Abstract
The invention provides a combination bed edger and cable layer unit having a common platform and interchangeable cutting wheels and shrouds. The protective shrouds can be attached and removed using knobs, without the need for tools. The cutting blades can be selectively mounted to the drive shaft using bolts on the face of the cutting blades. The unit includes an adjustable handle that can be adjusted to different operating heights, or can be folded over the unit in a storage position. The handle includes a release lever that allows an operator to convert the unit between a transport position and an operating position. The unit includes a chain drive transmission, providing a direct chain drive transmission from the engine shaft to the drive shaft.
