ENGINE DETAIL
The Farmall Hydro 100 features a powerful 7.1L, 6-cylinder diesel engine with a high compression ratio of 15.8:1, enabling efficient fuel combustion and effective power delivery at a rated RPM of 2400. Its dual-stage dry air cleaner enhances air intake efficiency while minimizing engine wear in dusty conditions. However, the relatively large displacement may present challenges in maneuverability in tight spaces, making it better suited for extensive agricultural operations than small-scale tasks.

TRANSMISSION
The Farmall Hydro 100 features a hydrostatic transmission, allowing for seamless speed adjustments without shifting gears, ideal for precise maneuvering in complex farm environments. Its infinite forward and reverse range enhances operator flexibility, making it beneficial for tasks like loader work or tillage. However, hydrostatic systems can be less efficient at powering through heavy loads compared to traditional mechanical transmissions, which may be a consideration for certain agricultural applications.

MECHANICAL
The Farmall Hydro 100 features a 4x2 2WD chassis which provides simplicity but may limit traction on uneven terrain compared to 4WD options. Its hydrostatic power steering enhances maneuverability, making it ideal for precision tasks in tight spaces, while the differential hydraulic dry disc brakes ensure reliable stopping power. The open operator station offers good visibility, but may expose the operator to environmental elements, making the optional cab desirable for comfort and protection in adverse weather conditions.

FARMALL HYDRO 100 TIRES
The Farmall Hydro 100 tractor is equipped with Ag front tires (10.00-16) and larger Ag rear tires (18.4-34), which enhance traction and stability during field operations. The hydrostatic transmission provides seamless speed control, improving maneuverability on varied terrain. However, the larger rear tires may challenge tight cornering in smaller fields, making it more suited for expansive agricultural operations.
