STIHL HL-KM 50cm Hedge Trimmer (4243 740 5003)
The STIHL HL-KM 50cm hedge trimmer attachment (4243 740 5003) adds adjustable, long-reach hedge-cutting capability to a compatible STIHL Kombi power unit. Its 50cm cutter bar adjusts in stages through a 145Ā° range, helping you find a practical working angle for hedge sides, tops and low growth.
Use it for hedge maintenance around the home or demanding garden work on larger properties. The long-reach design helps with taller hedges, while the adjustable head also suits cutting close to the ground. After the job, fold the cutter bar for more compact transport and storage.
