Mulching instructions

General information on mulching

When mulching, the grass clippings are further shredded in the mowing deck housing before being blown back into the lawn, where they decompose.

Benefits:
Finely shredded cuttings decompose readily in the turf and return organic nutrients to the lawn, serving as a natural fertiliser.

Advantage:
Mulching is a time-saving (no emptying of the grass catcher box) and convenient lawn care method.

When is mulching permissible?

It is recommendable only to carry out mulching when the lawn is dry and the grass is not too high.
If the grass is too high, the lawn should be mowed in two stages at different cutting heights.
Never mulch a damp or wet lawn, as the mowing deck can become blocked and the grass clippings are no longer finely shredded.
An inferior cutting performance results.

How often should mulching be performed?

To ensure a perfect, thick lawn, mulch regularly and keep the grass short.

Main growth period:
Spring:
mulch at least twice per week. Summer and autumn: mulch at least once per week.

How should mulching be performed?

The following points must be observed to achieve good mulching results:

Use well sharpened mulching blades:
Only a sharp mulching blade should be used when mulching.
Select the correct cutting height:
The cutting height should be selected so that one third of the grass height is removed and two thirds are left standing.
To ensure that the clippings are cleanly shredded, it is recommended that cutting levels below 3 should not be used when mulching.
Grass too high:
In high grass, the lawn must be mowed in two stages. First stage: The lawn is mowed at a cutting height of5-6. Second stage: 12 to 24 hours following the first stage, mulch the lawn to the desired grass height at right angles to the first mulching direction (see point “2. Selecting correct cutting height”).
Select the correct driving speed:
A low driving speed must always be selected during mulching. This ensures that the grass cuttings are shredded very finely and blown back into the lawn.
Select the correct engine speed:
Always select the maximum engine speed when mulching.
