lawnmowers - sanli ls-43 & bosch rotak 34-li (Ludlow SY8)

Sanli LS-42 petrol rotary mower and Bosch Rotak 34-LI cordless. Both of these came with the shed on a property I bought recently. The Sanli petrol mower simply doesn't start (probably because battery needs recharging). Comes with a 4-litre can of petrol. The Bosch just needs a replacement battery. Can deliver either by arrangement - they'd be going to the tip otherwise.
