You maybe thinking of a different tractor. The loaders for BX have always been LA240 and LA243. And from what I understand from a video under Messicks the 2.2 is an approximate for metric convertion at the pivot pin or is it out at center of bucket? Any who they will have to add some power for all the extra beef they added to reinforce for the single cylinder stress in the middle. I have bent my QA a couple of times and would like to convert to twins and keep the stress in line with the arms.
