## Narrative

While engaging the bank to get a dipper full of material the teeth encountered a hard bottom jarring the shovel. This caused the foot latch on the operator seat to release, and the operator seat to slide back and hit the stops. When the seat hit the stops the operator aggravated an old back injury.
