Reviving Tradition at the Mecca of Racing

And the technology that helps make it happen

As the pace car flees the track, the roar of 24 engines packed with over 400 horses of pure fury collectively redline, blasting the go-kart-sized midget cars around the track at an explosive pace. The cataclysm of controlled chaos is striking, filling the chests of thousands of spectators with thunder — which is further amplified and rivaled by the crowd’s roars of excitement. As the dirt flies and adrenaline surges with every jockey of position, the greatness of this age-old tradition is made all the grander by its high-profile setting.

The Indianapolis Motor Speedway (IMS), the birthplace of Indy cars and incubator of racing innovation, continues to set the pace by expanding on its 109-year history. September 2018 marks the green flag flying for the first sanctioned dirt-track race on these hallowed grounds


Three primary parties have made the new dirt-track venture possible. The United States Auto Club (USAC), the world's largest race-sanctioning body, has been the primary driver.

"Our main goal is getting the next generation excited about and involved in racing," explains Kevin Miller, president and CEO of USAC. "Whether in a go-kart or Indy car, where better to host races than at the track every 13-year-old dreams of driving someday? Many Indy and NASCAR™ racers come up through dirt tracks, and bringing that tradition to IMS is something we're very excited about."

As for the folks performing the dirt work on the track, there's a unique tie to the project. "We actually own a race team of three vehicles, each with its own driver, that travels the full circuit to all national events," says Scott Petry, founder, owner, and president of Petry Excavating of Greenfield, Indiana. "There's so much history at Indy. I was honored when they asked if I wanted to be involved."

Lastly, West Side Tractor Sales of Indianapolis donated the equipment and technology for the project. "On-site here, we've got a 750K LGP Dozer with SmartGrade™ technology, another 750K LGP with Topcon aftermarket technology, a Topconready 772GP Motor Grader, and a 317G Compact Track Loader equipped with the Leica Level-Best System," Mason Adkins, grade control specialist for West Side, lists the impressive lineup of equipment. "Tying all that technology together is our Kespry Aerial Intelligence System."


Scott Petry, founder, owner, and president of Petry Excavating, Greenfield, Indiana, owes the better part of his knowledge and experience in construction to working for his father-in-law. "He's just a one-in-a-million guy. He's taught me so much. When it came time to branch out on my own, it was an easy transition."

Having recently hit the company/s 25-year milestone, Petry is on the up and up when it comes to its usual projects including hotels, shopping centers, car dealerships, and the occasional racetrack. "We have 14 employees, and two of them are my sons. They both went to college and started as laborers here. Eventually, we were growing so fast, we had to change how we worked. I'm still involved every day, but they've really taken the load off me."

"Running Deere equipment is in our blood. My grandfather was a Deere mechanic, my dad worked at Deere for a while, and we always ran Deere equipment on the family farm. When I first started the company, West Side Tractor Sales was the only dealership to give me the time of day and set me up for success. It’s just been a great relationship — Deere has supported us 100 percent along the way, and we appreciate what they are and what they stand for."

Where better to implement cutting-edge technology than at IMS, a racetrack purpose-built for spurring innovation? "We're pretty much pulling out all the stops on this one," explains Adkins. "They wanted to base this new track at IMS on the Kokomo track just north of here, so we flew the Kespry drone to gather that survey data. Then we mapped it onto the Google Earth image of IMS and adjusted the data points and track size to fit the space."

Getting the base information was just the start of the Kespry system and GPS technology advantage. "After test-running the track, we realized the smaller version set corners that were too tight for this type of race. The files are flexible, so all we had to do was adjust the data in the CAD file and re-upload it to the machines. From there you pretty much press 'go' and the machines do the work."


According to Adkins, the best part about the technology is how simple it is to use. "I can hand a customer the iPad, and they'll have the site set up and the drone running within five minutes. It's extremely user friendly."

As for Petry, the return on investment with SmartGrade is what sealed the deal. "We're a smaller company, so it was a big chunk to bite off, but it paid for itself in six to eight months. We did a big parking-lot project without the technology that took about four-and-a-half days to finish. The next week we put the technology on and did a similar job — a nine-acre lot and building pad — and finished grading in a day and a half, with two guys instead of six. We'd never go without it now."

Petry Excavating, Inc. is serviced by West Side Tractor Sales, Indianapolis, Indiana.

Fine-Tuning with Kespry Aerial Intelligence System

Step One

The Kespry drone flies over the jobsite to quickly and precisely gather survey data.

Step Two

Using that data, CAD files are created to illustrate what the site will become.

Step Three

Those files are easily uploaded to GPS-enabled machines.

Step Four

The computer does the rest! Simply drive the machine and the blade automatically adjusts as needed.
