Abstract:
A hand held, and hand supported weed trimmer having a belt drive carrying a plurality of cutting blades, said belt drive including pulleys and a belt that is positively engaged by said pulleys to prevent dislodgement and slipping thereof, said weed trimmer comprising:an elongated frame;a handle attached to said elongated frame for hand supporting said frame above ground level;a driving belt disposed upon said elongated frame and carrying a plurality of blades fixedly disposed on a periphery thereof by a removable fastener so that worn or damaged blades can be easily replaced, said plurality of blades each having dual cutting edges, said driving belt being V-shaped and reversible, so that after one cutting edge of said plurality of blades is used, said belt can be reversed, and the unused edge of each of said plurality of blades can be used, whereby the operational life of said driving belt is effectively doubled, and further whereby the V-shape of said driving belt creates a positive belt engagement and prevents the driving belt from slipping and from being dislodged;a pair of spaced-apart pulleys which supports said driving belt for rotation about said elongated frame; anddrive means supported by said elongated frame for driving one of said pair of pulleys in order to rotatively drive said driving belt.
