Much of what implement you choose is going to depend upon how much ground you need to cover. There's no question that if you have a tractor with a PTO and three point hitch I wouldn't even mess with ATV or UTV implements. However, if you're interested - For UTV Implements I would look at Quadivator or Monroe Tufline. They make the best quality that I have ever used. For cultipackers, I just bought the cultipacker (ATV-UTV) from Best Outdoors last year and would highly recommend it! I bought the 4 foot model and I'm going to by the extension to make it an 8 foot this spring. He has either ATV models or 3-point hitch rigs.
