The Propeller Untei (プロペラ雲梯) is a Third Stage obstacle, introduced in SASUKE 1 as the second obstacle.

Competitors must across a series of 3 horizontal, slowly-spinning bars, which were anchored to the top of the course. All of the bars moved clockwise and at the same speed.

After Akiyama Kazuhiko's kanzenseiha in SASUKE 4, it became the first obstacle in the Third Stage. Competitors had great success in this obstacle despite the torque was slower resulting in competitors taking longer time to transit from each bars, as the only competitor to fail was James Okada in SASUKE 7.

In SASUKE 9, it was replaced by the Rumbling Dice.

KUNOICHI Appearances

Propeller Untei, KUNOICHI 10

After 15 years hiatus since SASUKE 9, the Propeller Untei returned. This time, the obstacle appeared as the first obstacle in the BLACK Stage (Third Stage) from KUNOICHI 10 onward. Although several competitors showed struggles while attempting this obstacle, due to the torque was less which resulted in frequent halt from the bars, all competitors could complete it so far.

A variation of the Propeller Untei (called as the Propeller Bar) appeared as the fifth obstacle in Stage Three on American Ninja Warrior 6, replacing the Bungee Rope Climb from the past two American Ninja Warrior seasons.

However, unlike in SASUKE/KUNOICHI, there was only one wooden propeller (8 feet in length) that spun freely. Competitors must jump from the trampoline and grab the propeller, spun around, and then grabbed the rope, transitioning to the Hang Climb. Joe Moravsky was the only one to attempt it and had completed it.

During USA vs. The World, all competitors who attempted the obstacle could complete it.

On American Ninja Warrior 7, the obstacle was replaced by the Pole Grasper. However, starting on that season until American Ninja Warrior 10, it was moved to the new position and stage, as the second obstacle in Stage One, replacing the Giant Cycle/Giant Ring from the past two American Ninja Warrior seasons. This time, after grabbing the rope, competitors must swing it to reach the landing platform.

This version of the Propeller Bar had taken out a lot of top competitors, including Sam Sann (in a similar fashion to his Giant Cycle/Giant Ring fall on American Ninja Warrior 5 and American Ninja Warrior 6), Karsten Williams, Adam Arnold, Kacy Catanzaro (who fell on it twice in a row on American Ninja Warrior 7 and American Ninja Warrior 8, before being able to complete it on her final American Ninja Warrior appearance on American Ninja Warrior 9), Michelle Warnky, Lance Pekus, and Brian Kretsch.

On American Ninja Warrior 11, the obstacle was replaced by the Spin Your Wheels.
