Anybody ever build a row maker/raised bed for behind a rototiller

[hoardac]

I have seen some made from wood and some from steel but they only make one row and are fixed. I need some ideas for adjustable size row making with a 5 ft tiller. I have narrow tilled rows I use. I am farming in between orchard rows so I have about 7 feet wide to work with. So I have to plan my crops in a different way some rows are narrower some are wider trying to make the most with what I have tilled. Someday I might have more land cleared and can just do standard rows but until then. Any and all ideas welcomed. I hoed up 1600 linear feet of beds this year, still have not got the greenhouses done. That is enough for me something has got to change, getting to old to do everything by hand. Thanks for any help.
