This genuine Toro OEM trimmer mount kit is designed for GrandStand stand-on mowers and allows the operator to mount a string trimmer directly on the mower — enabling simultaneous mowing and trimming in a single pass. This is particularly valuable for commercial operators looking to improve crew efficiency and reduce the number of passes required on a property. A popular at-purchase accessory for GrandStand owners doing production-oriented mowing work. Verify your model and serial number before ordering.
