US 5,092,112 A · Grass trimmer attachment

Abstract

A wheeled attachment for a grass trimmer includes a mounting bar having a wheel at each end, detachably mountable to the grass trimmer to provide easy control and easy support for the grass trimmer. The detachable bar may be securable by a nut and bolt combination either to a housing or protective cover mounted on the grass cutting head immediately above the grass cutting element, or to an adjustable bar component which is detachably securable to the elongated shaft of the grass trimmer. For easy mounting upon the housing of a grass trimmer, the detachable bar includes adjustment slots for the nut and bolt fasteners so that the fasteners may be easily and quickly adjusted to the size of the housing component. For easy mounting upon the elongated shaft of the grass trimmer, the adjustable bar component includes two or more vertically extending bar members which are adjustably attachable to permit forward or rearward adjustment of the wheeled attachment. Further, the wheels may be preferably positioned on the mounting bar so that the distance between the two wheels on the mounting bar is less than the maximum cutting diameter of the flexible cutting line. Then, also, the wheels may be swivelably mounted.
