Agricultural Technology & Mechanics Nebraska Career Development Event Handbook and Rules for 2018-2020 1. PURPOSE Agricultural Technology and Mechanical systems is comprised of strong technical content and complimented by the development of practical, hands-on skills. The subject matter areas and skill development practices have been grouped into three ‘systems’ areas, so named because of the complex interaction and synergistic processes common to agriculture. The term ‘system’ is used to emphasize the interactive relationship between each area of agricultural technology and mechanical systems. These three systems are: Small Gas Engines or Hydraulic/Pneumatic, Electrical, and Machines.
