Yard Horse / mule Tractor Scooter - All Purpose Scooter

1. All-Purpose
Yard. Horse
This 40-m.p.h. scooter earns its keep
the year round by converting to five
powerful machines for use around the house
By Alfred W. Lees
IT DIDN'T seem likely—until we saw for ourselves.
The letter from Clarks Summit, Pa., described a
homemade scooter that pulled apart for portability
and boasted a set of attachments to convert it into: a
hauling tractor, a snow plow, a power lawn mower,
a portable electric generator, and a pump.
The inventor, anticipating our skepticism, enclosed
a map labeled "Route to Douglas Biesecker." So PS
photographer Bill Morris and I drove out to investi-gate.
We found a young man waiting for us, up a
country lane identified by the Biesecker mailbox. He
straddled a neat-looking two-wheeler with a frame
welded up from black iron pipe, angle, and strap iron.
"Put it through its paces," we suggested.

2. WATER FROM A CISTERN or any natural source
can be brought to the job site by coupling the
feed and discharge hoses to a 1,000-gallon-an-
hour pump, powered by the scooter motor.
EMERGENCY LIGHT SOURCE is rigged by bracket-ing
a 110-volt, 1,000-watt generator to the
frame. It's propped on a bolt; turning a wing-nut
pivots the assembly for belt tension.
LURE OF THE OPEN ROAD calls scooter from its
chores. Since all attachments are complete in
themselves, the scooter totes no extra burdens
when stripped down for road travel.
SCOOTER CONVERTS TO MOWER in three steps:
Auxiliary frame sets steering column vertical;
mower unit replaces front wheel; large wheel
replaces speed pulley in drive train.
1. The scooter. Biesecker obliged by
jerking the four-cycle, three-horse motor
to life and roaring out onto the road at
40 m.p.h. In a flash he was gone over the
crest of a rise. Seconds later, he reap-peared,
banking back into the lane. He
killed the motor, hopped off, and de-tached
two levers from the handlebars.
"The throttle control is the standard
type used on power mowers," he told us.
"The cable's other end is connected to
the carburetor throttle lever. The brake
cable should be taped to the frame in
several places, but I clamp it to the steer-ing
column so it's removable."
Next, he withdrew a long T-shaped pin
that passes through the vertical pipe
brace in front of the seat. The 1/4"-by-
17-1/2" rod holds the ends of the steering-column
braces in pipe-coupling sockets at
each end of this brace. Biesecker lifted
the scooter's separated halves into the
trunk of his car. "Total weight's about
60 pounds," he announced.
2. The pump. "While the scooter's in
the car," said Bill, "why not drive back
by the barn cistern and demonstrate your
pump by giving the car a hosing?"
Biesecker had the setup nearly com-pleted
by the time Bill had his camera
equipment ready. He'd reassembled the
scooter, set it up on its kick stand, and
bracketed a small pump to an accessory
rest—which consisted of a short cross pipe
with pins at either end. A bolt, project-ing
beneath the pump's mounting base,
was seated in a hole in the frame brace

in front of the seat. By turning a wingnut
on this bolt, Biesecker pivoted the pump
upward to put the proper tension on the
long belt that connected it to the drive
pulley. He fed a hose into the cistern and

coupled the other end to the pump. Soon
he was directing a sturdy spray at the
soaped-up windshield.

auto into the twilight interior of the

4. TO TAKE IT APART for portability, you detach
throttle and brake from the handlebar and
pull a pin that passes through the center frame
barn. Biesecker set up a photographic
light bar and replaced the pump with an
electric generator equipped with an iden-tical
mounting bracket and adjustable
prop-bolt. After starting the scooter
motor again, he lifted the car's hood and
directed the light exactly where he need-ed
it to work on the engine.
"Actually," he said, "this portable gen-erator
is handy in lots of places beyond
the reach of city power. I've used it for
outdoor photography, night repair work
in the fields, and even to rig a light for a
hunting camp. It's handy in case of power
failure."
Biesecker detached the generator. The
coupling pin was pulled once more, and
the scooter began to lose its identity.
4. The mower. To ready the power
unit for its next function, the high-speed
drive pulley was replaced with a power
wheel of twice the diameter. The axle
nuts were loosened to drop the front
wheel from its slotted fork.
Nearby lay a handleless lawn mower
and an extra section of pipe frame.
Biesecker loosened two studs threaded
through the handlebar column and
slipped this upper unit off the steering
shaft. "All shafts are cold-rolled steel,"
he informed us. "This one's 3/4" in diam-eter
and 13-3/4" long. Note how I filed it
flat in two places at the back to seat the
studs." He slipped the angled steering-column
housing up off the shaft and
pointed out the coil spring that it had
rested on, where the shaft was welded to
the wheel fork. "That spring stays," he

said, slipping the new frame down to butt
against it. I had a question:
"Why's the separate frame necessary?"
"To set the steering column vertical.
The scooter's column slants at 15 de-grees,
but the mower's has to set upright.
Notice how all the pipe-column housings
are slightly counterbored at each end to
take brass bushings. These are pressed in
tight to support the shaft."
He replaced the handlebar column,
retightened the studs, and reconnected
the brake and throttle levers. Then he
wheeled the mower unit into place, pivot-ing
its mounting bracket up to bolt it into
the wheel-less fork. "I leave the mud-guard
in place since it doesn't interfere
with mowing. The mudguards are merely
a standard bike fender cut in half."
With the inventor aboard, the little
tractor-mower moved out across a wide
stretch of grass, maneuvering around
several fruit trees and running close along
a hedge.
5. The dump cart. This time, when
the coupling pin was withdrawn and the
frame pulled apart, the front steering
column was discarded. Instead, a new
vertical column, welded into the frame of
a two-wheeled cart, was bolted onto the
fixed fork of the rear wheel. Only the back
half of the scooter is used in this conver-sion,
and the power wheel becomes the
front wheel of the cart tricycle—which is
steered by pivoting the entire power unit.

stand pivot. The cart bed is a simple
wooden box nested in an angle-iron frame
that's fastened to the wheelbase frame by
means of three pivot bolts. Biesecker re-leased
a spring catch and lifted the front
end of the box to show us how it dumped;
then he swung aboard the new seat and
headed the tractor into a potato patch. In
a moment he chugged back with a full
load. "It'll tote 500 pounds without strain.
Only trouble is, you get lazy," he called
as he passed on back toward the barn.
6. The snow plow. It was now time to
hook on the largest accessory. "A sheet-metal
shop cut and bent the blade for
me," Biesecker explained as he laid the
long frame flat on the slab floor. After
removing the pipe spacer between the top
ends of the notched uprights, he lifted
the tractor to swing it across and drop it
inside the frame's broadest opening. The
steering-column braces slipped down the
slot formed by the uprights.
With the spacer pipe bolted back in
place, Biesecker crawled beneath the cart
to raise the back of the plow frame and
bracket the upbent ends to the axle. Next,
settling himself on the seat, he reached
down between his thighs, gripped the
handles on the uprights, and hitched the
entire frame up until one of the notches
hooked onto a short length of rod welded
across the top brace. The plow frame and
blade now hung suspended, so that when
he started the motor he was able to drive
the whole assembly out of the barn. We
squinted up at the mild, cloudless sky.
"Last winter was great for plow-test-ing,"
Biesecker assured us, presenting a
snapshot to back him up. "My best trac-tion
is when my girl rides in the cart."
The demonstration was complete. But
it hadn't exhausted Biesecker's ingenuity.
As we tucked away note pad and cam-era,
he patted the transformed scooter
thoughtfully. "This is only as far as I've
gone," he announced. "I'm now working
on a couple of collapsible pontoons and
a propeller drive. So this summer, when
I ride the scooter up to the lakeshore,
I'll just keep on going. And"—his eyes
lifted, focusing somewhere out in space—
"maybe . . . souped up a little and
equipped with rotor blades . . . it'll lift
right off the ground . . ."
We fled.
