A little heat and humidity was no match for the annual Hanceville Antique Tractor & Engine Show Saturday, which, in its 20th year, has shrugged off more than a few summertime scorchers for a nostalgic look at southern agriculture’s early mechanized roots.

Case, John Deere, International, Ford and more: as in years past, this year’s show brought a mix of antique tractors and other fascinating pieces of gear and motor-operated machinery, as well as plenty of guests, whether passionate tractor buffs or simply curious newcomers.

Larry Alldredge of Brooksville brought his unrestored and weathered 1950 Case tractor to the show, but its mission wasn’t about looks; rather, it was all about function. Attached to a portable, pulley-driven millstone, Alldredge’s tractor stayed busy powering the century-old mill to the delight of guests more than happy to take home a bag of freshly-ground corn meal.

“This thing’s 101 years old. See, here’s the original serial number,” said Alldredge, gesturing to the all-original wooden casing. “The company that made this out of North Carolina is still in business. For something that was made 101 years ago, it’s pretty sophisticated — and it still does the job.”

Bonnie Hamrick Brannan, who’s helped keep the event going since Jimmy Hamrick, her father and the show’s founder, passed away in 2010, said her dad got the show going back in 1998 after he and his friends came away from an out-of-town show wondering why the same type of event couldn’t work at Hanceville.

“They had been going to other shows, and one of those folks said, ‘Why can’t we have one of these at Hanceville?’ So he started looking into what it would take to make it happen — and here we are today.”
