Best tines or cultivator arms for weeding carrot rows

[videorov]

Looking at diffrent attachments for my 3pt hitch on 35hp tractor to go though rows of carrots
and keep them clean of weed pretty well. I also have a Mantis tiller for touch up if I need it.
I have around 1 acre garden that will be all rows of carrots.
I seen some pineneedle rakes that might work too and you can take off and move around
the rake spring wires to space around your rows. Also looked at single row cultivator where
the one row goes through the middle and 3 arms scrap the ground on each side of row.

The pine needle rake sounds like a good idea for small weeds. What brand and model tractor do you have. What row spacing are you going to use. Any pics of your garden, tractor, other implements, etc
