The half-tonne concrete lid of a submersible pump slipped and pinned New Zealand farmer Ken Miller in a stream at the bottom of a gully.
Miller was convinced he'd either lose his arm or drown.
"It was coming down harder on my arm, it was all numb," Miller told The Dominion Post.
"I didn't have a knife, so I couldn't cut my arm off. I did think about that, but you would need a hell of a knife to cut through that bone.
"I didn't really panic – I was trying to work out when I was going to be found, later that night or the next morning."
Unable to free himself – and sinking further into the mud – Miller reached for his phone.
He told The Dominion Post that he usually doesn't carry his phone with him, but he was expecting a call from the pump service.
With limited cell reception, none of his emergency called connected.
Even though the screen was damp, making it hard to text anything legible, Miller managed to text the words "help," "stuck" and "rivrr" to his friend Sandra Duthie.
