I'm waiting for that one, too.
A PT-425 is rated at 800 lbs. Unlike most ratings of this type, the machine can actually lift more than 800 lbs. It just can't balance it without a counterweight on the rear, especially if the wheel is cranked over.
I've never driven an 1850, but I doubt that it could lift enough to raise the rear wheels off the ground, unless its hydraulics could vastly overpower the loader mechanics, in which case things would break frequently. Hmmmm, wait, Woodland Farms breaks things a lot . . . . . .
