The Rite 750 Earthquake was the highest-output tractor produced by Rite Tractors. It represented the upper limit of the company’s articulated four-wheel-drive tractor program and was built for large-scale primary tillage.
The model followed the same low-volume, build-to-order philosophy used across the Rite product range. Specifications could vary, but the core layout and powertrain concept remained consistent.
About Rite Tractors Brand
Rite Tractors focused exclusively on high-horsepower articulated machines. Model names were typically based on approximate engine output rather than series or generation structure.
Other known Rite models included:
- Rite 303
- Rite 404
- Rite 470
- Rite 505
- Rite 606
- Rite 707
These tractors shared a similar design approach, including articulated frames, equal-size wheels, and industrial diesel engines. The Rite 750 Earthquake sat at the top of this lineup.
Engine and Powertrain
The standard Rite 750 Earthquake was powered by a Detroit Diesel V12 engine.
- Engine type: Detroit Diesel V12.
- Displacement: 18.1 liters (1,104 cubic inches).
- Engine design: two-stroke diesel.
- Rated output: approximately 750 horsepower in standard configuration.
Some units were later modified or uprated by owners, but the standard production configuration was rated at approximately 750 hp.
Power was delivered through a heavy-duty drivetrain designed for continuous drawbar load. The tractor used full-time four-wheel drive and an articulated center joint.
Chassis and Layout
The Rite 750 used an articulated frame with equal-diameter wheels front and rear. This configuration supported traction and weight distribution under heavy draft conditions.
- Drive type: articulated 4WD.
- Steering: center articulation.
- Tire size commonly reported: 35.5L32.
The tractor was intended for operation with very large tillage implements, including multi-bottom moldboard plows.
Dimensions and Weight
Published dimensional data varies slightly between sources, reflecting individual build differences.
Commonly cited figures include:
- Operating weight: approximately 31–32 metric tons.
- Overall length: approximately 9.1 meters.
- Overall width: approximately 5.4 meters.
- Overall height: approximately 4.2 meters.
Exact measurements depended on tire configuration and ballast.
Production Years
The Rite 750 Earthquake was produced during the late 1970s and early 1980s. Rite Tractors did not operate on fixed model-year cycles, and production dates were not formally published.
Assembly occurred on a per-order basis rather than in continuous series production.
How Many Rite 750 Tractors Were Made
The exact number of Rite 750 Earthquake tractors built is not documented in factory records available to the public.
Based on collector records, trade publications, and historical references, it is generally accepted that only a very small number were produced, likely single digits to low double digits.
This aligns with the overall Rite production approach, where total brand output across all models is estimated at several dozen tractors.
Use and Historical Position
The Rite 750 Earthquake was designed for large farms requiring extreme draft capability. It was not intended for transport-focused or mixed-use farming.
Today, the model is primarily seen at tractor shows and field demonstrations. It is frequently referenced in discussions of the largest agricultural tractors ever built due to its engine size and rated output.
