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.
• AFNR Courses that align with this CDE include: Power Structure and Technical Systems and in any given themed year the following courses could be included: Agronomy, Large Animal Management, Agribusiness, Environmental Science

Agricultural Technology & Mechanics Page 4 of 37
5. REQUIRED SUPPLIES AND EQUIPMENT Everyone will be given a safety briefing during orientation. Please observe all safety rules, and if you see something that doesn't look safe; let a competition official know. Teams will need to bring the following items with them: (each individual will need all of these things)
• #2 pencils for each person • Safety glasses for each person • Calculator (NO cell phones & NO graphing calculators) • Wire stripper • Flat screwdriver • Phillips screwdriver • Needle nose pliers • Diagonal Cutters • No knives allowed.
6. EVENT SCHEDULE A. Schools will be divided into two groups. Teams should plan to arrive and register not more
than 30 minutes prior to start time and not less than 5 minutes prior to start time. Each section should be completed within 2 hours and 45 minutes, start to finish.
a. Section I, including teams from ½ of the districts will start promptly at 9:30 a.m. b. Section II, including teams from the other ½ of the districts will start promptly at
1:00 p.m. c. Individuals will be divided for the 6 individual activities and rotate every 15 minutes.
(Approximately 15 contestants will begin at each activity table.) d. Every team will be together for one 25-30 minute activity. We will start with the first
5 school numbers (1-5) at the team activity and the rest of the contestants divided among individual areas. Every second rotation will bring the next 5 school numbers (6-10, etc.) to the team activity. After the team activity, students will return to their next individual rotation area from where they left off.
e. The Nebraska Agricultural Technology and Mechanics CDE takes place in the loading dock area inside Pinnacle Bank Arena. Participants should enter in the “Marshaling Door” on the north side of the building. Please be sure to note required and prohibited supplies and equipment before entering the Pinnacle Bank Arena.

7. ANNUAL THEME The annual theme is derived from the National CDE. The theme affects the contest specific machinery/equipment and the team component.
• 2016 - Animal Production Systems • 2017 - Material Handling Systems • 2018 - Processing Systems • 2019 - Plant Production Systems • 2020 - Integrated Pest Management Systems
8. EVENT FORMAT A. Team Activity:
All four team members from each team will work together and be evaluated as a team while solving complex, multi-system agricultural problems. The problem scenario is presented to the team on the day of the event and members utilize the materials and equipment provided to undertake and prepare a solution to the problem. Teams organize themselves, assigning duties and completing tasks together or separately depending on individual skills and abilities. Each team receives a maximum score of 150 points.’
