Event Information

Location:  Pinnacle Bank Arena, Lincoln, Nebraska (Loading Dock, north side)

School teams 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.

Section I, including teams from Districts 7-12 will start promptly at 9:30 a.m.

Section II, including teams from Districts 1-6 will start promptly at 1:00 p.m.

Note: Contestants will receive a school number, ie: 1-50, and an indvividual number, ie:  A, B, C, D. (example 32A)

Approximately 100 students will be in each 2.5 hour time period allotted to the event. (2 main groups). Individuals will be divided for 6 of the activities and rotate every 15 minutes. (Approximately 15 contestants will begin at each activity table.)

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.

Agricultural Technology and Mechanics Events:

Individual Events: 

Each team member will rotate through 6 individual activities with a maximum time of 15 minutes for each activity. Each individual team member will receive a maximum individual score of 50 points per station with a total individual score of 300 points. Individual activities are listed as follows:

  1. A small gas engine identification practicum of tools and, parts with a few micrometer measurements.
  2. A 25 question test over small gas engines and theory.
  3. Wiring a single pole switch circuit to a light and outlet. (A 1' by 2' board will be provided with switch and lamp boxes pre-attached and required lengths of wire pre-cut. A switch, a light fixture, an outlet, and wire nuts will be available. Competitors would strip the insulation to the correct length and attach the wires to the devices for the competition. The devices will not have to be tightened or grounded to the boxes, rather left out to check correct procedures. Sixteen boards will be laid out with 8 extra available during each rotation to provide enough ready to use for each group. Completed boards will be replaced with blanks, scored, and 'reset' after each rotation. A diagram will be provided at the activity.
  4. A 25 question test over basic electrical terms, safety, etc.
  5. A forklift  to identify 10-25  basic parts and safety decals.
  6. A 25 question test to find specifications from a forklift operator's manual. (Recommended tire pressure, load capacity, safety protocols, travel speed, etc.) Operator manuals, or copies, will be provided at the activity.

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.

Registration Fee

There will be a $40 registration fee per team participating in the State Agricultural Technology and Mechanics Event. If there are dollars left over after all expenses are paid, NCTA will keep the extra in a separate auxiliary account managed and used to fund the event in future years.

To help with school billing, the fee will be included in the invoice with the rest of CDEs to UNL and fees will later be transferred to NCTA

Required Supplies/Safety 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 someone know. Teams will need to bring the following items with them:

  1. #2 pencils per person
