Tips on lawn care
Here are some tips to help you keep your lawn looking healthy and ensure uniform growth.
Mowing
A lawn is made up of various different types of grass. If you mow your lawn frequently, those types of grass which form strong roots and a firm turf surface will grow better. If you only rarely cut the grass, you will encourage the development of high-growing types of grass and other weeds, such as clover and daisies. The normal height of a lawn is approx. 4–5 cm. Only 1/3 of the total height should be mown; therefore cut 7–8 cm long grass to normal height. Preferably do not cut the lawn shorter than 4 cm, otherwise the turf will be damaged in a dry period. If the grass has grown particularly high (e.g. during a holiday period), cut it back to its normal height in stages. When mowing, always overlap the mown swaths slightly.
Mulching (using the accessories)
During mowing the grass is cut into small pieces (approx. 1 cm) and is left on the ground. A lot of the nutrients in the cut grass are retained for the benefit of the lawn. For the best possible result the grass must always be kept short, see also section ”Mowing”. Observe the following mulching instructions: – Do not mow wet grass. – Never mow more than 2 cm. – Drive slowly. – Use the maximum engine speed. – Regularly clean the cutter deck.
