What are you going to be using the disk for? Before plowing, after plowing, or both? What will you be planting? Notched is better for breaking into hard ground but the blades will last nowhere near as long. I have changed both of my 3-pt disks to plain blades and they work fine, especially on plowed ground. Another option is to have notched on the front and plain on the rear. Another choice you will be seeing is either 7.5" or 9" spacing. If you are preparing a seedbed you want the 7.5" spacing especially on the rear.
I use a 10ft Ford 3-pt disk on my New Holland TD75 and it pulls and lifts it fine. The disk has 32 18-inch blades, but it is not a super heavy disk; it does the job for me. I also have a smaller MF lift-up disk with 24 blades that can be used on smaller tractors.
A new disk harrow will be expensive, maybe keep your eyes open for a good used one, keeping in mind the repair costs for worn out blades, bearings etc. If you buy a new disk you will probably want to spring for scrapers also.
If you're looking looking at new some brands to consider are Land Pride Land Pride Disc Harrows , Taylorway-Pittsburg Hay King K&M Mfg. Product 5 and Monroe Well Built, Performance Driven - Monroe Tufline . There is always John Deere Frontier stuff and even Norhtern Tool has some heavier 3-pt disks. So far I've only purchased used, it's pretty easy to look at a disk and tell if it's been bent up, welded up, abused etc. Some of the older disks are better for finish work because they tend to have the narrow blade spacings and the frames have more flex or float for the rear gangs. I think one of the Monroe-Tuffline units has rear gangs that float.
As far as your plow, if you have to change the tractor wheel spacing you might as well change both sides as long as the new spacing is compatable with whatever other work you'll be doing.

Keep in mind that ballast, GVW and soil compaction all go hand-in-hand.
Because of what I do, I never load any tires and just run OEM rear wheel weights.
Too much ballast= adverse soil compaction, adverse component wear and accelerated tire wear.
Too little ballast= wheel slippage, adverse tire wear and over crop damage from slipping wheels.
I see op's running a field with the FEL raised. I'd be scared of finding a hole or slipping a dead furrow and flipping the tractor, not that I plow, because I don't.
Moldboard plowing in this area is almost non-existent. Everything is no-till or chisel with rolling harrow now.

I have a friend that has the same tractor 4-14 in any but ideal conditions would be way to much for a 65 horse tractor. A rule of thumb for p-low size in average conditions is the width of cut plus the number of bottoms squared. So 4 x 14 is 56 plus4 squared is 16 so you are looking at 72 P.T.O. horsepower. The reason for squaring the number of bottoms is the farther you get behind the hitch the harder it pulls. Got this formula from a tractor dealer rep in the mid sixties and most of the time it stands close. If you have bottomland with enough ballast you may can get by with 4-14 but if you have hard clay you are you are looking more at 3-16 max.

if i were looking for a used disc these are the brands i would look for first.bushhog,international,john deere ,rome ,tuffline,taylor way and athens.i would get notched blades.they do cut better.it will take a long time to wear them out.
