Rotary Cutter Sharpening shredder, bush hog, rotary cutter blades.

[N80]

Must admit that I rarely sharpen my blades. Last time was probably 5 years ago. But remember, they do not need to be 'sharp'. They need to be properly shaped but do not need an 'edge' on them.

To remove the blades on mine requires larger sockets and socket handles than I have. Suppose I could borrow them from my B-I-L down the road but I hate borrowing tools.

Mine probably has same sockets on it. You watch the video in the first post I had the shredder / rotary cutter up on end. I think it is faster than removing the blades.

That's what I do. I use the loader to lean it up against a tree then sharpen from there. The nut to remove the blades is huge and is accesses, if I remember, from a hole in the deck so you cannot access it from below if you need to remove the blades.........could be wrong about that............

I believe you are spot on.

You don't need to remove the blades to sharpen with a grinder.

Last week I sharpened the blades on my brother in laws bushhog without removing them. I used a 9" grinder blade and sharpened them to a sharp edge. All he cuts with it is grass so a sharp edge will require less HP and make a better cut.

I positioned the blades to the back of the mower(had BIL hold drive shaft in position), used a c-clamp to immobilize the swinging blade and just ground it down in less than 2 minutes to a knife edge.

The OP had mentioned removing the blades as part of regular maintenance. I never have for reasons mentioned above.

Some people do remove the blades and even try to balance them like lawnmower blades grinding the same amount off each side. Of course I dont. I just stand the rotary cutter on end or side and grind away like in my video I posted.
