Supplemental data for "An Automated On-the-Go Unloading System Reduces Harvest Operator Stress Relative to Manual Operation"

**Dataset information**

-machine-operator_usage.csv

This file contains the data for the machine-operator usage for July, October, and November for three grain cart tractors. This is the data for Figure 3.

The table includes the following variables for machine-powered days:

day, machine ID, time spent driving at slow speed, time at medium speed, time at fast speed, time machine was powered before harvesting, time machine was powered after harvesting, time stationary during harvesting, total time machine was powered, total distance travelled

**Dataset information**

-stress_combine.csv

-stress_grain_cart.csv

These files contain the stress rate and other unloading data for each on-the-go unload event (the ones that qualified for stress analysis). This the data for Figures 4–9.

These tables include the following variables for unload events:

unload ID, state, crop, unload event start time, unload event end time, automation type, duration auger on, automation time percentage, number of stressful events, number of invalid wristband data points, mean tractor speed, mean combine speed, stress rate, combine operator experience, stress rate manual mean, subject-normalized stress rate, combine operator ID, grain cart operator experience, grain cart operator ID

**Dataset information**

-XTEt_XTEc.csv

This file contains cross-track error (XTE) standard deviation (SD) data from each on-the-go unload event that was used to evaluate steering performance. This is the data for Figure 10.

The table includes the following variables for unload events:

unload ID, state, crop, unload event start time, unload event end time, automation type, duration auger on, automation time percentage, mean tractor speed, mean combine speed, XTE SD combine, XTE SD tractor
