Tip For S150 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.
