Side-delivery bed former?

[oldgrayfellow]

I'd like to build a bed-forming attachment to be mounted on the rear of a 4ft tiller. Here are links to a couple of existing (larger) systems:
YouTube - Banker Wings (1) 61 4 0824 1998 0408 241 998
YouTube - Cucchi Baulatrice Bed Former www.cucchi-ma.it

These form a raised bed centered on the centerline of the tractor.
But what i would like to do differently is to make the device so it diverted all the dirt out past one end of the tiller (actually out even further than the end of the tiller itself). That is, i want to form a berm of dirt past the outside of the tire tracks.
I was thinking of mounting a grader blade off the back of a standard 3pt tiller, at an angle so it would funnel the dirt all to one side. The blade could have a 45deg angle attached on the trailing edge, so it formed a (single) 45 angle on one side of the berm.
The reason i want it to go all on one side is so that i can bank the dirt against something which i can't run over with the tiller itself.

Any suggestions or comments? Feasible? Important points for design/use?
Will it require substantially more horsepower than the tiller alone?

3pt hitch box blade or a rear blade i think is what you are looking for perhaps?

rear blade for snow plowing. are generally turned at an angle. to help push snow off to one side of the tractor. if ya pitched one of the arms up, you could get more of an angle.

box blade, would be better suited for creating a ditch and moving the dirt some place else.

Yes the rear blade sounds like the right idea, except think i would want to mount the blade behind the tiller on a fabricated frame. Trying to pull a snowblade alone through normal ground would probably take more horsepower than i've got available (18hp diesel), or else i could only take a little shave at a time.

But letting the tiller puff the dirt up completely loose will hopefully make it possible to do much more depth at a pass than the blade alone through settled dirt..

Great suggestion also about raising one of the 3pt arms, to get an angle. I'll also chain the arms over all the way to the right, to position the tiller unit as far right as possible.

A box blade i already have, but as you say it can't help in this application..

not sure how much ya gotta do.

but fluff the dirt up first with the tiller, and just switch out to a rear blade. take it slow and a little bit at a time.

on another thought perhaps redoing a one bottom plow and off set it the blade.

remove the tines of the tiller. and mount like a snow blower blade under neath the tiller. but put the blade in such a way that it would move the dirt out to one side.

or do a quick test, remove the back gate on the tiller, weld on some L / T brackets and get some 2x8's for a side blade and see what happens

I don't want to discourage your project but I think boggen is on the right track. Moving dirt sideways takes a lot of weight and/or downpressure to hold the blade down and enough traction to keep the tractor from spinning or crabbing. I think it may be asking a little to much of an 18 hp tractor to be tilling and grading at the same time, but as boggen suggested, if you can tack a temporary blade behind the tiller it's worth a try.
