I just made hills and furrows in my garden for the first time. Both hills and valleys are atrocious to look at. :)

I remember my grandparents and even my parents when I was young had gardens with perfectly straight rows and furrows just the right width and straight and level. We even used to water by simply filling the furrows.

So how do I do that? Obviously my shovel was not the right tool. I am thinking of some kind of furrower behind a metal wheel or something. It sure seems like I have seen those before.

Of course if I could find one to fit my 10 year old Sears rear-tine tiller, that would be better but either way would be great.

Any ideas? On the manual or maybe a universal fit tiller attached?

Thanks.
