I would like to get a3pt disc for my JD 650. My dad and I have different doubts for this tractor. I think a 6' disc would be the most this could handle. He feels the most would be 4.5-5'. I need at least a 5' because that's the width of tires and chassis at rear. Any info is appreciated.

You are going to be pushing it to pull a 4 foot disc with 16 HP at the engine. Tractordata has the width at 41" so perhaps you could narrow the tires to get inside 4 foot wide. No way can you pull a 6 foot disc even a light weight one. A good 6 foot disc will load up a 4 WD 45 HP tractor. Better stay with a light weight 4 foot and watch the lift capacity. My brother in law has a 750 and without the 4 or 5 suitcase weights on front, it barely lifts a 4 foot bush hog while keeping the wheels on the ground and they are much lighter than a disc.

A 4' disc is all you wan't for a 650 4wd tractor and if you have a 2wd model I would recommend you get a 4' tiller instead.
I have pulled a single gang 4' disk no problem. I don't want to change tires, as I have $500 in the ones I got.(tractor came with wide turf tires, I converted to bar tires.) I will prolly go with a4.5' disk and jut overlap. I have a 4' bush hog it lifts no problem, and keeps front wheels on ground with no additional weights.
I really want a tiller, but for now I have a piece of my property that used to be a pine tree patch for Christmas trees that I cut down and have dug the stumps up. Now i need to level the piece and don't want to risk breaking a tiller by the old roots or a missed stump. I've tried my box blade but it can't level like I want

I often hit rocks the size of bowling balls with a tiller, just get one with a slip clutch and keep it properly adjusted. Tillers are tougher than most people think. Forget the disc if you have turf tires. Seriously I have wound up 5/16" solid steel wire, hooked an old steel drill line 1 1/2" diameter, roots of all sizes and many rocks without damaging either my Howard or Deere tillers. I have broken a couple of tines over the years but they are easy to change and about 10 to 15 bucks.
Get a forward rotation tiller and you will be fine.
