ABSTRACT:
A rideable work apparatus having attachments that include a snow plow, a lawn mower and a roto-tiller simultaneously mounted to a frame. Cranks are provided for selectively actuating each of the attachments. A seat for the operator is connected to the cranks by a threaded rod so that when an attachment is actuated by the crank, the crank turns the threaded rod and causes the seat to displace towards the chosen attachment which shifts the center of gravity and achieves better contact between the chosen attachments and the working surface.
