Bosch Lawnmower (Woodingdean BN2)

Bosch Rotak 340, 240v mower, good general condition, but runs, slows then cuts out, so needs attention - the brushes are OK, so it probably needs a £3 ball bearing - there's two in there, I replaced one last year and should have done both of them! Lots of these bearings are available online. An easy job for a handy person. We bought another mower now, so no longer needed.
