Back in the March 2003 issue of Gas Engine Magazine, I
wrote about the discovery and restoration of my 1948 Case SI,
serial no. 5212750. It is an unusual tractor, because where the
belt pulley would normally be located, there is a two-speed gearbox
instead. The following information is printed on the gearbox:


During the Case’s restoration I tried, unsuccessfully, to
find information about Evans winches, about how the missing winch
mounted on the tractor, and what was the winch’s intended
purpose. However, since the article was published, all of these
questions have been answered, due to the many alert and
knowledgeable readers of Gas Engine Magazine. I received
many letters and phone calls from readers who had information on my
Case, enabling me to piece together the details and history of my
winch tractor.

Alfred Evans

Alfred Way Evans started his company after purchasing the rights
to manufacture a hand-operated winch called a Pull Jack. Once
established as a manufacturer, he developed a more powerful,
powerdriven winch that mounted on Fordson tractors. This unit was
sold and shipped all over the world and was used extensively for
clearing forests. When Ford switched from the Fordson to the 9M,
Evans turned to Case for a suitable tractor. He ended up mounting
his winch on Case SI tractors fitted with steel wheels, which
proved to be a very effective combination; the company described it
as a ‘land-clearing and stump-pulling tractor.’

Evans liked performing dramatic demonstrations of his equipment
to prove its efficacy, and on one occasion he used a Case winch
tractor to pull over a 7-foot-diameter cottonwood tree. He hooked a
line about 25 feet high in the tree, and using snatch blocks and a
tackle, he pulled the tree away from the tractor and down to the
ground. For another demonstration, he suspended a 5,600-pound
weight from a cable controlled by a Case winch tractor. He then
stood under the weight and had the winch operator lower the weight
to just touch his out-stretched fingertips. Putting his arm down,
he had the operator lower the weight until it just touched the top
of his head. Talk about trusting your own design!

To further demonstrate the efficiency of his winch, Evans
conducted demonstrations wherein a six-man crew pulled as many
8-inch stumps as fast as they could. In one case they pulled 10
stumps in 58 seconds!

Typically, Evans ordered a group of tractors from the Case
factory in Racine, Wis., and they were shipped to his plant in
Gloucester, Va. Once the tractors were at his factory, workers
mounted the Evans winches, painted the tractors silver or olive
drab, and then shipped them to customers around the world. Some
helped build Denison Dam and Reservoir in Texas, while others
cleared the jungles of Africa or South America. The U.S. Army Corps
of Engineers was one of the biggest customers for Evans

Pulling it Together

Among the helpful readers who provided me with information was
Ray Gay, of Ellensburg, Wash. After seeing the March 2003 article
in GEM, Ray called to tell me he owned a complete and
running Evans winch tractor, and he invited me to see it. Since Ray
lives only 90 miles away, I made the trip at my first opportunity
so I could inspect and take pictures of his very special tractor.
Ray and I compared serial numbers, and we found that our tractors
are only 71 numbers apart; they were built in the same batch at
J.I. Case in May 1948.

Of great interest to me was the chance to inspect a complete
Evans winch assembly, mounted and functional. The winch assembly,
which is missing on my tractor, mounts directly on the back of the
Case, and it takes its power from a sprocket on the two-speed
gearbox on the side of the tractor. A chain from this sprocket runs
around the rear axle to a very large sprocket on the rear-mounted
winch, where another set of reduction gears drives the cable drum.
A control lever on the winch selects low, high or neutral gear, and
a ‘handle dog’ locks the lever in position. Vertical
rollers acting as fairleads prevent wear on the cable as it exits
the spool. The entire winch is massively built and can clearly pull
quite a load. A loop of steel cable is attached to the winch frame
and is suspended under the tractor and brought up to the front.
This serves as the anchor point for pulling.

A rather elaborate set of instructions is engraved on a plate on
the chain guard. The two gearboxes, plus the ‘handle dog,’
make for a lot of levers to pull and push. In general, a high gear
ratio was used to pull in the slack cable through all the tackle,
then the operator switched to a lower gear for heavy pulling.
Another plate on the control handle identifies the manufacturer as
the ‘Evans Clearing Corp.’

The End of Evans Winches

The development of modern earth-moving equipment after World War
II (with items such as hydraulic backhoes and large dozers coming
to the market) spelled doom for the Evans land-clearing winch
tractors. When Evans died in 1950 at the age of 66, his nephew took
over the company. By this time, sales of Evans winches were in
decline, a trend that continued until the company was eventually
forced to close a few years later.

Alfred Evans’ handsome headquarters and manufacturing
building in Gloucester is now an auto parts store and antique mall.
Even so, some of his winch tractors are still alive and well.
They’re rolling – and working – tributes to his inventive
skills and relentless drive.

I am grateful to Betty Jean Deal, director of the Gloucester
Museum of History, for her help in tracking down sources of
information; to Bill DeHardit of Gloucester, who shared a wealth of
history and photos of the Alfred Evans Clearing Corp.; and to Mike
Intlekofer for research assistance.

tractor, can be reached at: P.O. Box 5, Ellensburg, WA 98926.

Kirk Unzelman has been, at various times, a cowboy,
rancher, farmer, army medic, truck driver and mechanic. He is
