On the 2120 I use, if the box scraper is not on, forget it. The rear end is off the ground, loaded ags and all. The loader is decently strong, my concern is that the bucket is actually a bit to big for the size of the tractor. It's great for light material, but heaped, the hydraulics get slower then they already are and you need to always carry the load low. Since we use this tractor at an orchard, the rollbar is off so using the loader brings on a new sense of urgency when the rear end gets light.
