Let's Talk Rusty Iron: Former workers recall the excitement of early Firestone tire testing operation.
In this famous photo, Harvey Firestone and his son, Leonard, are digging potatoes. The tractor is a Farmall, officially called the Farmall Regular after the Farmall 30 was introduced in 1931. Notice the wheel weight on the potato digger wheel to give the ground-driven machine more traction.

The International Metro test truck, hooked to an unstyled John Deere Model A tractor in about 1941. The high fence in the background was built by Harvey Firestone to keep out the traffic noise from busy Ohio Route 14, which is just beyond the fence. The John Deere tractor is equipped with unusual dual rear tires that were probably 6- or 7-inch-by-38-inch.
