Here's some math fun.
To determine the CG, the jack is the reference and the ball is an additional 2 feet from the reference. If weight * arm = moment, then the arm can be determined by comparing the moment for both measurements on the same load with X being the arm or length the jack is forward of the CG.
950 * X = 750 * (X+2)
If this kind of thing hurt your head as it does mine go to Mathway: Algebra Problem Solver and type in your equation.
The answer is 7.5 putting the cg 7.5 feet behind the jack...not exactly how I'd like to trailer but reasonably reflects the present load of 1200 pounds of tree shear and grapple forward of the axles for storage purposes.
Or did I do something wrong?
