I agree. I think its just a marketing thing though. How much of that loader capacity is actually usable?
You could put a loader rated for 5000# lift on one of these tractors.....doesnt mean you are ever gonna be able to lift that much. But they do it for people that only compare paper specs.
I used to have a
L3400....which is same basic machine as the 2501. And even with its "weak" loader.....It still took loaded tires and either 1000# in a weight box or 700 pound implement (that sticks back farther) just to keep the rear end on the ground. So any additional loader capacity cannot be utilized unless you add alot more weight than that out back.
Heck, I have a MX, which is 1000 pounds heavier than the branson and 10" longer wheel base. And the branson loader is rated to lift just as much

. I have loaded tires (~700lbs), cast wheel weights (~600lbs), and unless I have something 1000 pounds or heavier out back, the loader will lift the rear.
Couldnt imagine this loader on a 10" shorter machine thats 1000# lighter. But hey.....it looks better on paper right? To but big cylinders on a loader even though it cannot utilize the extra capacity and just makes it operate slower.
