Rotary Disk Mower

In the market for a used 3 point mount rotary disk mower for cutting some grass hay. Only tractor I have to put it behind is a John Deere 5320, that"s about a 6 year old utility trator, and I think it"s rated at like 60 PTO HP.
What size mower will this tractor handle both from a HP standpoint and 3 point carrying capacity standpoint? I"m thinking a 9 foot would be too big but the 7 footer might work? I also see a few 5 1/2 footers around. I"m new to these things, been around sickle bar mowers and sickle bar mower conditioners but not these. What do I need to look for in a used mower?
Thanks

A 60HP will pull a 9 ft disk mower just not as easily as a 75 or 80 hp. I've pulled a 9 ft on a caddy with a Kubota M4900 which is 49 pto hp. If you ever pull a 3pt disc mower on a caddy you'll never want to hitch one to the 3pt again.
 
IT should have adequate power for a 9'. It will have none too much front weight for either a 7' or 9' and I can't imagine going with less than a 7'.... so add front weight and go with the 9'.
I don't understand what all the hoop is about with a caddy. If you're going to shell out more money, buy a discbine and have something.

It's easier to attach to tractor,follows ground better,corners better and takes a lot of stress off of RH tire and axle brgs. If you haven't pulled a disc cutter on a caddy you'll have no idea of the advantages. If one cuts Coastal a conditioner isn't required so a disk mo-co has a lot of things to break/wear out that isn't required therefore a flat cutter is all that's needed.
 
Hitching take 5 minutes if you know how. Can't imagine why a caddy would follow the ground any better... and you lose the advantage of having close control of the end of the bar for trimming work on a trailed mower...
Still don't see any advantage.

I use a JF 165 cm [around 6 ft]drum mower on a Fordson Major. Once it gets spinning I can toddle along in top underdrive but the Tractor needs all its power to get it spinning from a standing start.

I suppose a 9 ft on 3pt doesn't exert a lot of weight and stress on your tractor tire and axle either.

Don't ever try a caddy then but no everyone can hook up a 3pt disk mower as easy as you!!!!!!!!!!!!!!!!!!!!
 
I can't imagine what stress a 1/2 ton mower is going to put on the tractor that a 15 ton spreader with 5 ton of drawbar weight isn't going to put on it...
The trick to hitching Kuhn mowers, and perhaps others is unhooking them with the bar in a vertical position. Then they hitch very easily. If you lower the bar... THEN the left pin is always 6" higher and it takes half an hour of cranking on the adjustment rod to get it hitched and then leveled again.
Ofcourse there's also a bunch of you that don't have Kuhn mowers... so mabey they're not so easy to hitch?

Attach disk cutter and with cutter bar in vertical position I'll bet you more percentage of the weight is on RH axle & tire than the LH side. Therefore during transportation while performing custom baling such as I do driving miles on a blacktop the RH tire will show more wear. Tires aren't cheap.
 
I've yet to see any more wear on the right side than the left side... and we spend hundreds of miles per year on blacktop each year with our two bigger tractors. 2K hours used to be common on bias tires. Over 3K now on a set of radials.... both the same.
I'd hate to think about that extra set of stupid little wheels to maintain on the caddy; the kind that do constantly seem to bring trouble my way.
Whatever works for ya I guess.

I'll never convince you so you keep on believing that the 1000's of caddy owners for disc mowers don't know which is the "better way" to handle a situation !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You're right and they're all WRONG.
 
There's lots of people in the world that never learned the right way to do something so they find another way. Perhaps a harder way. Perhaps a more expensive way, or whatever...
You still haven't shown me one single advantage to a caddy, but if you like it, that's fine with me. To me it's just one more machine to mantain, and I don't need more.

Rod,
I've listed several ADVANTAGES of a caddy addition over a straight 3pt disk mower BUT your too busy telling me and stating everyone other person that uses one doesn't know as much as YOU. If you haven't tried a caddy on a disk cutter then you won't & don't know.

I going to quote you exactly what you just stated and I agree

[/quote]
 
What you preceive to be an advantage, I see as a plain simple nuisance...
It's not as though I don't know how a trailed mower behaves.
I've also long since given up on the notion that a majority of people know anything or are ever correct.

Rod,
What you see as a plain simple nuisance may be the best thing since slice bread but you'll never know because you're already convinced without ever trying it.

It's easy to condone an implement or idea with no personal experience of it's advantages.

I'll never convince you about the advantages of a caddy and I've pulled a disc cutter both ways 3pt and on a caddy so I talking from experience not without actual experience unlike YOU!!!!!!!!!!!!!!!

I stand by the fact that dropping a pin in drawbar hole is easier(simpler) than hooking to 3pt hitch. ENOUGH SAID
 
I'm not sure what earth shattering revelation I'd see from trying it other than my wallet would be emptied for the experience...
Again, it's not like I've never run a trailed mower... and the ones I have run are a pain in the hole without a power tounge.

I guess it boils down to that down here in Texas will cut hay fields and leave obstacle courses for zero turn lawn mowers.
