Abstract:
1. A motor-driven work apparatus comprising: a rotatably driven work tool for ground processing and said rotatably driven work tool defining a rotational axis and having a longitudinal end; a drive transmission operatively connected to said work tool and said drive transmission including a lateral bearing region; said lateral bearing region defining an axial direction and facing toward said work tool; said work tool defining a flight circle as said work tool rotates about said rotational axis and said flight circle having a diameter (D said work tool having an end plate connected thereto so as to rotate therewith; said end plate being disposed at said longitudinal end of said work tool so as to lie perpendicular to said rotational axis and said end plate having an outer diameter (D said end plate being configured as a roll-up protective ring for preventing the roll-up of long fibrous material; said roll-up protective ring being configured as a conical disc in at least a component region thereof and said roll-up protective ring extending from an inner diameter (D said roll-up protective ring extending outwardly away from said work tool so as to at least partially overlap said lateral bearing region in said axial direction thereby hindering an accumulation of said long fibrous material at said lateral bearing region.
