Everything I do, everything I see, I'm surrounded by these tiny triggers. They're everywhere and they remind me of what I went through, what Jigsaw did to me.

The Lawnmower Trap is a trap from the Saw franchise, appearing in Saw 3D.

Design and Function

The two victims of this trap were in a large room suspended several feet above the floor and had to cling onto two identical levers hanging from the ceiling across from each other. Both levers were covered with metal barbs, which dug into the hands of the people holding onto them. On the floor below were several upturned lawnmowers. In order for one person to survive, the other had to let go of his or her lever and fall into the rotating blades. (Saw 3D)


Sidney and Alex's Test

Sidney is covered in Alex's blood

The victims tested in this trap were Sidney, a young and insecure woman, and Alex, her abusive boyfriend who had frequently battered her throughout their relationship. After having been subdued and abducted, they found themselves suspended above the numerous lawnmowers and had to cling onto the levers, which slashed their hands. In panic, Sidney begged Alex to save them. He however tried to kick her of her lever without any hesitation. Realizing that she had no other choice, she slapped him in the face, causing him to fall down to his death, where his body was ripped apart by the rotating blades of the lawnmowers. As she was covered in his blood, Sidney began to scream. She had, however, survived and won her game and therefore, was ultimately able to leave unharmed. (Saw 3D)
