Buckeye Pullers is a student organization at The Ohio State University that designs and builds a 1/4 scale tractor each year for the ASABE annual competition. The 2013 tractor, Brutus 201, features two-wheel-drive, a CVT transmission, and one 31-horsepower Briggs and Stratton engine. At the 2013-2014 contest Brutus placed 3rd out of 27 universities from the United States and Canada.
The International 1/4 Scale Tractor Student Design Competition is unique among student engineering-design contests in that it provides a realistic "360-degree" workplace experience. Teams of students are given a 31 hp Briggs & Stratton engine and a set of Titan tires. The design of their tractor is up to them. A panel of industry experts then judge each design for innovation, manufacturability, serviceability, maneuverability, safety, sound level, and ergonomics. Teams also submit a written design report in advance of the competition, and on-site, they must "sell" their design, in a formal presentation to industry experts playing the role of a corporate management team. Finally, machines are put to the test in a performance demonstration comprising four tractor pulls.
Through involvement in the competition, students gain practical experience in the design of drive train systems, tractor performance, manufacturing processes, analysis of tractive forces, weight transfer and strength of materials. In addition, they will also develop skills in communication, leadership, teamwork, fundraising and test & development.
