She pulled a small lever inside. Click-hiss. The quick coupler released its grip on the standard bucket. Boulder rolled over to the attachment rack, tilted his arms, and Lina eased the coupler’s open jaws over the grapple bucket’s top bar. She raised the lever again. Clunk. The jaws snapped shut, and the locking pin slid home. Fifteen seconds.

In the bustling quarry of Millbrook Valley, the giant wheel loaders worked in shifts, scooping tons of rock and gravel from dawn until dusk. Among them was a seasoned loader named Boulder, a rugged machine with peeling orange paint and a growling diesel heart.
And that’s the story of how a quick coupler turned a slow, stubborn machine into the hero of Millbrook Valley. By the time the manager finished his coffee,
