My lawnmower is vibrating so badly it shook the front
Roller off and then it cut out, tripping my sockets.
Thought it was dead but 2 weeks later plugged it in and
Tightened the blades and its working but still severe vibrating. Just over 1 yr old. Scared to use it!. Grass is now up to my ankles. Help!!

Summat is bent or broken off.

Is the blade bent/broken?

Checnk the fan above the blede: is that broken?

Take the blade off, put the nut back and run it like that for a mo. If it still vibrates, it wasn't the blade.

Unplug, turn the mower over and rotate the shaft by hand. Does the shaft look like it is spinning with its end off-centre?

This place has some diagrams which may give a cluse as to how the thing goes together:
