Henry ‘Hank’ Krohne sitting on one of his Krohne
tractors sometime around 1941. Hank built the chassis himself,
sourcing the running gear and other hardware from readily available
new and used sources. All told, he built 50 of these tractors, most
of them evidently staying in Michigan.

Henry ‘Hank’ Krohne of rural Hartford, Mich., a large
tree fruit, vegetable and grape farmer, needed a new tractor. In
early 1941 farm machinery was hard to acquire, so Hank decided to
take matters into his own hands, turning his attention to building
his own.

Hank built his tractor drawing from a combination of new and
used parts. His tractor used a Ford Model A motor, a Ford Model A
transmission coupled to a Ford truck transmission (which was
evidently used much like a transfer case, most shifting being done
through the Model A transmission), a Ford truck rear end, an Allis
Chalmers gas tank, a custom-made hood, 16-inch front tires and
12-inch by 28-inch rear tires, all pulled around a 6-inch
channel-iron frame. The resulting tractor was fast and durable.
Painted a distinctive bright red, these tractors sold for $800 in
1941, and all told Hank made 50 Krohne tractors.

The Bronte Winery and bottling plant in nearby Keeler had three
Krohne tractors on their 140-acre grape vineyard to disk and haul
out wooden boxes of grapes on a 4-foot by 10-foot trailer.

The only known surviving Krohne tractor, which has been sitting
idle for the past 45 years. Robert was able to buy this tractor the
same day he finished putting this story together.

The Krohne tractor was hardly Hank’s first offering. Hank
was a very good welder, and when he was 28 years old he designed a
400-gallon spray rig with a wooden tank, a John Bean pump and a
4-cylinder Willys motor. As the driver drove along at about four
mph a spray operator (standing on top of the tank in a square,
welded pipe frame so tree limbs would not knock him off) used a
spray nozzle attached to a rubber hose to spray the trees. The
sprayers sold for $1,200.

Louis Gelder & Son, a large Oliver tractor dealer 15 miles
away in Millburg, commissioned Hank to build several of the
sprayers. The dealer was in the middle of southwest Michigan’s
‘Fruit Belt,’ and the sprayers were much needed at the time
with farmers changing from livestock and grain operations to fruit
and vegetable farming.

A surviving photograph, also taken around 1941, of Hank’s
custom spraying unit. Hank built around 70 of these units, which
used a John Bean pump and a Willys 4-cylinder engine. The operator
stood in the square platform on top as the unit was pulled

Hank built about 70 sprayers, and he also built a duster for
applying powder on fruit trees. The duster used a Root blower and
motor mounted on a trailer. Additionally, Hank also made farm
trailers -an 8-foot by 16-foot flatbed for fruit and vegetables and
a 4-foot by 10-foot for use in grape vineyards.

Hank’s inventiveness didn’t stop with farm implements.
Hank’s neighbor, Curtis Coats, needed something to dig canals
and build an island on low land he owned on a very large lake. Hank
welded up a 20-foot by 30-foot barge, then mounted a mud-sucking
pump, a gas engine, some hose and some pipe. The barge was used to
dredge out canals to create a large island on Paw Paw Lake in the
Coloma-Watervliet, Mich., area. Today, there are still houses on
the island and on the canals. He also did welding work for the oil
wells in Bloomingdale, Mich., and his wife, Marie, says they called
him day and night to come weld for them.

The only known Krohne tractor left has been sitting in woods for
the past 45 years, and I have just purchased that tractor. Hank
still has three of his own spray rigs on his farm.

This area has, interestingly, been the site of a lot of
independent manufacturing. Within a 20-mile radius Krohne, Parrett,
Friday, Love and Kaywood tractors were made, all designed for use
on fruit and vegetable farms. They also were specifically designed
to be faster and for hauling fruit and vegetables to

Hank Krohne is 86 years old now, and his son John runs the farm
now – about 300 acres of mostly open land planted with pickles and
