Part Identification:
Primary function is the identification of all replaceable parts with corresponding part numbers and diagrams.
Assembly Overview:
Illustrates how various sub-assemblies are put together by listing individual components.
Part Ordering Guidance:
Provides essential part numbers required for ordering replacements from authorized dealers.
Depth Of Coverage:
Highly detailed, focusing on every nut, bolt, washer, and specialized component of the tractor.
Diagnostic Utility:
Indirectly aids in diagnostics by helping to identify faulty components based on their visual representation and assembly location.
Repair Assistance:
Essential for accurate reassembly after repairs or component replacement by ensuring the correct parts are used.
Engine Manufacturer:
Likely sourced from established diesel engine manufacturers (e.g., Perkins, Waukesha, or an in-house White engine).
Engine Type:
Diesel (typically naturally aspirated or turbocharged inline 3 or 4-cylinder)
Displacement:
Typically in the range of 2.5 to 4.0 liters, depending on specific engine variant.
Horsepower Rating:
Nominal 75 PTO horsepower (PTO HP is the standard metric for tractor engine power output). Drawbar horsepower (DBHP) would be slightly lower.
Torque Curve:
Designed for strong low-end torque, essential for pulling implements in agricultural applications.
Injection System:
Likely mechanical inline injection pump and injectors.
Transmission Type:
Constant Mesh Gearbox with synchronized shifting (common for the era) or a partial power shift transmission.
Gear Configuration:
Multiple forward and reverse gears (e.g., 12 forward x 4 reverse or similar).
Optional Transmission:
Some models may have offered a creeper gear option or a shuttle shift (forward/reverse reverser) without a clutch pedal.
Pto Options:
Standard 540 RPM and potentially 1000 RPM PTO options, driven by a dedicated PTO clutch.
Wheelbase:
Variable, but typically around 85-95 inches for this class.
Overall Length:
Approximately 140-155 inches (without implement).
Overall Width:
Approximately 70-80 inches (depending on rear tire size and tread setting).
Ground Clearance:
Variable, typically 15-20 inches under the rear axle.
Operating Weight:
Around 5,000 - 6,500 lbs (unballasted).
Max Allowable Weight:
Can be significantly increased with front and rear ballast for stability.
Rollover Protection:
ROPS (Roll Over Protective Structure) likely standard or a common option for this era.
Braking System:
Wet disc brakes or dry disc brakes, providing reliable stopping power.
Operator Station Design:
Designed with operator comfort and safety in mind, including access steps and handrails.
Operator Interface:
Basic mechanical controls, gauges for engine RPM, temperature, oil pressure, fuel level, and battery voltage. No modern infotainment systems.
Guidance Systems:
None inherent; aftermarket guidance systems could be retrofitted.
Digital Features:
None; this is a mechanical agricultural tractor from an era predating widespread digital integration in machinery.
Engine Oil Change:
Typically every 100-250 operating hours or annually, depending on usage severity.
Hydraulic Fluid Change:
Recommended every 500-1000 operating hours, including filter replacement.
Engine Oil Type:
API CD or CE rated Diesel engine oil, viscosity typically SAE 15W-40 or 30W depending on climate.
Hydraulic Fluid Type:
Tractor Hydraulic Fluid (THF) or a compatible universal tractor transmission fluid (UTTF), or SAE 20W-30 depending on manufacturer specification.
Transmission Fluid Type:
EP (Extreme Pressure) Gear Oil, SAE 90 or 80W-90, or specialized transmission fluid as per OEM specification.
Coolant Type:
Ethylene Glycol based coolant with appropriate anti-corrosion additives, mixed 50/50 with distilled water.
Common Wear Items:
Clutch wear, hydraulic pump performance degradation, PTO clutch wear, seal leaks (engine, transmission, hydraulics), and electrical component corrosion are common for tractors of this age.
Maintenance Challenges:
Availability of certain specialized parts may be limited; thorough part identification via this manual is critical.
White Farm Equipment History:
White Farm Equipment was a significant American agricultural machinery manufacturer, known for its robust and reliable tractors, eventually becoming part of AGCO Corporation.
Field Boss Series:
The 'Field BOSS' line represented a strong offering in White's utility tractor range, designed for broad agricultural applications.
Production Period:
Likely produced in the late 1970s to early 1980s, a period of significant technological advancement in tractor design.
