Added Boom Angle to the chart, since the angle indicator is visible from the seat.
Chained the crane scale to the convenient stump and zeroed it:
With the boom extended all the way out and up at 20 degrees, it took 2,541 pounds added to the 1,168 pound grapple, to raise the rear wheels up.
With the boom at 40 degrees, it took a total of 4,728 pounds to raise the rear wheels up.
With the boom at 50 degrees, it took a total of 5,994 pounds to raise the rear wheels up.
Note the rear end is airborne. :thumbsup:
With the boom at 65 degrees which is max, I curled the grapple to pull up on the chain, the scale went over 5,000 pounds, showed Over Flow, the rear wheels stayed on the ground and just before I snapped the picture of the scale readout the chain broke.
