摘要：
The invention is concerned with a string reel (1) for being mounted on a cutting head of a string trimmer in a rotatable manner in mowing operation.The string reel (1) is constructed as an exchangeable wearing part, onto which a number of mowing string strands (2) is wound up, for example two mowing string strands (2), so that in mowing operation each free thread end is pulled radially outwards by centrifugal force and the piece of thread pulled outwards by the rotary movement in mowing operation and located at the free thread end can knock off plant stalks. The mowing string strands (2) have a greater length than the respective thread piece pulled outwards in mowing operation at the free thread end, so that the number of mowing string strands (2) can be pulled out at the free thread end after wear of the thread piece. At least one of the number of mowing string strands (2) has a different appearance in a normal consumption section (3) extending starting from the free end of the respective mowing string strand than in a reserve section (5) which can only subsequently be pulled out and is located closer to the connection point to the string reel (1), wherein the at least one of the number of mowing string strands (2) in a warning section (4) situated between its normal consumption section (3) and its reserve section (5) has a different appearance than in its normal consumption section (3) and in its reserve section (5).
