The bristle lawn brush cartridge is used for collecting light debris, putting a stripe in a dry lawn without mowing and incorporating a light top dressing into the sward. The brush is perfect for collecting ‘worm casts‘ that are left by earthworms that live in the root zone of the soil. This accessory effectively disperses and removes these worm casts and other debris such as fallen leaves, twigs, grass clippings or litter and deposits it into the grass box. It’s also great for removing dew from the lawn that can cause fungal diseases.

Setting The Height

Make sure to set the brush height correctly in relation to the height of your lawn so that the optimal amount of debris is picked up. Your bristles should be just flicking the top of the debris. Make sure you don't sent your brush too low as it will damage your bristles and also kill your battery life quickly. The HoC gauge on a mower is calibrated to the cylinder diameter and other cultivation cartridges with an approximate diameter of 132mm to 142mm whereas the brush has a larger diameter of approximate 152mm. Giving the difference in diameter if the brush is set to 10mm HoC the actual working distance will be approximately 10mm lower than the HoC reading. For example if your HOC is 20mm your brush is set at 10mm.

The Lawn Brush is also useful for covering renovating seed material or to work in top dressing.
