Mobile farm and forestry plant operators
11.8%
ADI · 345th of 433 · 95% interval 0.0–30.8
An AI agent can at least partly carry out 11.8% of the task time of mobile farm and forestry plant operators, and finish 0.0% alone. The barrier that holds most of the rest back is access to the systems the work runs on.
