What is the row spacing your looking for? The wheel spacing on your tractor needs to drive the spacing of your rows. Does your tractor allow you to adjust the spacing both front and rear? My International 244 compact allows me to adjust my rear wheels from about 36" to 48". So row spacing with a single row planter should be from 36", 40", 42", 44", and 48". This will allow cultivating with a single row cultivator. I plant all my 1/3 acre garden on 40" rows. I plant with a Cole 12MX planter behind a John Deere 332 (diesel garden tractor) and do final cultivation with the International 244 using a cut down four row cultivator. Last year I planted and harvested 12 100' rows of sweet corn plus another 4 85' rows of field corn. In theory with either a multi-row planter or using a offset single row planter (a pain to keep aligned and remember which way to turn) you could plant 18", 20", 21", 22" and 24" row spacing. This would require a two or more row cultivator. Trying to do other than a spacing based upon your tractor's available wheel spacing you are on your own. Growing up in corn country (Eastern Iowa) we planted everything in 40" rows. The rear tires were set on 80" when cultivating using two and four row cultivators.
