I presently have the L3130 with the la 723 loader and want to upgrade to either the l3940 or l4240. The l3940 only comes with the la724 loader. My question is . The la854 specs show a lot more lifting capacity. Does it pan out in reality or will I not notice the difference from the la724. Any of you out there that have gone form one to the other and what is your assessment.
