Crush becomes a problem for us in Canola and Lentils during desiccation; which is a chemical application at the end of the season right before havest. As the name implies, desiccation takes a crop which might have variations in "greenness"/maturity and kills it all down to a consistent state for harvest.

At this point in the crops life, the canopy is quite filled out, and a large portion of it is already dry. By driving through the feild at this time you knock the seed from the pod onto the ground, where it is impossible to harvest. Thus it is better to do desiccation from the air.
