Timo take a look at the attached photos I took in my driveway. Both loaders are of roughly similar capacity. As for how they achieve the space savings, I think it is done by moving thing around, the battery is way in front, the radiator is set low, the fuel tank is held farther back.
As for some earlier discussion about strenght of curved arms, I think much of that may depend on the quality of the metal? Different metals have differnet properties, some are brittle, others not. To my knowledge 4 brands make 1 piece curved arm loaders. Kioti, Montana, Case and New Holland. Deere makes a 2 piece curved arm loader. The Case/New Holland loaders seem to be pretty trouble free. Some complain that they stick out farther than dog-leg loaders but I think that is due to the front axle designs used on C/NH products being set farther forward than on many other machines, especially true for their class 2 machines. It is exagerated even more on their products with the optional SuperSteer axle. Kioti has some reports of stress cracks on both models of their curved arm loaders. Montana is just introducing their curved arm loaders not much time in the field with those, I did look them over at the new dealer that opened up near by. Couldn't tell much from a visual inspection. Deere's 2 piece curved arm loaders seem strong but are not as good in the visibility category as the Case/New Holland loaders. Case/New Holland has some expensive machines but the quality seems to be high and they sure pay attention to ergonomic design.

It is very possible both are correct. A higher grade of steel may be necessary in order to make a curved arm loader stronger? Perhaps that is why some brands have stress crack and some don't but all have impressive capacities?
