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. You’ll love the super sharp Leafcollect blade which gives a uniformed neat finish and also effortlessly collects, shreds and distributes leaves from your lawn into the collection bag for easy disposal. This makes the Bosch Advanced Rotak 650 extremely useful in any season. And those tiresome leaves that fall all over your lawn in the Autumn won’t be a problem any more! This AdvancedRotak 36-660 is the bigger brother of the Bosch UniversalRotak 36-560 and these two new mowers from Bosch are almost identical. For this reason, I am not going to write a full review of this larger Bosch cordless mower, but direct you to the full review of the Bosch UniversalRotak 36-560 here. But before you go – you need to know what the differences are between these two mowers so you get the one that is best suited to you and your lawn. With the Bosch AdvancedRotak 750 you get an integrated height adjustment feature that is so good and makes adjusting the height a breeze. The handle is located centrally and there is a perfectly placed button that is pressed to either raise or lower the mower. Again see my video above to see just how good this feature is. Has a 50 litre foldable grass box that folds flat for easy storage and prevents overfilling via fill indicator

A cool addition to this electric motor is the ProSilence function. This reduces the noise output of the AdvancedRotak 650, making it much quieter than many smaller sized lawn mowers. This is a great feature for those wary about making too much noise when cutting the grass. Cutting Width Offers excellent results and quiet mowing with acoustically enhanced design and ProSilence feature. AdvancedRotak offers 7 cutting heights, ranging from 25 to 80mm, with simple button operation. LeafCollect blade cuts grass and can also be used to collect leaves.Because everything only involves slight pushing and pulling rather than major screwing and lifting, the design seems well suited to anyone with reduced mobility or arthritis. Plus, it’s handy that the cutting height adjuster has an indicator that tells you what setting you’re moving it to. Best of all, the height is so easy to adjust. Many mowers have awkward placed levers or levers that are stiff to move, but this isn’t a problem with the AdvancedRotak 650. The blade adjustment is integrated into the central cutting and you just push a button to get the desired blade height – so much easier than most other lawn mowers! Ergomonics Hi Joe, the difference is that the 36-660 has 2 x 2.0Ah batteries and the 36-650 has 1 x 4.0Ah battery that covers a slightly smaller area. Remember that the number i.e. the 660 refers to the square meter coverage. The Bosch AdvancedRotak 750 comes with a full 3 year manufacturers warranty covering both faulty materials and faulty workmanship, it does not cover general wear and tear or damage, blades and other consumables.

Their expertise is very apparent in their present range of lawn mowers and garden tools as it includes products, which no other garden machinery manufacturer produces. The Rotak electric and cordless lawn mowers demonstrate the company's willingness to innovate with features like grass combs that enable you to mow right up to the lawn's edge and rechargeable lithium-ion batteries that have virtually no weakened performance after extended use.While many electric lawn mowers struggle with long and wet grass, the AdvancedRotak 650 has ample power to handle overgrown lawns, making it a good choice for bigger lawns that are left to grow during the seasons.
