Engine Family:
Ford New Holland 4-cylinder diesel engines (specific models vary by tractor model, e.g., Ford 4.2L Diesel).
Horsepower Range:
Typically ranges from 40-70 PTO horsepower, depending on the specific tractor model.
Torque Specifications:
Specific torque values for engine components (e.g., head bolts, crankshaft bearings) will be detailed in the manual.
Injection Type:
Indirect injection (IDI) or direct injection (DI) diesel fuel systems, depending on the engine variant. Likely Bosch or similar injection pumps.
Cooling Medium:
Water-glycol mixture (antifreeze).
Oil Type:
The manual will specify the recommended engine oil viscosity and API service classification (e.g., API CD or CE for this era).
Transmission Type Common:
Likely 8-speed or 16-speed manual transmissions (e.g., 4 forward + 4 reverse gears with a hi/lo splitter). Some models may offer 8-speed partial power shift (16F/8R).
Optional Transmission:
Possibility of creeper gears or other specialized transmissions depending on the specific tractor configuration.
Clutch Type:
Dual-clutch system for tractor PTO engagement and transmission engagement.
Pto Speed:
Standard 540 RPM PTO, possibly with a 1000 RPM option on some models.
Transmission Fluid:
The manual will specify the required transmission and hydraulic fluid type (likely a UTF - Universal Tractor Transmission fluid) and capacity.
Wheelbase:
Varies by model, typically around 80-85 inches.
Length:
Varies by model, generally around 120-140 inches.
Width:
Varies by model and tire configuration, typically 60-70 inches.
Operating Weight:
Varies by model, generally in the range of 3,500 - 5,500 lbs (1588 - 2495 kg) without ballast.
Drawbar Horsepower:
Drawbar horsepower will be lower than PTO horsepower, specified in the manual for performance calculations.
Rollover Protection:
ROPS (Rollover Protective Structure) may be standard or optional depending on the specific tractor configuration and date of manufacture. The manual will detail installation and maintenance of ROPS if applicable.
Braking System:
Mechanical or hydraulic-actuated brakes, potentially with independent brake operation for maneuverability.
Seatbelt:
Seatbelts are likely present if ROPS is fitted. The manual will cover their inspection.
Operator Presence Control:
Typical safety interlocks will be detailed, such as PTO disengagement if the operator leaves the seat.
Dashboard Instruments:
Basic analog gauges for oil pressure, coolant temperature, fuel level, tachometer, and ammeter/voltmeter. Hour meter is essential.
Power Steering:
Many models featured power steering as standard or optional, significantly reducing operator fatigue.
Electrical System Voltage:
12-volt negative ground electrical system.
Engine Oil And Filter:
Typically every 200-250 operating hours, or annually, whichever comes first. Manual will specify exact interval and filter part number.
Transmission Hydraulic Fluid:
Recommended change intervals will be provided, often every 500-1000 operating hours.
Air Filter:
Regular inspection and cleaning/replacement based on operating conditions, usually more frequent in dusty environments.
Engine Oil Spec:
Refer to the manual for specific SAE viscosity grade (e.g., 15W-40) and API service classification (e.g., CD, CE).
Hydraulic Fluid Spec:
Universal Tractor Transmission (UTF) fluid is commonly specified, meeting Ford M2C134-D or similar specifications. The manual will confirm the exact specification and capacity.
Coolant Spec:
A 50/50 mix of permanent antifreeze and clean water. Manual will specify suitable antifreeze types.
Common Wear Items:
Hydraulic pump wear, clutch wear, front axle pivot wear, and electrical connection corrosion are common on older tractors.
Engine Common Problems:
Potential issues include injector pump timing, glow plug reliability (on some cold-start variants), and seal leaks.
Ford Tractor Division:
Ford was a dominant force in the tractor industry for decades, known for robust and reliable machines. New Holland acquired Ford's tractor division in 1991, continuing the legacy.
Series Development:
These models represent a transitional period for Ford tractors, with many features evolving from earlier designs and anticipating future New Holland advancements. They were popular utility tractors for various farm tasks.
Manufacturing Locations:
Ford tractors of this era were primarily manufactured in the United States (e.g., Highland Park, Michigan; Troy, Michigan; Basildon, UK for some models).
