A wheel mounted string trimmer having a wheel support with a pair of wheels mounted on opposite sides thereof and handle bars extending rearwardly from the support. An elongated tube housing a drive shaft, is adjustably fastened to the wheel support to extend forwardly to a string trimmer head which is coupled to the drive shaft by a gear transmission whose housing is rotatably mounted on the front end of the tube. The trimmer head has a shield fixed to the transmission housing to be adjustable therewith about the tube housing. A yoke bracket is fixed to the shield while being mounted about the tube housing to be adjustable about the axis of the latter to orient the shield and head in the desired position for trimming. A gasoline engine, mounted to the rear of the tube housing, drives the head through the drive shaft and transmission.
A wheel mounted string trimmer comprising in combination a wheel support having at least one travel wheel mounted on said wheel support for rotation over a ground surface, an elongated tubular drive shaft housing extending forwardly of said wheel support and having opposite front and rear end portions, means fixing said drive shaft housing to said wheel support to be movable with said wheel support as a unit, a string trimmer head located at the front end portion of said drive shaft housing, a power source located at the rear end portion of said drive shaft housing, drive means operatively connected to and between said power source and said trimmer head to drive the trimmer head, said drive means including a drive shaft in said drive shaft housing and a transmission having a housing mounted for adjustable rotational movement about the front end portion of said drive shaft housing, a shield mounted to the drive transmission housing to be rotatable with the transmission housing and trimmer head relative to and about said drive shaft housing, and means connected to the shield for releasably securing the shield head and transmission housing in adjusted position relative to said drive shaft housing.
A wheel mounted cutter comprising in combination a wheel support including at least one wheel mounted on said wheel support for rotation over a ground surface, a drive shaft housing extending forwardly of said wheel support and having a front end portion, means mounting said drive shaft housing to said wheel support to be movable with said wheel support as a unit, a transmission housing including a transmission located at the front end portion of said drive shaft housing for driving a cutter connected to the transmission, drive means operatively connected to said transmission to drive the same, said drive means including a drive shaft in said drive shaft housing and means mounting the transmission housing for adjustable rotational movement relative to and about the front end portion of said drive shaft housing, and means for releasably securing the transmission housing in angularly adjusted position relative to said drive shaft housing.
A wheel mounted cutter comprising in combination a wheel support including a yoke having opposite sides and a central portion, an axle mounted in opposite sides of the yoke below the central portion, a pair of travel wheels mounted on opposite ends of said axle, a cutter assembly including a drive shaft and a cutter member mounted at one end of the drive shaft forwardly of the yoke, and means mounting the shaft for adjustable movement to either side of said yoke about a generally vertical axis, said means including a pair of locking members respectively fixed relative to the shaft and means releasably securing said locking members relative to said central portion of said yoke.
A wheel mounted cuter comprising in combination a wheel support including at least one wheel mounted on said wheel support for rotation over a ground surface, a drive shaft housing extending forwardly of said wheel support and having a front end portion, means mounting said drive shaft housing to said wheel support to be movable with said wheel support as a unit, a cutter housing located at the front end portion of said drive shaft housing for mounting a cutter to the drive shaft housing drive means for operating the cutter including a drive shaft in said drive shaft housing, means mounting the cutter housing for adjustable rotational movement relative to and about the front end portion of said drive shaft housing, and means for releasably securing the cutter housing in angularly adjusted position relative to said drive shaft housing.
A wheel mounted cutter comprising in combination a wheel support including a yoke have opposite sides and a central portion, a pair of travel wheels mounted on said support at said sides thereof, a cutter assembly including a drive shaft and a cutter member mounted at one end of the drive shaft forwardly of the yoke, and means mounting the drive shaft to said central portion for adjustable movement to either side of said yoke about a generally vertical axis, said means including a drive shaft housing receiving the drive shaft, and means releasably securing said housing relative to said central portion of said yoke.
