Mission Sta Mission Statement tement  Western Plains Engineering is dedicated to being an innovative leader in the design of large scale agricultural equipment.

Pr Problem Sta oblem Statement tement  It is the goal of Western Plains Engineering to design a large disc for Agri-Industries for primary tillage in western Oklahoma with small transport width and height.

Design Specifica Design Specifications tions  Should be capable of being used as a primary tillage tool (>150 lbs/blade).  Working width of 40 ft or greater.  Flexible frame to follow uneven terrain and terraced fields.  Transport width of less than 19ft.  Transport height of less than 16ft.
