Horsepower Range:
Approximately 45-60 PTO horsepower, varies by engine and transmission configuration.
Injection System:
Direct injection, typically with rotary or inline fuel injection pumps.
Oil Type:
API CG-4 or CD/CE specification diesel engine oil (e.g., 15W-40) is commonly recommended for this era of tractor. Specific viscosity may vary by climate.
Type:
Manual Transmission (e.g., 8-speed or 12-speed constant mesh gearbox, often with multi-speed PTO)
Type:

Pto Speed:
Standard 540 RPM PTO, with potential for 1000 RPM PTO on certain configurations.
Gear Selection:
Confirms detailed procedures for shifting and gear engagement/disengagement.
Transmission Oil Type:
Massey Ferguson special tractor oil (e.g., MF Permatran U or equivalent Universal Tractor Transmission Oil - UTTO). SAE 10W-30 or 80W-90 may be specified depending on the transmission and operating temperature. Always refer to the specific manual for the exact specification.
Wheelbase:
Approximately 77-82 inches (1955-2083 mm), varies by model variant.
Length:
Approximately 120-135 inches (3048-3429 mm) without implements.
Operating Weight:

Brake System:
Internal expanding shoe brakes, serviced via pedals with interlock mechanism.
Operator Station:
Focus on safe operation, control identification, and emergency stop procedures.
Engine Oil And Filter:
Typically every 100-250 operating hours, or annually. Specific interval depends on oil type and operating conditions as per manual.
Transmission Hydraulic Filter:
Typically every 250-500 operating hours or annually. Fluid change intervals will also be specified.
Air Filter:
Check and clean every 50-100 hours, replace as needed. Dry element replacement is critical for engine longevity.
Coolant:
A mixture of ethylene glycol antifreeze and water (50/50 ratio typically) is recommended for freeze protection and corrosion inhibition. Specific coolant type (e.g., conventional green or OAT) should be confirmed in the manual.
Grease:
General purpose lithium-based grease (e.g., NLGI #2) is typically specified for various grease points.
Common Wear Items:
Clutch wear, hydraulic seal leaks, PTO spline wear, front axle kingpin wear, exhaust manifold leaks, starter motor reliability.
Electrical Gremlins:
Corroded electrical connections, faulty ignition switches, and aging wiring harnesses are common issues in tractors of this vintage.
Massey Ferguson Legacy:
Massey Ferguson has a long-standing reputation for producing robust and reliable agricultural machinery, dating back to the mid-19th century. Known for innovation and practical design.
Mf50B Era:
