Fuel System:

Direct Injection Diesel with likely a Bosch or Simms fuel injection pump system. Includes fuel filters, fuel lines, and injectors.

🔧 Transmission

Transmission Type:

Manual Gearbox with likely multiple forward and reverse gears. May feature a multi-speed PTO (Power Take-Off).

Gear Ratios:

Detailed gear ratios for each forward and reverse speed will be in the manual, crucial for understanding torque multiplication and operational speeds.

Transmission Features:

Likely includes a differential lock for enhanced traction, independent PTO, and a sturdy clutch system.

Optional Transmission Features:

While not explicitly stated, some tractors of this era might have offered variations like a creeper gear or different PTO speed options depending on the market or specific utility packages.

📐 Dimensions

Overall Length:

Approximate (Specific dimensions require detailed specification data, typically 3-4 meters)
