REO LAWN MOWERS

This
is an advertising pamphlet for REO Mowers. The name REO
represents the initials of Ransom Eli Olds, who was involved in many
enterprises in and around Lansing, Michigan. He founded the Olds
Motor Works and Reo Motors, and was part owner in a number of other
companies which were involved in trucks, automobiles, and engines.
These companies include Olds Gas Power Company, Original Gas Engine
Company, and Ideal Motor Company, which built stationary engines.
Ransom Olds died in 1950, at the age of 86, but was no longer connected
with any of these companies.
Reo Motors became well-known for its trucks, and supplied many trucks
and engines for the US military during World War II. Following
the post-war boom, truck sales slowed down drastically in early 1949,
but three years earlier the company had started building gas
engine-powered lawn mowers. This lawn mower division helped the company
survive during this time.
Joseph S. Sherer, Jr. was president of Reo Motors at the time the lawn
mower line was started. Mr. Sherer was a graduate of MIT and was
formerly Vice-president and General Manager of Ideal Lawn Mower Company
of Lansing. He brought several engineering and sales people with
him from Ideal.
Reo started the Lawn Mower Division in 1946 with a 17-inch push-type
mower, and a 21-inch engine-powered reel-type mower. At this time
Reo was using Clinton and Briggs & Stratton engines, but engineer
Francis Korff was busy developing Reo's own engine in their engineering
lab. That engine was introduced in 1949, and became a great
success. It was a well-built cast iron engine, with its cylinder
head slanted at 45 degrees. It ran backwards, viz.,
the flywheel rotated counter-clockwise, which was opposite from most
other small engines. Interestingly, the power was taken from the
camshaft, resulting in the drive pulley turning in the same direction
as other engines, at half of the crankshaft speed. The intake and
exhaust valves were both operated by a single cam lobe on the
camshaft. A variation of the basic engine with a 6:1 gear
reduction was used on their deluxe lawn mower, the Trimalawn, and was
also used on a snow blower several years later.
Reo also made an item called the Trollabout, which was made for
installation in a rowboat. The standard Reo mower engine was
mounted on a slightly tilted platform inside the boat, and a power
shaft went through the bottom of the boat to drive an aluminum prop -
the common man's inboard-outboard The introduction of the
Trollabout did not go well. One of the company officials who was trying
to promote it had called newspapers and radio stations to demonstrate
it. Someone had apparently done a poor job of installing the
Trollabout, and had not caulked properly around the hole where the prop
shaft went through the bottom of the boat. Right in front of everybody,
the boat sank That might just explain why the product was
never very popular.
During the post-war era the power mower was in great demand. By
1950, REO had become the largest manufacturer of power mowers in the
world, with sales that year of almost 10 million dollars. Mower number
500,000 was produced in 1951; daily production at that time was about
1,000 units a day.
However, REO made an error during this time which would drastically
hurt their sales within the next few years. The mower industry
was rapidly changing to the rotary-blade mower, which was much cheaper
to produce (and easier to operate) than the reel-type unit which REO
continued to manufacture.
Finally, in 1953, REO did make an attempt to market a rotary mower, but
their design was a disaster, to say the least. Rather than
building an engine for their Flying Cloud rotary with a vertical
crankshaft, REO engineers added a separate vertical shaft alongside the
engine, driven off the camshaft with a set of bevel gears. This
shaft was connected directly to the blade on some models, while another
model called Flying Cloud used a V-belt from this shaft to another jack
shaft that drove the blade. There were a number of problems with
this design, outlined in service bulletins for the Flying Cloud.
The worst problem was with a thrust washer that was mounted on that
vertical shaft in the engine. In some engines this washer would
start rotating with the shaft, and chew up the gear housing. This
resulted in ground-up metal entering the crankcase, and before the
customer knew it his engine was shot. Correction of the design
was simple - a tab was added to the washer to keep it from
rotating. Correcting all the problems for their customers was
much more costly, however. According to Don Houghtaling, REO
Service Manager, this little washer cost them over 5000 replacement
engines.
In September, 1954, REO sold their lawn mower division to Motor Wheel
Corporation of Lansing, a major manufacturer of automotive and
agricultural wheels. Motor Wheel continued the REO line alongside
their Duo-Therm Division, which manufactured home space heaters.
In 1955 the REO engine was finally released in a true vertical shaft
version. The engine was laid on its side, the flywheel, coil and
points were moved to the opposite end of the crankshaft. The
flywheel now rotated clockwise, like most other engines. This
vertical shaft version was used for three years. By this time
Power Products Company had convinced Motor Wheel that they could buy
their Tecumseh engines for less cost than building their own
engine. Beginning in 1958 Motor Wheel bought all their vertical
shaft engines from Tecumseh/Power Products. The Tecumseh name did
not appear on the engines; they were labeled as the REO Raider
Engine . The REO slant-head engines were still used in 1958. on the
deluxe reel-type mower and snow blower. Then, these were also
converted to Tecumseh engines. Thus ended the 10 year history of
the unique REO slant-head engine that ran backwards .
In September, 1963 Motor Wheel Corporation sold their entire REO line
to Wheel Horse Products in South Bend, Indiana. Wheel Horse
continued the REO line for several years, selling a riding lawn mower,
snow blower, and some rotary mowers with the REO name.
Ultimately, Wheel Horse dropped the REO name from its product line.
