A tractor hydraulic adaptor, system and process to hydraulically power a hydraulic attachment on a tractor is disclosed. The hydraulic adapter includes a hydraulic intensifier powered by a tractor's power take off shaft to drive a hydraulic attachment coupled to a tractor's front-end loader. The hydraulic intensifier draws at a low-pressure hydraulic fluid and feeds the hydraulic fluid at a higher pressure to the hydraulic attachment.

A rear trailer hostler can be used to move a parked trailer without otherwise disengaging pneumatic brakes thereof. For example, the rear trailer hostler can lift the wheels of the trailer off of the ground, thereby allowing a front hostler to move the trailer without a gladhands connection to the trailer pneumatic lines. Alternatively, the rear trailer hostler can move the trailer independently. For example, the trailer can be parked atop the rear trailer hostler and disconnected from the truck. With the rear trailer hostler supporting the locked wheels and the landing gear, the trailer can be moved without requiring the pneumatic brakes to be disengaged. The rear trailer hostler can also provide one or more safety or convenience features, such as a bridging platform or a safety door stop.
