With a Riding Mower String Trimmer Attachment, one can trim around trees, under fences, close to walks, along driveways, etc., even as the mowing operation is going forward. The attachment is mounted to the mower deck and powered by an internal, sealed, electric motor that runs off the mower's battery system. The cutter heads can reportedly be adjusted to any angle between 0º and 90º, allow for lateral movement out from and back to the mower, and can be tension-adjusted for the control of floating action to minimize scalping. Some models feature an automatic feed head that feeds more string as needed.
