Introduction
Heider Model B Agricultural Tractor
The Heider Model B is a standard-tread tractor manufactured in Carroll, Iowa, USA, produced between 1911 and 1914. This early agricultural machine was designed to provide mechanical power for field operations during the transition to mechanized farming.
Engine and Cooling
The tractor is powered by a Waukesha liquid-cooled engine designed to operate on kerosene. The engine features a bore and stroke of 4.25 by 6.75 inches and is supported by a cooling system with a capacity of 40 quarts (37.9 liters). It is rated at 800 RPM.
Transmission and Drivetrain
The Heider B utilizes a friction drive transmission, which allows for infinitely variable speed control. The system functions by sliding the engine to adjust the contact point between the flywheel and the driving discs. While the design allows for any speed, the operator interface includes seven notches, providing seven forward and reverse speeds. The tractor is configured as a two-wheel drive unit with manual steering.
Performance and Capacity
The tractor is rated for a drawbar power of 10 hp (7.5 kW) and a belt power of 20 hp (14.9 kW), with a total engine rating of 22 hp. It is engineered to pull a four-bottom plow, making it suitable for primary tillage tasks of its era.
Dimensions and Build
The machine has a length of 144 inches (365 cm), a width of 74 inches (187 cm), and a height of 96 inches (243 cm). With a curb weight of 5,800 lbs (2,630 kg), it provides the necessary mass for traction. The unit includes a four-post canopy for basic operator coverage.
Conclusion
The Heider Model B represents a notable example of early 20th-century American agricultural engineering. Its friction drive transmission offered a distinct approach to speed regulation, positioning it as a versatile implement for farmers requiring consistent power for plowing and belt-driven stationary work.

Transmission Information of Heider, B
Transmission variants 1
- The Heider friction drive transmission was an infinitely-variable transmission. Speed was selected by sliding the entire engine, which changed the contact point between the flywheel and the driving discs. Although any speed was possible, there were seven notches for the lever, effectively giving seven speeds.
