Yes, the LA524 is rated at "only" 1131 to full height at the pins. However, it is much stronger at ground level (see below). Given the ~2000 pound break out (depending on how far from the pins), I would want to error on the high side on the ballast. ~2000 pounds on the loader of a light tractor is no joke and can cause you to get quite tippy even when the loader is low. I would want to get closer to 1000 pounds on that 3 pt for max lifts near ground level.
