400 to 500 lbs depending where the load is centered. At max height, this load will be squirrelly as the loader will be flexing and the tires will be flexing on a narrow base (about 44"). I've had my bucket on my 2200 heaping w/ wet dirt and I could barely 'curl' it, but that's a pretty heavy load. I dumped such a load in a big contractor wheelbarrow a big ol boy was holding and he couldn't begin to handle it. Waist high, this heavy a load is e z to handle.
