During takeoff from a grass airstrip behind another agricultural airplane of the same type, the agricultural airplane encountered wake turbulence. The pilot turned the airplane to the left to "try and get out of it." The airplane's left wing and left main landing gear struck the ground, the airplane bounced on its right wing, and landed on its empennage. Subsequently, the airplane came to rest upright in a field. The pilot stated that the accident could have been prevented if he had waited "about one more minute" before taking off.
