Engine Family:
David Brown diesel engines (e.g., AD4.203, AD6.354 for later models, earlier models may use different designations).
Displacement Range:
Approximately 3.3 to 5.5 liters (varies significantly by model).
Cylinders:
Typically 3 or 4 cylinders (e.g., 885/995 often 3-cylinder, 1210/1410 often 4-cylinder).
Horsepower Range:
Approximately 50-90 PTO horsepower, dependent on specific model and engine.

Fuel Filter Replacement:
Periodically, often alongside oil changes or as recommended by usage.
Engine Oil Type:
API CD or CE rated diesel engine oil, viscosity typically SAE 15W-30 or 10W-30 depending on ambient temperature (refer to manual for exact specs).
Transmission Hydraulic Fluid:
Often a universal tractor transmission fluid (UTTO) or equivalent hydraulic fluid (e.g., Type 'H' or equivalent is common for older tractors).
Coolant Type:
Ethylene glycol based antifreeze/coolant mixture, typically a 50/50 blend with distilled water.
Engine Wear:
General wear and tear on older engines, potential for oil leaks, piston ring wear, and injector issues.
