One thing you didn't say,was how big are your food plots, I use everything from 4 wheelers, to kabota tractors, to John Deere 40/20 tractors,,I'm maintaining 20 acres of food plots and 60 acres of CPR land which has to have 1/3 disked up every year,,,and then you can plant oats on it to stop run off. If you only have a small amount,,the 4 wheeler will work good enough,for larger areas I'd go with a tractor.
Good luck hunting this year everyone, and be safe
