The machine is big enough for any lawn, the engine is powerful enough to take any strain and it is easy to push and empty. I went over the lawn on the highest setting and again on each of the remaining settings until I was at the lowest where the blades cut furrows into the lawn. Ever since being founded in the 1800s, Bosch has been a leader in the tools trade with its innovative product designs.

However, the first ‘treatment’ is bound to be the worst particularly if your lawn is in a poor state. However, be warned, there may be some baled patches once you go around your grass as it will pick up its fair share of dead grass (thatch) that you may not have realised would happen but this will row back.

I then do a treatment of lawn, weed and feed plus moss killer, which I talk about in this guide too.

It is a more compact unit and costs less than the Bosch and the slightly larger wheels at the front may make it a little easier on the uneven surfaces. The higher settings are used to collect surface debris, such as leaves, while the lower settings scarify thatch and moss and, inevitably, some grass.Two passes, the first as parallel lines along the length of the lawn and the second pass, following the same principle, but at right angles to the first pass. Yes the Bosch build quality is superior but for such light use the Flymo is quite a bit cheaper and has 6 height adjustments (-0. The Bosch AVR 1100 has a very impressive 50 litre grass box, now this may not sound large, but when compared the Flymo at just 34 litres you will see this is large for a lawn rake of this size.

Now the above may sound trivial and are common to most lawn rakes but should be taken into consideration anyway. Place the upper part of the grass catcher into the rear groove of the lower part and join the two halves. Performance: the combination of 1100 watt Powerdrive motor and “Jet-Collect System” enables fast verticutting without tool blockage.I have also been lucky enough to try other models, so don’t forget to check out my best scarifier reviews guide here, and if you think petrol is for you (you have a larger lawn or perhaps no plug socket, then check out my petrol scarifier review in this guide. The integrated collection box does make the Flymo smaller for storage but the comprise is the smaller collection box and the need to empty more often. The Jet Collect system is clearly a feature that makes a real difference to the job in hand, the collection box capacity is increased and the ability to collect the debris is improved – Great job Bosch! Remember this rake has a large 50 litre collection box so less stops to empty helps to get the job done quicker. Motor power: The AVR 1100 has a more powerful motor at 1100 watts, while the ALR 900 has a 900-watt motor.

The Bosch AVR Electric Lawn verticutter is very proficient at raking and scarifying varying lengths and thickness for such a small and compact verticutter, the only sight disadvantage is you only have 4 different height settings. There is no level indicator or vision window on the Bosch AVR 1100 so it can be little difficult to know when the collection box is full. It has four height settings that are easily selected by adjusting the height of the front wheels with the two levers. After the heavy rains in January, the lawn was covered in lots of moss and needed some TLC so rather than doing it by hand, I bought this machine (chose this over the AVR 900 as more power and no small metal pieces to replace).However, if your lawn has more deep-rooted weeds or you require a deeper cut, perhaps with a view to over or reseeding, then you will need the AVR 1100. For a 300m2 you could also consider the more powerful VonHaus 2 in 1 Lawn Scarifier (1800 W model) as this allows you to switch drums between tines or blades.
