contemplate the job of removing rust in their volunteer
restoration of a rare 1918 Bean tractor. Under the direction
of Parsons, students hope to restore the vintage farm
machine to showroom condition. From left are students

What looks like a rusting hulk of machinery
in the fenced-in area behind the physics/engineering shop is in
reality a rare treasure of California’s agricultural past
– awaiting restoration.
The rusty diamond in the rough is a 1918 Bean tractor
that Dave Parsons, machine shop supervisor, and a volunteer crew
of engineering students hope to restore to “showroom ready”
condition as a reflection of the pride farmers had 85 years ago
when the tractor was new.
Parsons, a frequent visitor to the Antique Gas and
Steam Engine Museum in Vista, arranged to borrow the tractor for
a restoration project that would enable university students to have
the hands-on experience of repairing and refurbishing a vintage
piece of farm equipment.
The project also will provide students with an insight
into the design elements and engineering aspects of early farm machinery,
says Parsons, who estimates it will take up to two years to complete
Parsons plans to involve freshmen and sophomore students
in the project, so they can apply lessons learned in the machine
shop to future engineering projects.
“The largest amount of work needed on this project
will be in rust removal,” says Parsons. “This will involve
taking the tractor apart, cleaning, repairing or replacing the individual
parts and reassembling the machine to working condition.”
Sandblasting will be used to remove much of the rust.
“If there are any parts to be fabricated, the
shop is certainly capable of that. The frame was bent in an automobile
accident and will present a challenge to straighten out, but it
is nothing that can’t be solved,” he adds, noting that
some adaptation of parts may be required – such as a radiator.
Students working on the project will utilize the shop
facilities to machine new parts as needed, under Parsons’
The Bean tractor is one of nine known to exist, according
to the machinist. It was manufactured in San Jose in 1918 and was
probably used to pull orchard wagons in the Sacramento Delta region.
Unlike tractors of a conventional design with two large wheels in
the back and two smaller wheels in front, the Bean model has a single-track
drive in the center (like the track on a bulldozer) and two trailing
wheels, says Parsons.
The operator sits on a pivoting carriage attached
to the rear wheels and controls the direction by turning the joint
in the middle. There is no steering wheel. The tractor is powered
by a small Le Roy four-cylinder engine off to one side. “It
was not one of the better designs of its era,” Parsons admits.
In addition to renovating the tractor, Parsons plans
to take groups of students to the Vista museum to show them other
examples of antique farm equipment.
When completed, the tractor will be displayed on campus,
then retuned to the museum’s permanent collection. Signage
will indicate that Cal State Fullerton engineering students restored
