ENGINE DETAIL
The Heider B tractor features a liquid-cooled Waukesha engine, ensuring efficient thermoregulation for optimal performance. Its 4.25 x 6.75 inch bore and stroke create a displacement that supports robust torque at a rated RPM of 800, making it suitable for heavy-duty tasks. The 40-quart coolant capacity aids in extended operation under load, but potential challenges may arise in maintaining coolant levels and system integrity for longevity.

HEIDER B ENGINE
The Heider B tractor powered by a Waukesha kerosene engine offers a substantial fuel capacity of 26 gallons (98.4 liters), which is advantageous for extended operational periods without frequent refueling. Its kerosene engine provides potentially lower emissions compared to gasoline but may present challenges in terms of fuel accessibility and handling. In scenarios where high torque is required, the engine's performance characteristics, including fuel efficiency and power delivery, should be thoroughly evaluated to match the intended agricultural applications.

TRANSMISSION
The Heider B tractor features a unique friction drive transmission that allows for infinitely-variable speed selection by sliding the engine to adjust the contact point between the flywheel and driving discs. This design provides versatility with seven distinct notches, enabling the operator to fine-tune speed efficiently across various operational scenarios. However, challenges with wear and maintenance may arise due to the friction nature of the system, which could impact long-term reliability compared to traditional gear systems.

| Description |
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. |
MECHANICAL
The Heider B tractor features a 4x2 2WD chassis, providing moderate traction suitable for flat terrains but limiting performance in more challenging conditions. The manual steering can enhance operator control, though it may require more effort during tight maneuvers. The 7-speed friction drive transmission offers versatility in speed selection, advantageous for varying tasks, but may present maintenance challenges due to friction wear over time.

DIMENSIONS & TIRES
The Heider B tractor, weighing 5,800 lbs (2,630 kg), offers a heavy-duty build ideal for pulling and tilling operations, enhancing soil aeration and crop yield. Its weight can provide stability on uneven terrain, but may limit maneuverability in tighter spaces. Consideration of soil compaction is essential; heavier tractors can lead to adverse effects on soil health if not managed properly.
