Abstract
A new Tandem Axle Trailer Pin Leverage Handle System for facilitating the extraction of a tandem axle trailer pin for repositioning of the axles of the tandem axle trailer. The inventive device includes an elongated handle, a first and second plate secured distally apart to the handle, an elongated rod pivotally attached mesial the plates, and a hooked end secured to the rod opposite of the plates for engaging the tandem axle trailer pin. Preferably, there is a first aperture and a second aperture projecting traversely through the plates for allowing selective positioning of the rod for older style trailers or modern style trailers. The end of the handle engages a trailer box simultaneously as the hooked end engages the pin thereby leveraging upon the pin for extracting a frozen or rusted pin.
