Skid-steer type power unit engageable with an implement using an attachment assembly including an attachment frame and a hitch. An arcuate frame member is located forwardly of the attachment frame and is engaged therewith in such a way that the frame member pivots about a vertical axis located forwardly of the frame member and generally centrally positioned relative to the attachment frame. The frame member pivots in response to actuation of a hydraulic cylinder. The power unit includes a system for transferring weight of the implement rearwardly onto the power unit. A belt-drive power-take off system on the power unit powers the implement's operation. An underbelly drop spreader is located between the front and rear wheels of the power unit and a brine delivery system distributes brine from nozzles located rearwardly of the rear wheels. A unique control panel permits operation of all systems on the power unit and implement.

An aerodrome maintenance apparatus for monitoring runway and taxiway conditions and remotely reporting the status of the runway or taxiway. The apparatus comprises a drive unit operable to provide self-controlled rolling movement of the apparatus along a surface of a runway or taxiway of the aerodrome, a detection unit comprising one or more sensors configured to detect one or more parameters of the surface, and a communications unit comprising a transceiver arranged to transfer data derived from the detection unit from the apparatus to a remote server. The apparatus is arranged, in use, to move along the surface and transfer data representative of one or more parameters of the surface to a remote server.
