STIHL RM 443 Lawn Mower

This petrol lawn mower is easy to start and its outstanding cutting performance means that it quickly gets into gear on medium-sized lawns up to approx. 1,200 m². Bespoke cutting pattern thanks to the cutting height adjustment with seven settings and with its convenient folding handlebar can be precisely steered around bushes and trees.

Central cutting height adjustment

The central cutting height adjustment is spring-loaded, which makes it easy to set the desired cutting height in several settings. The current height is indicated by a scale.

Easy start engine (ReadyStart)

Thanks to the ReadyStart technology, the engine of the STIHL petrol lawn mower can be reliably started up with minimal effort both during cold and warm starting.

Highlift blade

The highlift blade gives a precise finish to the lawn and ensures optimal filling of the grass catcher box. The blade creates a strong air current in the housing, which makes the grass stand upright before cutting and efficiently carries the clippings into the catcher box using an integrated and powerful air flow system.

Fold-open grass catcher box with level indicator

The plastic grass catcher box can be easily opened and emptied thanks to its folding mechanism. The current of air produced during mowing blows the clippings into the grass catcher box and ensures a high degree of filling. Thanks to the downward-facing vanes, the air is guided sideways towards the ground, preventing dirt from being thrown up. The level indicator signals the correct time for emptying. The airflow generated by the blade raises the level indicator. When the basket is full, the airflow stops. If the airflow is too low, the level indicator returns to its idle state and this is an indication to empty the catcher box. Optimal airflow is required in order for the level indicator to function fully. External influences such as wet, dense or tall grass, a low cutting height, contamination, etc. may affect the airflow and the performance of the level indicator.
