Assistance Features:
Limited to operator controls. No electronic driver assistance features.
Connectivity Options:
None. Primarily mechanical and hydraulic systems.
Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions and oil type. Refer to manual for exact specifications.
Engine Oil:
API CD or CE rated diesel engine oil, SAE 15W-30 or 10W-30, depending on climate. Specific David Brown specifications should be consulted.
Hydraulic Fluid:
David Brown Type 3 Fluid (or equivalent universal tractor transmission fluid - UTF) is often specified for the transmission, hydraulic system, and final drives. Capacity varies but is typically around 10-12 gallons.
Transmission Fluid:
Refer to David Brown Type 3 Fluid / UTF specifications. Capacity varies by model and transmission type. It's critical to use the correct fluid to prevent damage to the wet clutch and hydraulic components.
Coolant:
Ethylene glycol antifreeze mixture with a 50/50 ratio of antifreeze to water for freeze protection and corrosion inhibition. Capacity is typically around 5-7 gallons.
Common Problems:
Potential issues include wear in the Selectamatic hydraulic control system, clutch wear, PTO engagement problems, and potential leaks from seals and hydraulic lines. Fuel injection system maintenance is also crucial.
Grease Points:
Numerous grease points on steering components, kingpins, drawbar pivot, PTO shaft, and wheel hubs. Regular greasing is essential for longevity.
Heritage:
David Brown was a well-respected British tractor manufacturer known for innovation and quality, with a history dating back to the early 20th century. The company was eventually absorbed into Tenneco (Case IH).
Evolution:
The 885, 995, 1210, 1212, 1410, and 1412 models represent key developments in David Brown's tractor lineup from the mid-1960s through the 1970s, evolving from earlier designs to incorporate more advanced features.
Production Period:
