Lexion Chopper Blades

[Salopian_Will]

Need to change the chopper blades on a 570. What's the best option? Plain or serrated, 3or4mm, spurious or stick with genuine Claas?

Any experiences gratefully received.

You could sharpen them , we are sharpening them with great success .

Sharpen, turn and sharpen again when needed, a flap disc on a small grinder does the job well

Knives sharpened with a flap disc don't last long after , you can't keep the angle right with the flap disc , it will improve them but it's not a good job.

Suppose it depends on how much chopping your doing, thickness of crop and how decent a job you make with a grinder [emoji57] managed to get another couple of seasons out of ours no problem

Then replace chopper bearings after a few days as it was running out of balance[emoji1]

Never had to replace any chopper shaft bearings in the 20 odd years we've had combines with choppers

Thank but these are beyond sharpening. We suspect it is still on its original knives, which have been turned and sharpened more than once.

Any guidance on new knives gratefully received.

Do you chop much straw in Ireland? I thought it would all be needed for livestock.

A good bit of wheaten straw is chopped especially if the weather is bad , there's a big shortage of straw here this year as it didn't yield well last year.

If not with flap disc, how best to sharpen inorder to get correct angle?

Did you ever come to a conclusion on this .I was looking at some spurious serrated blades but they are not available in the correct size for my Lexion 670 is it back to Claas or are there some alternatives out there.
