Kuhn mower knives

[Pistonbroke]

Hi all, I have a Kuhn fc283gII with bolt on knives,bought used with these knives that I'm not that impressed with. The book shows a left/right handed type with a twist. Which is best

We have always used the left/right handed type as shown in the book on our fc283. Never had reason to complain.
With the ones in your picture, I assume you have to swap them to a disc turning the opposite way to use the fresh side? You can't just flip them over as you would with normal blades?

Yes,and maybe just me,but they seem to round off quicker than the old Lely. I know people will say it's a bit tight but if the left/right type look a bit dull it's easy to whip across with a flap disc and you're good to go. Is there an advantage to the ones I have

 

[HCC]

Haha perhaps it is tight, but I also do the same!

Go on..... treat yourself to a nice new set.

Twisted lefts and rights

 

[Thomas5060]

Fit full set of new twisted lefts and rights, you won't regret it not that dear either, bought a box each yesterday at £1.83plus vat per blade

 

[Bullring]

What’s the difference in cut between straight and twisted blades?

 

[1594mac]

And the silly question from me is how do you know which one goes on which disc if they are left and right

Arrow points which way.....

 

[Pistonbroke]

Thanks all. Nobody recommends the ones I've got, so time for a switch

 

[kermit]

We those ones, supposed more stone proof!

 

[ProDrive]

They look like Tarrup blades??

 

[Pistonbroke]

They seem tough but don't cut as clean as I would like

Sorry if I'm being thick, but googling genuine Kuhn blades, they have both bevels on the same face of the blade. Does that mean they're not reversible? The bevel would be on top one way and underneath if reversed ?

Some people fit them one way & some fit them the other way, I always fit them with the wide part of the blade to the bottom, new JD mower came with them the other way but I turned them.
You can reverse them but mine have usually been hitting stones before I get the chance.

Turn the end disc so the front of the disc is turning inwards towards the other discs , which ever way the other discs rotate the downward edge of the blade should be the leading edge of that disc , as some discs go one way and others the other way , hence left and right hand blades, get a new set ,
