Thirteen years ago, a freak accident left Don Dougherty in the
hospital and in a coma. When he came to, a new life began, both for
him and the machines he restores.

On a September day in 1990, Don Dougherty was getting ready to
help his mother move out of her rural Colfax, Calif., home when a
fire in the adjoining trees grabbed his attention. That summer and
early fall had been devastating for the area as fires, sparked by
lightning and fueled by drier-than-normal conditions, broke out
spontaneously across California. It was, Don says, ‘a little
fire,’ and he immediately went to work putting it out.

What Don couldn’t see was what caused the fire; a
high-voltage line had snapped when a dead tree fell across it,
momentarily jumping to ground before bouncing back up, only to hang
some three or four feet from the ground. Putting out the fire, Don
stepped back, contacting the line with his shoulder and the left
side of his face, creating a conduit that let 7,200 volts course
through his body.

‘I woke up in the burn unit in Sacramento three weeks
later,’ Don says. ‘After getting my senses back, I wanted
to put a positive spin on a negative situation. During that whole
event, my heart never stopped, so I put a tag on my truck; ‘STL
TIKIS.”

That event changed Don’s life forever, and in large measure
it’s what pushed him into antique tractor restoration.
‘When you face a catastrophic injury, a person wants to get
back into their comfort zone. You want to consider yourself normal,
so you do things that are aimed at trying to get yourself
normalized. For your own self-esteem and clarification of yourself,
you’re trying to get back to where you were, so you look for a
path that works for you. I’ve always loved antique trucks and
tractors, and restoration was just a natural extension of that.
That may seem bizarre, but that’s what I did.’

Less than a year later Don applied the moniker on his license
plate to a new business, STL TIKN Machinery, concentrating on
restoring antique tractors, crawlers and trucks. Don wasn’t
exactly new to the restoration process when he launched his
enterprise. ‘I had been doing a little of this, but I was the
public works director for Grass Valley, Calif., before my accident,
and I didn’t really have time to do restorations like I wanted
to,’ he says.

These days, however, Don takes the time, and since starting up
STL TIKN Don and his crew have finished 15 complete restorations,
on top of repairing other people’s machines and completing
their unfinished restorations. The Yuba Ball Tread featured here is
just one of those restorations.

Don’s Yuba is equipped with a 606 cubic-inch four-cylinder
Wisconsin Model D. Yuba used engines from a number of different
manufacturers, including Continental and Wisconsin, and is said to
have built at least one of its own.

The Ball Tread

The history of the ball tread, while a little murky, has seen
some documentation. According to R.B. Gray’s book, The
Agricultural Tractor, 1855-1950, the Yuba’s ball tread design,
where the machine’s crawler tracks ride on balls rolling in a
race, was the brainchild of Clarence Henneuse, a shop foreman at
the C.L. Best Tractor Co. in Elmhurst, Calif. It may not have been
an original idea, however, as a Charles Pierce of Milwaukee, Wis.,
evidently patented his own ball tread scheme in 1888. Be that as it
may, Henneuse started work on his own ball tread tractor, and some
time around 1910-1912 Henneuse, with the help of a Mr. Frame and
W.J. Benson of San Jose, Calif., enlisted Alfred Johnson of
Winters, Calif., to design a transmission for the new machine.

In 1912 they took their design and headed to Detroit, Mich.,
where they teamed with machinist Ben Middleditch. At this juncture
they formed the Ball Tread Co., and working out of
Middleditch’s shop they built two different tractors, a Model A
and a Model B. According to information collected by California
historian Lorry Dunning, Davis, Calif., it was winter and the
ground in Detroit was frozen when the tractors were finished, so
they were shipped to California where they were put to work.

Around 1913-1914 the Yuba Construction Company of Marysville,
Calif., purchased the Ball Tread Company and began manufacture of
the Yuba Ball Tread in their Marysville facility. The company’s
initial offering was a 20 HP Model 8 and a 30 HP Model 12, and
demand for the machines was evidently strong; according to numbers
collected by Lorry, it appears at least 900 Yubas were built at the
Marysville facility between 1914 and 1916. This success evidently
prompted the company in 1917 to set up a second manufacturing site
in Benicia, Calif., some 90 miles to the south in the San Francisco
Bay area. The company’s name formally changed to Yuba
Manufacturing Company at the same time.

Development of the Yuba Ball Tread continued, and in 1918 the
company introduced the Model 40-70, the ‘Big Yuba,’ as it
was called. New tractors continued to issue from the two factories,
and all told the company produced nine different models and 2,440
tractors before it ceased operations in 1931. Judging by available
information, the 1917-1921 period marked the company’s zenith
in terms of production.

one of 724 20-35s made, and only 10 survivors are accounted for.
The handle above the nameplate is for transmission engagement.

Just what caused the Yuba Ball Tread’s failure is unknown.
It’s highly likely the company was a victim of Depression-era
economics. But it’s just as likely the company’s signature
offering, the ball tread, was its undoing. The ball tread-design,
while certainly unique and not without its benefits, was also
troublesome.

The balls were lubricated with engine oil, but since they were
open to the elements, dirt mixed with the lubricating oil, creating
a grinding paste and prematurely wearing the balls. This resulted
in loose tracks, and when the machines crossed a depression the
balls would often fall out. According to Don, some owners hired
young boys to walk behind the tractors to pick up any balls that
happened to fall out, failing to understand that worn balls were
the root of the problem.

1916 20-35

Don’s machinery interests are pretty eclectic, which goes a
long way towards explaining his interest in the Yuba. He saw his
first Yuba at the 1993 Grass Valley, Calif., show when John Boehm,
Woodlawn, Calif., displayed one. Seeing the Yuba, Don thought,
‘That’s the strangest thing I’ve ever seen in my life.
When I found out about the Yuba Oscar had, I decided to buy
it.’ Oscar, in this case, would be the late Oscar Cooke,
proprietor of the legendary Oscar’s Dreamland in Billings,
Mont., once billed as the largest private collection of tractors
ever assembled. When Oscar died in 1995 his collection sat in limbo
until a decision was made to auction it off. In 1998, before the
final auction, Don had the opportunity to buy the Yuba – he snapped
it up. A 1916 Model 20-35, this was the third largest, and most
popular, tractor in the Yuba line.

Don and his crew spent the next year restoring the 20-35, one of
only 10 known survivors out of an estimated production of 724 Model
20-35 tractors. Don’s Yuba survived, Don believes, mostly
because of someone else’s mechanical ineptitude. The Yuba’s
four-cylinder Wisconsin Model D engine has an externally mounted
oil pump, and a line runs from the pump to a ‘Telltale,’ a
spinner that lets the operator know at a glance if the engine has
sufficient oil. The oil line is supposed to tee at the Telltale,
with a line running from there to the engine’s main oil galley.
But instead of teeing off, the line had been routed through the
Telltale and then to the main oil galley. This severely restricted
the oil supply to the engine, resulting in catastrophic failure of
the bearings. When Don and his crew tore the engine down the
bearings were shot, one piston pin had separated and badly scored
the cylinder, and another cylinder was scored from lack of
lubrication.

In the end they had to press in two new sleeves, no mean feat on
an engine with blind cylinders. The cylinders and head of the
Wisconsin were cast in pairs as a unit, which adds up to a lot of
extra work when it comes to boring and sleeving the engine. The
camshaft and roller lifters were okay, and the timing gears,
although a little thin, were deemed useable. The babbitt crankshaft
bearings were all replaced, and Don says the finished bearings were
so beautiful he ‘didn’t want to put the damn thing back
together.’

The Yuba’s transmission is an interesting affair, in that
it’s really three separate units. A spur gear, two-speed unit
provides power to two paragon planetary units; one for each track.
The two planetary units allow for the separate forward and reverse
action in each track, with a multi-plate clutch in each unit giving
forward motion and a band giving reverse. A leather belt couples
the engine to the transmission; there is no clutch.

Don looks on as one of his crew puts his back into starting the
Yuba at last year’s EDGE & TA Southwest Regional Show in
Grass Valley, Calif.

The Yuba’s unique ball-tread system, which uses 280,
2-1/4-inch steel balls as rollers for the treads, received its fair
share of attention, including new balls sourced from a bearing
company in Massachusetts. By 1999 the Yuba was finally ready to
roll, making its first outing at the Tulare, Calif., show, followed
by the Carson Valley Show in Carson City, Nev. ‘We had rebuilt
it and restored it, but we didn’t know how the drive train
would work. The balls fell out of the tracks at both shows,’
Don says. It takes about two hours to put the balls back in, but to
hear Don talk about it, it’s all just part of the package.

Driving Force

That attitude, one of calm reservation and unflinching
perseverance, is a direct result of Don’s accident, an
experience that changed his life in every imaginable aspect, and
that drives him in everything he does.

The machines Don restores are, like himself, unique. Their
restoration and survival are somehow inextricably bound in
Don’s own sense of survival. Had Don never stepped into that
line that September day, his life might have followed a very
different path, and he might never have turned his full attention
to restoration. And if he hadn’t, the old iron community would
be that much poorer.

Don would like to recognize the following for their help in
the restoration of the 1916 Yuba Ball Tread: Scott’s
