Manufacturer:
David Brown (or potentially Perkins, common for tractors of this era, specific to 1212 needs confirmation)
Engine Family:
Likely a four-cylinder diesel engine, typical for this class of tractor. Specific displacement and model number would be detailed in the manual.
Horsepower Estimate:
Estimated 60-70 HP range, common for tractors in this power class.
Torque Estimate:
Torque figures would be crucial for heavy draft work and are detailed in the manual.
Injection System:
Likely a direct injection system with an inline or rotary fuel injection pump. Manual will specify model and service procedures.
Daily Checks:
Fluid levels (engine oil, coolant, hydraulic oil), tire pressures, visual inspection for leaks, PTO shaft condition, hitch linkage check.
Hourly Checks:
Greasing points, air filter inspection/cleaning, fuel filter check, hydraulic oil filter replacement (based on operating hours).
Engine Oil:
Specific API service classification and viscosity grade (e.g., SAE 30, 15W-40) would be provided. Common for this era: HD/CD or higher.
Hydraulic Fluid:
Type of hydraulic oil (e.g., Universal Tractor Transmission Fluid - UTF, or specific hydraulic oil), viscosity, and capacity. Compatibility with shared transmission/hydraulic reservoirs is key.
Coolant:
Ethylene glycol based coolant, specific antifreeze-to-water ratio, and potential for heavy-duty coolant additives.
Common Problems:
Typical issues for tractors of this age might include wear in the transmission synchronizers (if applicable), hydraulic system leaks or reduced pressure, electrical harness degradation, and starter motor issues. The manual would offer solutions.
Preventative Maintenance:
Regular lubrication, fluid changes, and timely filter replacements are crucial to prevent common wear-related failures.
