Wow another scenario thrown up! is this right a 4 rotor tedder isn't as efficient in tedding hay because its drum diameters are too large?
That depends on the rotor diameter on the 4 rotor. I have a 4 rotor that has smaller rotors than some 6 rotor tedders, making it perfect for hay.

With smaller rotors, the tunes are sweeping the ground more closely, for more of the working width. So yes, more, smaller rotors might be marginally better, but also considerably more expensive and more gearboxes to go wrong in the future.

On a given budget, i’d Rather have a new 4 rotor than a used 6 rotor, or a newer 4 rotor rather than an older 6 rotor. Unless you are tedding lots of acres of course.

I've just found this post from @Martin Holden which explains it very well.

The hooked tine patent maybe coming to an end, however the idea cane from necessity as opposed to a “light bulb” moment. Bigger diameter rotors which Lely and others adopted means that when the rotor is pitched forwards the contact at crop level is minimised due the angles involved, so a more horizontal tine overcomes that. Smaller diameter rotors with more vertical unequal length tines do just as good a spreading job. It’s all in the mind and hype.

When I started out I could only afford a 4 rotor but if you can stretch your budget (or take advantage of finance deals) you would be best to get a small 6 rotor machine, something between 6 -7 metres.
 
I have about 20 acres of good hay grass, so what did you go for in the end 4 or 6?
Mine is 4 rotor. Takes 2 x 10 foot mower rows. Alot of 6 rotor machines use same size of rotor as the 4. One needs to check the specs carefully. It is incorrect to assume all 6 R machines have smaller diameter rotors than their 4 R counterparts.

Most of the manufacturers like to make claims on how many mower rows their Tedder will take. Surely an irrelevance in hay, for anything but the first pass?

We used to have a 4 rotor Kuhn but it was a proper b*tch in heavy wet crops, so much so I’ve seen us head back into a field with a hand fork to level the big lumps before baling, now have a 6 rotor Lely and never had this problem and it will operate a a far faster forward speed.

It can even be irrelevant on the first pass too as some people do this at an angle to the mower anyway.
I have tried this but seems to work better for me to follow mower initially.
 
With a 4 rotor machine of any make on the first tedding you will have a wheel on each swarth with a 6 you will be straddling one and bringing one each side so it’s easier to clean the ground
I dont agree with this claim at all.
Yes each wheel is on top of the swath but it doesnt matter cos rotors 1 & 2 and 3 & 4 are rotating into each other whereas the gap between the swaths is presented to rotors 2 & 3 which rotate away from each other.

Don't buy a 4 rotor tedder of any sort would be my advice in all fairness. 6 preferably 8 in all seriousness.
Very true if on wet ground as straddling a middle row is massively better if tedding 3x 3metre rows than driving on 2x 3 metre rows as mud is very damaging to stock

I had a customer with a trailed Kuhn, I don't know the working width but it had 10 rotors and when I had a go with it the work-rate was nearly hilarious.
I bought a 12 rotor Kuhn out of Italy a few years ago. Paid about 7.5k plus almost 2k shipping. Needed a fair bit of work even though only done 6 seasons. Must have turned most of Italy! Fantastic to use, spreads anything evenly and rips all lumps apart. totally stable on steep ground unlike the previous krone that rolled forwards out of work and missed the stuff. Output is amazing but the big difference is even drying in hay with very few green lumps at baling time as the small rotors caught almost everything on the first pass..
