| The trip (RCD) is going because there is a short (or partial short)
between live or neutral and earth. I think most lawnmowers are two wires
only (no earth), so the problem is mostly likely in the plug. Take a look
for dead spiders, water, etc.

housing.

| An RCDshould only trip if there is an imbalance in the current in the
live and neutral leads. This can happen with a leakage path between
the current carrying wires and earth. If the mower has a three wire
cable then it must have a metal frame. The leakage may be due to damp
inside part of the mower (switch or motor) or may be due to damaged
insulation. If the mower has a 2 wire cable then the leakage must be
to the ground (possibly via the blade). Again this might be due to
damp or damaged insulation, but 2 wire equipment ought to be
sufficiently well insulated that this can not happen !

| First, obviuous question - is it the mower or the socket? If you are
using a seldom used socket check the mower in a socket you know is
good. Similarly with any extension leads. Then check connections in the
failing component.
Good luck!

| Thanks for all the replies. I found the problem. The lead from
the motor to the switch on the lawn mower handle had been scratched (probably when
it rubbed against a garden wall) exposing the wiring.
