A modular landscaper uses oversized wheels to generate torque for turning one or more of several interchangeable modular landscape maintenance attachments. The landscaper provides a handle configured in relationship to the landscaper frame to allow an adult to normally walk behind the landscaper while applying a forward force by pushing on the handle that results in the wheels of the landscaper rolling along a landscape maintenance surface and generating torque that is transferred through a drive train to the one or more attached landscaping maintenance attachments. A drive train uses the rotational energy of the wheels to increase the operator pushing force to operate the maintenance attachment. Interchangeable attachments facilitate using the landscaper for a wide variety of landscaping maintenance tasks.
