it's rare that I find a business that USES cool old work trucks on the daily job, it's been a couple years since the last landscaping company with old trucks post, but today Hagerty came across a International that's had 219 deliveries so far in ’23, 347 last year

Geneva Materials runs this 1946 International KB-7, and it's really cool to find this company owner appreciates the old iron, as it was what his dad was using when he was a kid. 

Like any vehicle enthusiast, Ron beams when he talks about the care he’s put into the truck. “Originally, she had an 89-horse gas engine,” he said. “I replaced that with a 6BT Cummins out of a school bus—it’s about 160 horses or so—and backed that up with a six-speed manual. With the 3.70 gears I installed in the two-speed differential, it’ll get almost 11 miles to the gallon.”

Some work days are light, with just three or four deliveries. Others are almost nonstop; a few weeks ago he had 12 in a day. That’s a lot of work for any truck, much less one that’s nearly 80 years old.

Ron's daily driver is a '56 IH truck
