I am servicing a Hayter Hayterette mower and need to remove the large metal

And does anyone know which way the disc rotates in use - I suspect that the
bladelets are on the wrong way round!

The blades are actually bidirectional

work out which way it rotates by pulling the starter cord
These are total buggers to remove..not sure the central nut is not
reverse threaded? check.

They have a woodruff key and IIRC a tapered crank as well.

Heat may be needed and a scrap bolt in the crankshaft with a large mallet.

I generally grind off the bolts that hold the blades. and leave the disk
in place till its totally buggered, and then cut that off as well.
