The Cat Trial 10 Tech Test Challenge
Caterpillar designed the Tech Test to bring awareness to the career opportunities available in technical fields. The event took place at Caterpillar’s Edwards, Illinois customer center and featured 18 dealer service technicians racing against the clock. However, speed alone did not determine the winner. Each contestant received a score based on both their completion time and their performance across multiple technical skill stations.
Three Top Finishers and Their Backgrounds
The competition drew technicians from different dealer networks across the United States, each bringing unique training and experience to the course.
| Place | Technician | Dealer | Location | Training Path |
|---|---|---|---|---|
| 1st | Andrew Holemo | Hawthorne Cat | Southern California | ThinkBig apprentice program, FFA farm power competition |
| 2nd | Ulises Perez | Peterson Cat | Northern California | ThinkBig apprentice program, high school career tech education |
| 3rd | Rene Sanchez | Wagner Equipment | El Paso, Texas | Army 91Bravo diesel mechanic, business management degree |
Andrew Holemo, who secured first place, grew up in an independent equipment shop founded by his father and grandfather in 1965. He participated in the Future Farmers of America farm power competition before entering the ThinkBig program. Ulises Perez came through a high school career technical education program that led him to Peterson Cat’s ThinkBig apprenticeship. Rene Sanchez served as a 91Bravo diesel mechanic in the Army before studying to become an x-ray technician, ultimately choosing heavy equipment repair because he wanted variety and problem-solving challenges.
The course itself was kept secret from participants until they arrived. Holemo described walking into the room as a deer-in-the-headlights moment, noting that the secrecy was so tight that nobody had any idea what they were getting into. Once the competition started, the technicians settled into the challenges and found the experience genuinely engaging.
The Four Core Technical Challenges
The Tech Test obstacle course included four distinct stations, each designed to assess a different dimension of a technician’s capabilities. These challenges mirror the real demands that heavy equipment mechanics face daily in service shops and field environments.
The Cat Can Test
The Cat Can Test was an oversized version of the 3D puzzle that many Cat dealerships use to gauge the mechanical aptitude of job applicants. Contestants had to assemble a complex three-dimensional structure from interlocking metal components under time pressure. Sanchez noted that this jumbo version was significantly harder than the standard test he faced when he interviewed for the apprentice program. The challenge evaluates spatial reasoning, manual dexterity, and the ability to follow mechanical assembly procedures.
Engine-to-Application Matching
In this station, technicians had to match specific Cat engine models to their correct applications across different equipment types. This task requires deep knowledge of engine specifications, power ratings, and the operating conditions that determine which power plant suits a given machine. A technician who understands how engines perform under varying loads and environmental conditions can make better recommendations for repairs and replacements.
Technical knowledge of fluid behavior in mechanical systems is central to engine diagnostics. Concepts such as What Is Pressure Head in Fluid Mechanics directly apply when technicians troubleshoot fuel delivery systems, hydraulic circuits, and cooling loops on heavy equipment.
Troubleshooting Challenge
The troubleshooting station tested the technicians’ knowledge of Cat service procedures and diagnostic protocols. Participants had to identify faults, interpret error codes, and determine the correct repair sequence. Modern heavy equipment relies on electronic control modules, sensors, and networked systems, making diagnostic ability one of the most valuable skills a technician can develop. Understanding how fluids move through systems under pressure is essential for diagnosing hydraulic and lubrication issues, which is why Kinematics of Flow in Fluid Mechanics Discharge and continuity principles form part of the technical foundation for advanced troubleshooting.
Safety Mindset Assessment
The final station required technicians to demonstrate a safety-first approach using the Cat App to perform a machine walkaround and pull a parts order. This challenge assessed both digital literacy and safety awareness. Technicians must be comfortable using mobile applications, digital service manuals, and online parts catalogs as part of their daily workflow. The ability to conduct thorough safety inspections before beginning any service task is a non-negotiable skill in the heavy equipment industry.
These four challenges reveal that modern heavy equipment technicians need a blend of traditional mechanical skills and digital proficiency. The days when a mechanic could rely solely on wrenches and experience are gone. Today’s technicians must understand computer diagnostics, mobile applications, and sophisticated hydraulic and electrical systems all at once.
Training Pathways for Heavy Equipment Technicians
The technicians who competed in the Tech Test came from structured training programs that combine classroom education with hands-on apprenticeship. The most prominent among these is Caterpillar’s ThinkBig program, which partners with local Cat dealers to develop the next generation of service professionals.
The ThinkBig Apprentice Model
The ThinkBig program operates on a rotation schedule:
- Candidates split their time in two-month increments between earning an associate degree in diesel technology at a technical school and working as an apprentice in the dealer’s service shop.
- The dealer covers the cost of tuition and, in many cases, provides housing while the apprentice attends school.
- Apprentices work side-by-side with experienced technicians, gaining practical exposure to real-world repairs and customer interactions.
- Upon graduation, apprentices become full heavy equipment mechanics with a combination of academic credentials and field experience.
Holemo described the support system within the dealer network as second to none. Field technicians have access to senior techs and shop personnel who have likely encountered any problem before. This mentorship culture accelerates learning and builds confidence in new technicians.
Alternative Entry Paths
Not every technician enters through the same door. The three top finishers in the Tech Test illustrate the variety of pathways into the profession:
- High school career technical education: Perez attended a program where he spent half his day at a facility focused on hands-on career training. He started with automotive training and moved into truck mechanics before discovering the ThinkBig program through a dealer facility tour.
- Military service: Sanchez trained as a diesel mechanic in the Army, working on Cat-powered military vehicles. Military training provides structured, disciplined technical education that translates directly to civilian equipment service.
- Family business exposure: Holemo grew up in a family-owned equipment shop, learning customer service and mechanical skills from childhood. This informal apprenticeship built a foundation that formal training later reinforced.
The fundamentals of Fluid Mechanics Civil Engineering are relevant across all these training pathways, as hydraulic systems are integral to nearly every piece of heavy construction equipment that technicians service.
Skills That Go Beyond the Wrench
Modern heavy equipment technicians must develop capabilities that extend well beyond traditional mechanical repair:
- Electronic diagnostics using onboard control modules and software tools
