ENGINE DETAIL
The Heider C 15-27 tractor features a robust Waukesha liquid-cooled 4-cylinder engine with a significant displacement of 478 ci (7.8 L), providing ample torque for heavy-duty agricultural tasks. Its relatively low rated RPM of 900 suggests a focus on high torque at low speeds, ideal for plowing or pulling applications, but may limit speed for transport activities. The coolant capacity of 36 quarts (34.1 L) is essential for maintaining optimal operating temperatures during prolonged use, which is critical for preventing overheating in demanding conditions.

HEIDER C 15-27 ENGINE
The Heider C 15-27 is equipped with a Waukesha 7.8L 4-cylinder kerosene engine, providing efficient fuel combustion for increased power output in agricultural applications. With a 21-gallon (79.5 L) fuel tank, it offers extended operation time, beneficial for long working hours in the field. However, kerosene may be less readily available in some regions compared to diesel, posing a potential challenge for users.

TRANSMISSION
The Heider C 15-27 tractor features an unsynchronized gear system with a total of 7 forward and reverse gears, which allows for straightforward operation but may present challenges in shifting under load. This unsynchronized mechanism can lead to increased wear over time and may require more driver skill to avoid grinding gears. Best suited for applications where ease of use is prioritized over high-speed operation, this tractor is ideal for tasks such as tilling or hauling in low to moderate speed conditions.

| Gears | 7 forward and reverse |
MECHANICAL
The Heider C 15-27 features a 4x2 2WD chassis, which provides basic traction suitable for light agricultural tasks but may struggle in muddy or uneven terrain. Its manual steering system can enhance driver control, yet requires more physical effort compared to power steering options. The 7-speed unsynchronized transmission offers flexibility in speed adjustments, though it may present challenges in smooth gear shifts, particularly for less experienced operators.

HEIDER C 15-27 TIRES
The Heider C 15-27 tractor features 30x5 steel ag front wheels and 57x10 steel ag rear wheels, providing robust load-bearing capacity and traction in various agricultural scenarios. The larger rear wheels enhance stability and performance in fieldwork, but may pose challenges in tighter spaces due to increased turning radius. Maintenance of steel wheels is crucial for longevity, as they can be prone to rust and wear if not properly cared for.
| Ag front | 30x5 steel |
| Ag rear | 57x10 steel |

DIMENSIONS & TIRES
The Heider C 15-27 tractor features a wheelbase of 96 inches (243 cm), which contributes to its stability in both field and transport applications. The front tires measuring 30x5 offer good maneuverability, while the large rear tires at 57x10 provide enhanced traction and weight distribution, crucial for handling heavier loads and reducing soil compaction. However, bear in mind that the tire sizing may impact turning radius in confined spaces, making it less suited for tight quarters.
