Finding the First Caterpillar Tractor

Read about how the first Caterpillar tractor ever built — serial no. exp 000_L—was rescued and restored.

Matt Veerkamp was on a parts search 13 years ago in Arbuckle, California, when he was asked to take a look at a rusty old Caterpillar Twenty. Matt wasn’t too excited about the offer, but that changed when he saw the tractor. The serial number stamped on the transmission case and the engine block read, “EXP 0000-L.”

Matt called his father, Doug, with the information. “Yeah, we’ll take a chance,” Doug recalls saying over the phone. After the tractor arrived at the Veerkamps’ home in Placerville, California, where the two run Doug Veerkamp General Engineering, Matt started researching and confirmed they had something special.

“By golly, it was the first brand of Caterpillar tractor of the new company,” Doug says.
