A relatively small diameter, power transmission driving gear is driven by an edger driven shaft. A relatively large diameter, power receiver gear is driven by the relatively small diameter, power transmission driving gear. A blade assembly drive shaft is connected to the relatively large diameter, power receiver gear. An edger blade assembly is driven by the blade assembly drive shaft. A wheel assembly support is attached to the gear housing, and a wheel assembly is connected to the wheel assembly support. In one embodiment, a height adjustment assembly is provided. In another embodiment, a tilt adjustment assembly is provided. In another embodiment, both a height adjustment assembly and a tilt adjustment assembly are provided.
