UPTON 180 POWER
ENGINE DETAIL
The Upton 180 tractor features a robust Nissan UD43 two-stroke diesel engine, providing 180 hp and a substantial torque of 458 lb-ft at 1400 RPM, making it well-suited for heavy-duty agricultural applications. With a 302 ci (4.9 L) displacement and a high compression ratio of 16:1, this engine offers efficient power delivery and responsiveness, although two-stroke engines can be less fuel-efficient than their four-stroke counterparts. Its lower RPM rating of 2400 may limit maximum speed but enhances low-end torque, beneficial for tasks requiring high pulling power, such as plowing or hauling heavy loads.

UPTON 180 ENGINE
The Upton 180 tractor, powered by a Nissan 4.9L 4-cylinder diesel engine, offers robust torque and fuel efficiency, ideal for heavy-duty agricultural tasks. Potential challenges may include the engine's weight affecting maneuverability and maintenance costs associated with the diesel system. In scenarios requiring sustained power for plowing or hauling, the engine's displacement provides an advantage, ensuring optimal performance and longevity.

TRANSMISSION
The Upton 180 tractor features a versatile transmission configuration with 21 forward and 9 reverse gear combinations, enhancing its adaptability in various terrains. Utilizing military-surplus gearboxes, including a Spicer rear gearbox from the LVT-4 and later Mack gearboxes from the M3 tank, it benefits from robust engineering and durability. However, reliance on surplus components may pose challenges in parts availability and maintenance, potentially affecting long-term operational efficiency.
| Gears |
21 forward and 9 reverse |
| Description |
The Upton 180 used military-surplus gear boxes. The first gearbox offered four-forward and one-reverse speed. The second gearbox offered five-forward and one-reverse gear. This arrangement offered 21 forward and nine reverse gear combinations. The original rear gearbox was a Spicer from the LVT-4 landing craft. Later, Mack gearboxes from the M3 tank were used. |
MECHANICAL
The Upton 180 tractor features a 4x2 2WD chassis, offering sufficient traction for flat terrain, but may struggle in adverse conditions like mud or hills due to its lack of all-wheel drive. Its 21-speed transmission allows for precise speed control across various tasks, enhancing versatility in applications from fieldwork to transport. However, operator familiarity with complex gear shifting may be necessary to fully leverage its capabilities, which can pose a learning curve for less experienced users.

UPTON 180 TIRES
The Upton 180 tractor features agricultural (Ag) tires with a front size of 11.00x16 and rear sizes of 18.4x34 or 18.4x38, providing a solid balance of flotation and traction for varied soil conditions. The larger rear tires enhance stability and pulling power for heavier implements, making the tractor suitable for field work and transport in agricultural applications. A potential challenge is the limited maneuverability due to the tire size; hence, tight spaces may require careful navigation.

DIMENSIONS & TIRES
The Upton 180 tractor's significant weight of 18,500 lbs provides excellent traction but may limit mobility in muddy or soft conditions. The front tires (11.00x16) facilitate steering stability, while the larger rear tires (18.4x34) enhance field capability and load-carrying capacity. This configuration is ideal for heavy-duty agricultural applications, though it may require appropriate loading equipment for transport and maneuverability.
