably wind up getting scattered with the mower. Eventually I'll cut the other side so it looks more like a valley gutter rather than rolled curb and gutter.
Cheers!
