Door of the Tractor

As the audio begins, the clear, unmistakable sound of a metal door creaking open fills the air. It's the door of a tractor - a heavy, aged door that's seen better days. Its rusty hinges groan in protest, producing a long, high-pitched squeal that is as grating as it is distinctive. The door's metallic clank echoes around, a testament to its hardy, weathered construction. The tractor itself is implied to be just as sturdy, a trusty machine that's been through countless hours of hard labor. The sound of the opening door is gritty, raw, and real, painting a vivid picture of a rustic, rural setting.
