I really like the sound of that. Different makes/models have different shear mechanisms and I was wondering at this point which might be better. I also like that each module is separate instead of a complete bar to rebuild if needed.I have a NH6730 with the shock pro hubs and I really like it. You would be able to probably go to the 6740.
The shock pro hub is designed to shear a 70 dollar piece instead of ruining a gearbox. I also like that each module is separated and has its own gear oil. No contamination if you do bust a gear and also better for working on hill sides.
That is about as easy as it gets. Only thing better is just stay out of the rocksKrones have a roll pin under the turtle that shears off. If you ever shear one a punch, hammer, and $2 roll pin will have you back mowing.
I tore my Agco up last year on the last round in a field when a small limb got lodged in between the discs. About a half second cost me over $1500 in parts and two days to repair. A disc shear on the newer ones and I would have been back in business in a few minutes instead of the mower torn all to pieces.That is about as easy as it gets.

I want a 3ptThe shaft that the spins the turtle is also threaded, so if the pin shears the turtle will unscrew up out of the way and not hit the others. The biggest worry I have with these is if you go many years without shearing one, I think everything could rust together and you might as well not have it.
New Holland has their shock pro setup on many models, which is pretty good from what I've read, but can "domino" with a hard impact, meaning that you will break the initial hub, and possibly adjacent ones from the turtles hitting together when they lose time.
There are advantages and disadvantages to different cutterbar designs. With a single gearbox assembly, changing the oil is easy, and there is less wear because everything is well lubricated. However a loss of oil or internal failure of one part can destroy the whole thing, and you need to be careful running on slopes.
Modular bars are nice because any failure will be confined to one module, however there are several stub shafts that will wear out between them, and changing the oil/grease in all of them is a pain.
I don't believe that the shear protection is quite as important on 3pt mowers. They are light enough that they can just ride over a lot of stuff. Mower conditioner headers are a lot heavier and tend to get things jammed into the cutter bar more, plus you have the rollers that can kick things up or toss it back and forth.
We have a Vermeer MC840 and a New Holland DB313R that is a new arrival. I've never really liked the Vermeer, but the NH has been working well so far.
Vermeer and Lely are involved together somehow, a lot of Vermeer mowers have Lely cutterbars.
JL, were you looking at just a 3pt mower, or a trailed mower/conditioner?
I would love to try one with a caddy. Seems it would be much easier on the tractorA 9 footer without a caddy Is gonna give a 60 horse tractor all it wants in good hay. I just cant imagine a small limb causing a bunch of damage to a cutter.
I have a 90 hp tractor, but I like using a smaller tractor to get around in some of the places. IMO a 9 ft is to heavy for a 60 hp tractor to carry as I looked at a 8 ft mower and it could be all 60 hp wants. On the limb thing I could not believe it either but it happened as somehow it got between the disks as my Agco does not have a slip clutch. Talk about proud of parts as I almost junked it when the dealer told me the price, but I have used it a couple years now. Putting the disc mower back together I figured would be a breeze, but timing those gears a manual is needed.A 9 footer without a caddy Is gonna give a 60 horse tractor all it wants in good hay.
