Features

RM 448 TX

Standard equipment

  • Easy start engine (ReadyStart) Zoom
    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. 


  • Self-propulsion Zoom
    Self-propulsion

    Self-propulsion on the STIHL lawn mowers provides for the desired forward momentum during mowing. This makes working easier, especially on large lawns and inclines.

  • HIGHLIFT BLADE Zoom
    HIGHLIFT BLADE

    FOR AN EFFICIENT AND ACCURATE LAWN CUT. The highlift blade ensures a uniformly short lawn cut as well as optimum filling of the grass collection box. The powerful air flow generated by the blade in the housing raises the grass upright before cutting. The optimised air conduction system then transports the clippings efficiently into the collection box.

  • Fold-open grass catcher box with level indicator Zoom
    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.

  • Easy-running wheels Zoom

    • STIHL Smart Connector Zoom
      STIHL Smart Connector

      The STIHL Smart Connector forms the basis for using all STIHL connected functions. These functions can be used via both the STIHL connected App and the STIHL connect Portal. Once correctly attached to a STIHL power tool or another manufacturer’s power tool, the STIHL Smart Connector records operational hours while the machine is running, stores them and transmits them to your smartphone via Bluetooth as soon as it is within range. The data received in the STIHL connected App is transferred to the STIHL Cloud when there is an internet connection. The data is stored there in compliance with data protection regulations. The STIHL connected App and STIHL connected Portal allow you to access your power tool data at any time. STIHL connected opens up new avenues for professional users to obtain a convenient and transparent overview of their own power tool fleet. At the same time, STIHL connected provides information including operational hours, power tool status including reminders of overdue maintenance, the last known location, and whether or not the power tools are currently nearby. For professional users, this means improved digital fleet management, more efficient processes within companies, and even closer contact with STIHL dealers. Private users can also use the system to keep an eye on their power tools and carry out maintenance at the right time.
