Bosch Cordless Lawn Mower ROTAK18V2-43 (43cm, Without Battery)

What battery capacity is recommended for this mower?

The ROTAK18V2-43 works with all Bosch Power for All 18V batteries. For optimal performance, 4.0Ah batteries provide approximately 45 minutes of continuous cutting time. Larger 6.0Ah or 8.0Ah batteries extend runtime further. Two 4.0Ah batteries typically handle most medium to large lawns in a single session.

How does the mulching function work?

The included mulch plug blocks the rear discharge chute, forcing grass clippings to be cut multiple times by the blade. This creates fine clippings that decompose quickly, returning nutrients to the soil. The mulching function works best with dry grass and regular cutting schedules to prevent clogging.

Can this mower handle long or wet grass effectively?

The brushless motor provides sufficient power for longer grass, but performance is optimal with regular cutting schedules. Wet grass can cause clogging in the cutting deck and grass bag. For best results, mow when grass is dry and avoid cutting more than one-third of the grass height in a single session.

What is the actual weight of this mower?

The mower weighs approximately 15kg without batteries installed. Adding two 4.0Ah batteries increases the total weight to around 17kg. Despite this weight, the large wheels and ergonomic design make it manageable for most users, with several reviewers noting good manoeuvrability.

How does the grass bag indicator work?

The mower features a grass bag full indicator that alerts you when the 50-litre capacity is reached. This prevents overfilling and maintains optimal cutting performance. The magnetic attachment system allows quick bag removal and emptying without interrupting your mowing rhythm.

Is the cutting height adjustment easy to use?

Yes, a single lever adjusts all four wheels simultaneously across seven height positions from 30mm to 75mm. The lever is positioned on the side of the deck for easy access during operation. No tools are required, making height changes quick and convenient mid-mow.

How compact is the storage footprint?

The handle folds down completely, allowing the mower to stand vertically on its rear bumper. This reduces the storage footprint significantly compared to traditional mowers. The compact storage position measures approximately 60cm in height, making it suitable for most garage and shed spaces.

What maintenance does this mower require?

The brushless motor requires minimal maintenance compared to petrol alternatives. Regular cleaning of the cutting deck prevents grass buildup, whilst the blade should be sharpened annually for optimal performance. The fabric grass bag can be washed when needed and battery terminals should be kept clean and dry.
