Do need to torque the blades of my topper?

[Fergulator]

I want to take the blade of my topper becasue they are so blunt, but before i do that, I'd like to know if it needs a torque. I have a milwaukee impact wrench which is meant to go up to 340nm. Is this enough? too little? too much? needs torqueing with a torque wrench?

Many thanks, I'm not too sure what the model is but its says "cutlet" on the back

It will be a port agric cutlass.
If you want to do it properly you should replace the mounting bolts then obtain the correct torque figure from manufacturer.
But in reality just get new bolts and do them right as you can.

would they be something like an m20/24 that tighten onto a boss through the free swinging blade?

Think thats a Port Agri
i ve a double rotor and i grind the blades to sharpen them
But have replaced them when they ve hit a few stones
No torque required, just tighten the locknuts, and leave movement for the swing when you hit a stone
