For heaven's say, WHY? We mow a lawn like that in less than 20 minutes
with a mains electric rotary.

Do you use an extension lead? Then that is why you should be using a petrol
unit.

Before you answer no, electric mowers do not come with anything like a 100Ft
or cable, so if you answer no, then your garden isn't that length.
