These big and powerful machines are actually not strangers to Maple Grove Raceway.

Throughout the season, diesel-powered tractor trailers transport racecars and equipment to dozens of events. When the NHRA Mello Yello Series arrives in October for the Auto-Plus NHRA Nationals, it’s a neat sideshow watching the transports wind their way down the country roads to The Grove.

On Saturday, July 27, the trucks won’t be supporting actors; they will have the top billing.

The inaugural Keystone Diesel Truck Nationals presented by Mack Trucks will have a big rig show and shine as well as Diesel pickup drag racing and big rig drag racing.

Gates will open at 8 a.m.

Drag racing will feature brackets for both types of trucks. Pickups will have classes capped at 32 racers and big rigs will have 16 with the number of fields unlimited in both classes.

There will be a head’s up shootout with manufacturer awards for the fastest trucks. The bracket winners will also meet in a runoff race for the title of “King of The Grove.”

Hunter Keystone Peterbilt is sponsoring the Big Rig Show and Shine that has 12 trucker classes and includes a class for truckers’ bikes.

Over 79 awards are to be presented with 39 class places, 21 specialty awards, 16 fun trophies and three best of show.

Also taking part in the show are the Antique Truck Club of America, Exit 21 and the American Truck Historical Society.

Gates open at 8 a.m. Adults are $20 with teenagers ages 13-15 $10 and children 12 and under free with paid adult. Parking is free.

Show and shine entries are $40 and race entries are $50.

Rain date for the event is Sunday, July 28.

Additional sponsors include R.R. Commercial Services Inc., FA Unlimited, Triple K Fleet Services, Trik Trux by Pro-Fab Associates, Elite Service Inc., Polish This, Delaware Valley Concrete, Class 8 Parts, Denver Truck Painting, Detroit Diesel, Xtreme Diesel, Bender’s Buffing Polish and Savoy’s SMS Inc.

Admission is $20 for street driven cars and $25 for entries on a trailer. Spectators are $10 with children 12 and under free.
