Can you give me the torque (in Nm) of fastening the bold of the cutting knife from a Mountfield Mirage 18

There IS a published figure - but just do it up using a 12" lever as tight as you can using unaided muscle power. This will be tight enough, and will ensure that you can get it off again at a later date with no difficulty.

The bolt tends to self-tighten in use.
