Minneapolis-Moline
G-1000 Series Tractor
By Jim Janssen
My name is Jim Janssen. I worked for Minneapolis-Moline from 1950
to its demise in 1971, starting out in the branch sales office in
Hopkins, Minnesota. Then I was a blockman at Willmar, Minnesota and
later sales manager at the Fargo, North Dakota and Kansas City, Kansas
branches. After that, I became branch manager at Peoria, Illinois
and from there went to Omaha, Nebraska as western regional manager
for White Farm Equipment from 1972 to 1989. Thus, I've had quite
a bit of experience in the United States west of the Mississippi
River.
After reading an ad in the Prairie Gold Rush tractor magazine
asking for someone with knowledge of Minneapolis-Moline Co. and
its products, I contacted Richard Hain and he suggested I write about
products in the 1960-1990 period. Since Minneapolis-Moline became
White Farm Equipment in 1972, I chose the G-1000 series since it
was very popular in the area I worked and therefore I had a lot
of
experience with it.
The G-1000 was the first 100 horsepower plus
row crop tractor to come to the United States market. It was
introduced in the spring of 1965. The first production of just over
100 units
was sold to a select group of farmers all over the United States.
They agreed to keep records of its performance in all areas and
report back to Minneapolis-Moline engineering and sales people.
Their suggestions
and complaints were all reviewed by Minneapolis-Moline and the
first full production was planned for the winter of 1965-66. One
of the
original purchasers of the test tractor was Wayne Kennedy of
Kimball, Nebraska. He liked it so much that he bought four more in
the next
two years. He bought these five tractors from the dealer, Foland
Farm Machinery at Sidney, Nebraska.
I met Mr. Kennedy in the
'70s when I was working out of Omaha. Prior to the tractor's production,
dealer meetings were held in all branches to acquaint the Minneapolis-Moline
dealers with all the facts and figures on this new model. This
was the biggest and most extensive introduction the company had
ever
done on any one single piece of equipment. The main features
of this
first 110 horsepower row crop tractor were as follows:
1. The whole
purpose of this tractor was ?built for those who farm big.?
2.
It was built in both diesel and LP-gas models with a few gasoline
models
available in the initial production. (These really ate the fuel.)
3. The 504 cubic inch engine produced 111.00 horsepower in the
diesel version and 110.76 in the LP-gas version. These were both
PTO horsepower
(Nebraska test number 954-974-975). Other tractors in this
class had engines of 301 to 404 cu.in.
4. This horsepower on both
models
was developed at 1800 RPM. Other tractors in this class ran
at 2000 to 2400 RPM.
5. The tractor had only a 20 inch wide frame
to giver
the operator maximum visibility and maneuverability. 6.
The final
drives were much heavier than in previous tractors such
as the G-VI. Minneapolis-Moline engineers finally learned that you
can't have
100 plus horsepower up front and final drives from 80 horsepower
units.
7. The 504 cubic inch engine was six cylinders with blocks
cast in pairs with a heavy cast iron oil pan and three main bearings
crankshaft.
8. The G-1000 had a basic five speed transmission
with two speeds in each gear. This shift on the go was called ?ampli
torc.? It gave a 25 to 30 percent reduction in each gear, providing
speeds
of 2.25 mph to 18.05 mph in forward and 1.86 mph to 3.57 mph
in
reverse.
9. The weight of the tractor was 10,1000 pounds (diesel)
and 10,
250 pounds (LP) with no extra equipment. This was about 1,500
pounds heavier than other tractors in its class. 10. The turning radius
was 12 feet, 3 inches without brakes and fuel capacity was 40
gallons (diesel) and 39 gallons (LP).
11. The tractor came standard
with
both 540 and 1000 RPM PTO shafts. You could just hook up to
the shaft that fit your implement.
12. The hydraulic system was a 9 cylinder
Vickers piston pump which supplied the power to the power steering
and draft sensitive three-point hitch and remote hydraulics. This
system was much improved over earlier models.
13. The tractor was
easy to service. Hood and grills could easily be removed by toggle
latch and quarter-turn fasteners.
14. The G-1000 was also available
in a Wheatland version. This is a fixed front I-beam axle and
no three-point hitch, just remote hydraulics.
15. The G-1000 had tremendous
pulling power. The 1800 RPM 504 cubic inch engine gave it a drawbar
pull of 14,443 pounds at 2.22 mph. Compare this to a JD 4020
at 11,249 pounds at 2.63 mph.
16. The tractor was priced correctly as
the G-1000
diesel had a list price $8,882 FOB factory. This was up to $1,000
less than comparable models even though they had 15-20 less PTO
horsepower.
In late 1967, a new model G-1000 was introduced as the
G-1000 Vista. It was basically the same tractor as the G-1000 except
it had a higher
operator's platform and more convenience operator controls. Operators
really liked this high platform as it gave them great vision and
was up and out of the dust. A disadvantage of this raised platform
was that it covered up all the hydraulic lines so if they had to
be worked on, it was quite a job. It also had a larger diesel fuel
tank (56 rather than 40 gallons). The Vista went back to the original
Minneapolis-Moline color of ?prairie gold,? not yellow and brown
as previous tractors had been since about 1963.
The G-1000 Vista
was also available as a wheatland and row crop model. Both were
available with full time power front axle. Minneapolis-Moline was
a pioneer
in the use of power front axles on tractors. It also was available
with a three speed ample torc which gave it 15 forward speeds and
three reverse speeds. A factory installed cab was also available
for $995. The g-1000 Vista was produced until 1969 when it was
replaced by the G-1050.
In summary, the G-1000 and the G-1000 Vista
were very
powerful tractors, comfortable to operate and had a long life
with a minimum or troubles. On the first and second production of
G-1000s,
purchasing changed to a different rear axle bearing without telling
engineering. These bearings failed in some cases and caused ring
gear and pinion failure. As soon as this was discovered, the
company had a program to change these bearings. Competition got wind
of
this and said it was a poor ring gear and pinion. The word got
around and it certainly didn't help the G-1000 reputation. In retrospect,
though, there were very few rear end failures in the G-1000 where
the bearings were changed. These tractors today, even though they
are 35 years old, command a good price and still good a job for
the
owner at a very reasonable upkeep cost. They were built for those
who farm big and are still doing it. Total production of these
two models was 7,397. This is small compared to the numbers of John
Deere
and IH, but one must remember that most of the MM tractors were
sold in states west and south of Minnesota. Total tractor sales in
this
area was not as large as in the corn belt and east, so the MM sales
in this horsepower class were about eight to 10 percent of the
market.
Another feature of these two tractors was that dealers discovered
you could install the MM HD 800 cubic inch engine in these models
without too much expense. Of course, the HD 800 engine was only
available
in LP or natural gas but when installed, it was hard to beat
for power. By adding turbo chargers and speeding up the engine RPM,
you could get up to 600 to 700 horsepower. To do this, the engine
parts
all had to be balanced. MM built a G-1000 Vista with a turbo
charger
and balanced HD 800 engine while I was in Peoria. We took this
to the Louisville Tractor Pull in 1969 and won first place by quite
a margin.
I worked with a farmer in Atwood, Illinois who ha three
G-1000 Vistas with standard HD 800 engines'that is, no turbo
chargers and running at 1800 RPM. He started with just one unit but
liked
it so much he had two more built by the dealer. In 1969, to have
a 200 plus horsepower tractor was something, as this owner stated: "I always wanted a tractor that if I wanted to go slower, I throttled
back and if I wanted to go faster, I throttled up without shifting
regardless of the load I was pulling."
White Motor Co., which owner
Oliver since 1962 and Minneapolis-Moline since 1963, decided
in 1970
to discontinue both brands and start White Farm Equipment co.
This was the end of the low RPM high torque MM engines. White Motor
Co. did not believe in building engines. Their theory was to
buy
them.
They used purchased engines on all their tractors from this
period on. Possibly this was the way to go as the Cumming engines
used
in the later White tractor proved very successful in horsepower,
fuel economy and long life. That is another story.
