1. For lifting capacity including bucket, subtract total weight of bucket and quickhitch from above values. 2. Lifting capacities are based on ISO 10567, that is: 75% of minimum tipping load or 87% of hydraulic lift capacity, whichever is the less. Lifting capacities marked * are based on hydraulic capacity. 3. Lift capacities assume that the machine is on firm, level ground. 4. Lift capacities may be limited by local regulations, please refer to your dealer.
