Can you help me stop my equipment generating radio interference?

This might be slightly off-topic, because the interference generation
problem I need to solve involves long wave radio - please suggest a
better group to post to if you know one.

Problem: Located in the UK, I have a robot mower which is guided by a
perimeter wire laid around the edge of the lawn. Works fine, but
generates RF interference which hits my neighbour's long wave radio
reception (e.g. station Europe 1 at 183 kHz).

For you to get a reasonable answer, a bit more information is needed...

Is there any type of radiation from the guide wire? If so, describe the
signal (frequency, power, analog or digital). If the guide wire is
activated but the mower engine is NOT running, do you get the interference?

Or is the interference coming solely from the mower engine? What type of
motive force is the mower using? Gasoline (petrol) or electric? If
electric, AC or DC? If a DC motor, series wound, shunt wound or
universal? Type of motor speed control (if any); e.g. pulse width
modulation?
