Unless you got a really big garden the best way to do it is to get acouple of long stakes with plenty of nylon string,put one stake in the ground where you want your row to start and put the other where you want the row to end,than use a hoe corner[edge]and make your furrow along that string.Then get you a couple of lengths of stick or rod of some sort the length that you want your rows apart,one of these can be used for marking how far from the edge of your garden you want your rows to start,then lather rinse and repeat.You [in a veg. garden],never plant every thing at the same time,i.e.,I now have some things planted but it is too early for most things.If you put rows in your whole garden now,you'll just have to do it again when you till again latter when you plant corn and tomatoes,plus you don't get any compaction from the tractor tires,now if you are planting an acre of corn or potatoes at once than maybe a potato plow is what you need.
