Last year, Iowa State University's ¼ scale tractor pull team had its high hopes dashed when they finished much lower than expected in their annual competition. With this year's entry, named Cy's Revenge, the ISU Power Pullers are set to roar back to the top, where they believe they belong.
"We need to go into the competition and get our name back, as a quality team, and get back to a top five spot," says Kent Thoreson, a junior in ag engineering and president-elect of the Power Puller's club. "That is where we need to be."
Thoreson and the rest of the Power Pullers will see how they measure up at the 14th Annual International ¼ Scale Tractor Student Design Competition, to be held June 2 to 5 in Peoria, Ill. The competition is sponsored by the American Society for Agricultural and Biological Engineers, a professional organization dedicated to engineering for agricultural, food, and biological systems.
ISU team faces competition from all over the U.S. and Canada
While the competition attracts teams from all over the United States and Canada, this year will be especially difficult for the ISU club with only one returning senior.
"It has been a challenging year for us because we are all young and hadn't had any design experience," says Thoreson. "So we sort of just jumped into it."
With so little team experience, the ISU Power Pullers were not simply making improvements on a previous tractor design, they were really starting over.
"We pretty much had to build it from scratch, so that's what we did," he says.
Complicating this year's competition even more were the new rules about weight (there is a new, lower limit of 800 lbs. total) and the number of engines (one 31-horsepower, or two 16-horsepower only).
Pulling is a major criterion for judging, but other aspects of the tractors are also scrutinized. Teams are judged on a written design report prior to the competition, an oral presentation, tractor maneuverability and overall design which includes manufacturability, serviceability, safety, ergonomics and loudness.
Teams are judged on other things in addition to pulling success
Cy's Revenge is being presented as a utility tractor for a small hobby farmer, so a lot of effort was concentrated on ease of use, design of the operator station, and a designing a power-shift drivetrain that allows the operator to shift from high gear to low gear to while the tractor is moving.
The judging is done by industry professionals from major corporations. Many of the Power Pullers are able to interact with and get job leads from representatives of the companies. For right now, however, Thoreson and the Power Pullers are focusing on the competition and getting Cy's Revenge to pull them to a top finish.
"Hopefully, we'll score well on the pulls," says Thoreson. "I think we have a really good design for that. You've got to make sure you've got a tractor that can pull. If it doesn't pull, you don't win competitions."
This year's Power Puller president is Peter Horne, a junior in ag engineering. The Power Pullers rely on corporate funding to enable the team to compete. He says,
"Without the strong support provided by our sponsors, it would be impossible for our team to compete in this important competition. The Cyclone Pullers really appreciate the great support they have received from their many sponsors."
