ENGINE DETAIL
The Avery 20-35 tractor features a robust 4-cylinder opposed horizontal engine with a significant displacement of 522.6 ci (8.6 L), providing ample torque for agricultural applications. With a bore of 4.875 inches and stroke of 7.00 inches, it offers a characteristic low-RPM performance of 900, which is advantageous for heavy-duty tasks but may limit maximum speed. Using kerosene as a fuel can lead to higher operational costs and maintenance considerations, especially in comparison to modern gasoline or diesel alternatives, impacting its feasibility for contemporary agricultural operations.

AVERY 20-35 ENGINE
The Avery 20-35 tractor features an 8.6L 4-cylinder kerosene engine, providing robust torque suited for heavy-duty applications. With a 30-gallon main fuel tank and a 3.5-gallon auxiliary tank, operators benefit from extended operational range, ideal for extended fieldwork without frequent refueling. However, the utilization of kerosene may require specialized starting procedures and fuel management practices, which could pose initial challenges for equipment operators.

TRANSMISSION
The Avery 20-35 tractor's transmission provides a basic gear setup with only 2 forward and 1 reverse gear, which limits its speed versatility and operational efficiency. This simple gearing could be advantageous in specific applications like light agricultural tasks or small property maintenance where high-speed operation is not critical. However, for more demanding tasks requiring varied speed or heavy-load transportation, this limited gearing may pose challenges in maneuverability and performance.

MECHANICAL
The Avery 20-35 tractor features a 4x2 2WD chassis, which provides basic maneuverability but may have limitations in traction on challenging terrains. The 2-speed transmission offers versatility for different field operations; however, it may not provide the range or efficiency of more advanced multi-speed or hydrostatic systems. This setup is ideal for light to moderate agricultural tasks but may struggle in heavy-duty applications or hilly environments.

AVERY 20-35 TIRES
The Avery 20-35 tractor features agricultural front wheels sized 36x6 inches, which enhance maneuverability in tight farm spaces, while its rear wheels, sized 60x16 inches, provide improved traction and stability for heavier loads. The use of steel for both front and rear wheels offers durability and resistance to wear, although it may result in a heavier overall weight affecting compaction in soft soils. This tractor is ideal for medium-duty tasks, but operators should be cautious when working in wet conditions to avoid soil disruption.

DIMENSIONS & TIRES
The Avery 20-35 tractor, weighing 7,500 lbs (3,402 kg) with front tires sized 36x6 and rear tires 60x16, boasts a robust configuration suitable for medium agricultural tasks. The larger rear tires provide enhanced traction and stability, advantageous for plowing or heavy hauling. However, the overall weight may challenge maneuverability in tight spaces, making it less ideal for smaller farms or gardens.
