The AEG 58V Line Trimmer features a well-balanced, ergonomic design for easy use and reduced operator-fatigue with included shoulder harness. The 2-Speed switch and variable speed trigger provide more control to the operator and better match the tool to the application. The unit features an outer rotor brushless motor, which provides outstanding performance and long run-times. The aluminium split-shaft design allows the user to detach the boom for compact storage or attachment capability. The low profile easy-wind, bump feed head allows for quick and easy trimming line replenishment. A great tool for large jobs, requiring all the power of petrol, with the convenience of cordless operation.
