ENGINE DETAIL
The White 185 tractor is powered by a CDC-Cummins turbocharged diesel 6-cylinder engine, providing robust torque suited for heavy-duty applications, thanks to its 8.3L displacement and a compression ratio of 16.5:1. The direct injection fuel system enhances fuel efficiency and performance, while the dual paper element air cleaner ensures optimal air intake and engine longevity. Challenges may arise during maintenance due to the relatively high oil and coolant capacities (23.5qts and 26.6qts respectively), necessitating careful monitoring to prevent overheating or lubrication issues during extended operation.

WHITE 185 ENGINE
The White 185 tractor is powered by a CDC-Cummins 8.3L 6-cylinder diesel engine, which provides robust performance with high torque output, making it well-suited for heavy-duty tasks in agricultural applications. However, the engine's larger displacement may lead to higher fuel consumption compared to smaller engines, thus requiring careful cost-analysis on fuel efficiency versus power needs. A potential advantage of this model is its durability and reliability, beneficial in demanding conditions, but owners should keep in mind the maintenance complexity associated with larger diesel engines.

TRANSMISSION
The White 185 tractor features a partial powershift transmission with 18 forward and 6 reverse gears, providing enhanced flexibility in various field operations. The 355.6mm dry disc clutch offers robust engagement but may require more maintenance compared to hydraulic clutches, especially under heavy loads. This tractor is well-suited for tasks like plowing or hauling where precise speed control and torque management are essential, but operators should be aware of the potential for higher wear on the dry disc system.
| Transmission | 3x6 Over/Under |
| Type | partial powershift |
| Gears | 18 forward and 6 reverse |
| Clutch | 355.6mm dry discs |
| Description | Six forward and two reverse gears with an over and under powershift for each gear. |
MECHANICAL
The White 185 tractor features a versatile drivetrain with options for both 2WD and 4WD, enhancing traction and stability across varying terrain conditions. Its 18-speed partial powershift transmission allows for smooth gear transitions, optimizing power delivery during operations, while the independent hydraulic wet disc brakes provide effective stopping power even in demanding circumstances. However, the reliance on planetary final drives may raise maintenance considerations, especially when frequently operating in rough conditions; ensuring consistent lubrication is critical for longevity and performance.

WHITE 185 TIRES
The White 185 tractor features agricultural front tires sized 14L-16 and rear tires sized 20.8R-38, optimizing traction and stability for various farming applications. The larger rear tires enhance load-bearing capacity and improve ground engagement, making it suitable for pulling heavy implements. However, the relatively smaller front tire size might limit front-end stability under heavy loads or steep inclines, which should be considered during operation.

DIMENSIONS & TIRES
The White 185 tractor's 2WD configuration with a 112-inch wheelbase provides enhanced stability and load distribution, ideal for agricultural tasks requiring consistent traction. Its weight range of 13,600 to 17,150 pounds allows for significant pulling capacity, but may limit mobility in softer terrains; this is mitigated in the 4WD variant with a shorter 90-inch wheelbase, enhancing maneuverability in challenging conditions. Proper tire selection, with front 14L-16 and rear 20.8R-38 sizes, can optimize performance, but may require careful monitoring of inflation pressures to maintain efficiency and reduce soil compaction.
