Just off State Highway 166 in southeastern Kansas lies the small
farming community of Cedar Vale, population 760. Years ago, the
highway ran through the center of town, but time and progress
pushed the road north and around Cedar Vale’s direct influence,
making it unlikely a traveler driving by would even notice the
town.

Truth be told, the average urban traveler probably welcomes the
highway’s gentle bypass around the edge of the town, allowing
him or her to continue traveling without pause. And yet, a simple
excursion into Cedar Vale reveals a fascinating relic from the days
of steam.

For the rural-minded, turning off 166 and driving into Cedar
Vale on the old highway presents a familiar picture. Situated on
gentle hills overlooking the Caney River, Cedar Vale’s
one-block-long main street houses the expected collection of
small-town businesses, including an insurance office and a few
shops selling knickknacks and antiques. But sandwiched between a
few buildings in a haphazard park that doubles as a parking lot, an
old steam tractor sits quietly, an antique Case separator its only
companion.

FIRST LOOK

An initial examination shows a nicely constructed steam traction
engine furnished with a vertical boiler and a single-cylinder
engine. A three-wheeled machine, the single front wheel is bolted
to trusses that attach to a circular rack held by the frame. A
pinion off the steering gear engages the rack for turning.

Power from the engine passes through a crankshaft equipped with
a wooden-shoed clutch to engage traction drive, and a differential
gear on the right side provides the differential action for the
rear drivers. A 6-inch-wide, 32-inch-diameter, six-spoke flywheel
is mounted on the left side of the crankshaft, and a smaller, solid
flywheel is mounted on the right, just beyond the crankshaft gear
that drives the differential idler gear. Looking closer, however,
the tractor presents a few surprises.
