Don’t tell this tractor it’s an antique

Don Cummings John Deere 4320 tractor in snow
DIAMOND IN THE ROUGH: This John Deere 4320 still has the original paint and works on Don Cummings’ farm in Seymour, Ind.
Tractor Treasures: This 1971 John Deere 4320 still works whenever there are jobs to do.

This 1971 John Deere 4320 is at home in the snow. Don and Barbara Cummings, Seymour, Ind., the current owners, say the original owner lived in Michigan in an area known for heavier snowfalls. They bought the tractor from their son, who had taken it with him to Ohio, near Cincinnati.

Although it’s in good shape, with the original paint job, this Deere workhorse is still in its working clothes because it still works around the farm, doing everything from running in the field to powering a wood-splitter. It may get a new coat of paint someday — but for now, it still has work to do, Don says.

This model features front-wheel assist. It was a forerunner of the mechanical front-wheel drive common on many tractors today. An issue on some John Deere tractors, Don says the front-wheel assist works well on this tractor.

According to, the John Deere 4320 was built in 1971 and 1972 to fill a horsepower gap between the 4020 and the 4520 and 4620. Some referred to it as a 4020 with a turbocharger, but historians say both the engine and final drives of the 4020 were upgraded for the 4030. You could have bought one new in 1972 for $12,000 list price. Records show that 21,485 4320 tractors were built. It featured a six-cylinder diesel engine.

The John Deere 4320 produced just over 102 hp in tractor tests at the drawbar, and 116 hp on the PTO. An optional rollover protective structure with canopy and optional cab were available.
