I'm looking for an affordable planter than can handle a large range of vegetable seeds. Mainly sweet corn but also be able to plant peas, okra, variety of edible dry beans, cucumber, squash, pumpkins, etc. The Deere 71 planters come up quite a bit and seem to be reasonably priced if you stay away from ebay and other places where the food plot guys hang out (deer hunters must have copious amounts of disposable income). I was offered a Deere 494 planter for a good price as well as a 490 planter both local. I'd rather have two rows but could take off the outer two units on a 4-row. Anything else I could be looking for? What makes the 71 such a great planter?
