The Ford 3600 and Its Agricultural Legacy
The Ford 3600 tractor was introduced in the mid-1970s as part of Ford’s 1000 Series, designed to meet the needs of small farms and utility operations. Built in Basildon, England, and exported globally, the 3600 featured a 3-cylinder diesel or gasoline engine producing around 48 horsepower, a 6-speed or 8-speed manual transmission, and a robust hydraulic system. Ford Motor Company, already a major player in agricultural machinery since the 1939 9N model, sold tens of thousands of 3600 units across North America and Europe. The tractor’s simplicity, reliability, and ease of maintenance made it a favorite among farmers and rural municipalities.
Transmission and Final Drive Fluid Selection
The transmission and rear axle of the Ford 3600 share a common sump, meaning the same fluid lubricates gears, differential, and hydraulic components. While New Holland dealers often recommend proprietary oils, many operators seek cost-effective alternatives.
Recommended options include:
Power Steering Fluid Compatibility
The Ford 3600 uses a separate power steering system, which can accept:
A maintenance technician in Georgia switched from dealer-branded oil to a universal fluid from Rural King and reported no performance issues after 500 hours of use. He noted that the fluid worked well in both transmission and hydraulics, and the cost savings allowed more frequent changes.
In California, a fire tanker pilot who also maintained farm equipment used Castrol Multi-Use oil in his 3600 during the 1980s. Despite the tractor’s age, the system remained leak-free and responsive, proving that quality universal oils can match OEM recommendations.
Preventive Maintenance Recommendations
The Ford 3600 tractor remains a dependable workhorse, and choosing the right fluids is essential for preserving its performance. While dealer oils offer peace of mind, universal tractor fluids that meet OEM specs provide a practical and economical alternative. With proper maintenance and informed choices, the 3600 can continue serving farms and fields for decades to come.

The transmission and rear axle of the Ford 3600 share a common sump, meaning the same fluid lubricates gears, differential, and hydraulic components. While New Holland dealers often recommend proprietary oils, many operators seek cost-effective alternatives.
Recommended options include:
- Universal Tractor Hydraulic Transmission Fluid (UTHF)
Meets Ford M2C 134D or M2C 159A/B specifications. Available from brands like Unimark, Chevron, and Shell.
- SAE 15W-40 STOU (Super Tractor Oil Universal)
Suitable for engine, transmission, and hydraulics in older tractors. Offers good cold-start performance and wear protection.
- Mineral Gear Oil SAE 90
Used in some regions for final drives, though not ideal for shared sump systems due to poor hydraulic compatibility.
Power Steering Fluid Compatibility
The Ford 3600 uses a separate power steering system, which can accept:
- ATF (Automatic Transmission Fluid)
Type F or Dexron III, depending on climate and availability.
- Hydraulic Oil ISO 32 or 46
Offers better viscosity control in warm climates.
- 15W-40 Engine Oil
Used by some operators in Deutz and Ford tractors for all systems, though not ideal in cold weather.

Preventive Maintenance Recommendations
- Change transmission/hydraulic fluid every 600–800 hours or annually
- Inspect fluid color and viscosity during each service
- Replace filters and clean sump screens to prevent contamination
- Use fluids with Ford M2C 159A/B or M2C 134D spec for compatibility
- Avoid mixing brands or types unless specifications match
