Anybody familiar with and/or using a Vermeer 7120 moco? reliable, cost and frequency of repair. Can I pull this in heavy alfalfa with a 185?

That's a 9' cut with conditioner. Vermeer has used the Lely cutterhead for years. It's a very good cutterhead with fewer parts than the Kuhn gear type and should be just as reliable. I believe the old gray New Idea mower conditioners used a Lely cutterhead too. I cheacked an old beat up one out and it's cutterhead had very little play. I think the New Holland cutterhead makes one similar to Lely but it doesn't seem to hold up as well.
I think you should be able to pull it with a 185, as the lely cutterhead uses less hp than the Kuhn gear type, but I would think it'd make it bark. Disc mowers in general take more hp than sickle mowers.
Vermeer is a good family owned company with good customer service.

If they don't have gear drive, how are they driven?

I have a nh617 9 foot three pt hitch disc mower I use on 185. Mow 50 acres of hay twice, some three times and 100 acres of pasture. Can't notice any difference between running on end of field with no hay, pasture type junk and very heavy hay. Goes thru anything like a hot knife thru butter. Travel as fast as you can comfortly sit on the tractor seat. Bill

The Kuhn style cutterbar is all gears running the length of the bar. The Lely style has bevel gears under each hat but has a shaft running between them.
Hesston, New Holland, HayMax, Vermeer and others use the shaft design copied from Lely who first designed it. So it's called the Lely design.
Anyway, so from what I can tell and have learned the Kuhn style is called gear style while the Lely style is called shaft driven.
Vermeer gets their cutterheads direct from Lely and they are good cutterheads. New Holland makes their own and it seems to get loose more on older machines from what I've personally seen. Hesston gets theirs made by some European company but it's not Lely and I've heard they don't hold up as well either.
The Kuhn/Gear type head is a very nice head too. They both have their advantages where Lely's is primarliy that they have fewer parts and use less hp. Kuhns are probably stronger. Lely has the quick clip system on the newer ones and that's nice.
Just from research and checking out older machines I'd either get a Vermeer, Kuhn or Krone. A lot would depend on who gives you good service and price. Vermeer is a good family owned company who cares more about it's customers than a Wall Street company, like AGCO, would.
BTW - I'm not familiar with MacDon cutterheads but they look like good units too though larger.

Thanks for the good info. I'm still on the fence as to disc or sickle plus's and minus's for both but one of my issues is gopher mounds and I think the disc would be better there.Probably should have two plus a sickle mower but thats not going to happen.

You cant go wrong with any Vermeer product. They are always a little overbuilt, tough as nails.

sometimes I walk out to my shop and look around and think "Who's the idiot that owns this place?"

Gophers and sickles? We mow all our hay with sickle mowers. Really don't know what your problem would be with gophers. You go throught the mound and keep going.
Id sure like a rotary at times though. Moss etc. Less plugging up in spots. Lot of $ for a little convience. Know a couple of guys that have parked their Rowse or Kosch for one of these. Mainly ground speed though I think.

Once you try a disc mower you'll go that way. I cut six+ foot tall cover crops this year with my brothers and it went right through it. A lot of what we're planting now is high sugar rye grass and you really need a disc mower for that unless you have all day.
