This was one reason I got rid of the bloody hover when I could see to mow
the lawn. Who designs these things.

Hi, I've got a Black and Decker (approx. 20 years old) electric hover
mower with a metal blade that I want to remove as it has got badly
bent. However removing the blade is proving a little difficult.

The blade is held in place with a plastic (nylon?) bolt. I've tried
using the classic "Flymo" spanner (same size) on it but it broke (!).
Then I tried doing the same with an different spanner turning in a
clockwise direction. Logically, the bolt undoes clockwise, due the
direction of rotation of the motor, but I'm not sure if this is
actually the case. I didn't break a second spanner!

Then I tried mole grips on the bolt, and a length of scaffold pole
over the blade, and squeezed the two together. This resulted in the
blade turning on the shaft, and the bolt staying put.

What do you reckon I have to do to remove it?

Turn it the right way - which is anti-clockwise.

Krusty is correct. But when you know this you have not yet completely
solved the problem. The blade has to be rock solid to undo the nylon nut.
To do this jam a short beefy piece of timber (say 70 mm square x about 18 cm
long between the end of the blade and the inside of the plastic frame of the
mower to prevent the blade turning anti-clockwise. Then use an adjustable
spanner to to turn the nut anti-clockwise. Job done.
