I was asked if I would like to demonstrate a Thrush agricultural aircraft for potential buyers. I was given a map showing a few close together fields I could use to make spray passes. While finishing up my last pass; I failed to provide enough clearance between the aircraft and a silage wagon parked near the edge of the field. The aircraft's left landing gear; propeller; and some spray components struck the top of the wagon. I returned to ZZZ and landed safely.I attribute this incident to my own sense of invulnerability. Through that; I was careless in planning and executing a clear departure from the field environment. I had about 5 previous spray passes that were clear on the approach and departure and I allowed myself to fall into a rhythm. Unfortunately; that rhythm didn't allow for clearance of the silage wagon.I have come away from this with many thoughts and feelings. The antidote for impulsivity has rang loud and clear; 'It could happen to me.' It DID happen to me; and it could happen to me again! It can also be a lesson to plan each approach and departure from the field before entering the field and stick with the plan.
Agricultural aircraft pilot reported striking ground equipment during a low level spray pass that caused minor damage to the aircraft.
