Remember, the size of a tennis court is around 260m², this should give you an idea as to how much more the AdvancedRotak 36-660 will cover on a single charge.

With regards to the safety key, it really doesn’t matter whether you leave it in or not whilst in storage, its primary purpose is safety and to stop the mower being started by children etc. The 750 does naturally become heavier as the grass box fills but I never had any issues manoeuvring the mower around the lawn. With a medium-to-large lawn, which is heavily strewn with leaves, you may need to empty the box more than once.

Which one is best for you depends on the size of your lawn, with the 650 designed for lawns up to 650 m² in size and the 750 for lawns up to 750 m² in size. The 750 mower does a fantastic job of compacting the cuttings into this very large grass box meaning less trips to the compost for emptying.
