Tip For S220 Model
The lifting capacities were calculated with a Standard
Configuration Machine (machine equipped with a pin-on
interface and no attachment). The weight of the
attachment, hydraulic clamp (if equipped) and different
interface must be subtracted from the lift capacity, to
obtain the actual lift capacity.
For bucket weights, see your Bobcat dealer. For attachment weights, see the attachment Operation &
Maintenance Manual.
