Here's my experience on food plot equipment. I started with a Honda 500cc liquid cooled 4X4. It could not do the job! I could not pull a drag big enough to do two small food plots in a weekend. You are correct unless you are planting in a sand soil or a really loose soil you won't pull a disk with an ATV. The light weight equipment is more toy like than serious food plot tools. Frustration will set in quickly. So what do we do now. Friend, family, neighbors, seems like equipment is close by you just need to spend time finding the people with equipment. It could be cheaper to have a nearby farmer plow/disk for you. Then finish with the ATV. Sprayers can be utalized with ATV's pretty well. We use an old Ford 9N to drag with, a small JD dozer to pull a double set of disks, I have a 12v spreader that mounts on the back of the ATV ( Cabelas'). NW PA soil is clay based and is not easy to work with. It's all enjoyable for me, the deer, turkeys, and bear all feed in the plots getting better nutrition than they could otherwise. Its also not cheap to do, I have cut costs by using farmer quality clovers/products vs the high price advertised food plot products. Good luck, its fun, and the animals will come if you plant it!
