Large lawn petrol, but for a small lawn Bosch is all you need, it’s lightweight, cuts amazing close to the edge of the mower and the finish is impressive, ok it feels lightweight and a bit flimsy, but so far it’s not let me down, if you don’t like cables the rechargeable one is good. Invest in a spare battery, not cheap!
I swapped from a flymo five years ago and it was the best decision I ever made.
Petrol wise if you don’t want to spend Honda prices, have a look at the mountfield range with the Honda engine, we used to use them at work (x parkie) and would easily run 8 hours and lighter to throw about than the Honda’s.
