John Deere (Timberjack) Harvesters

Brake fluid capacity & service interval

John Deere (Timberjack) Harvesters use brake fluid with a capacity of 0.2 liter. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Across the 770, 1070A, 1270B, 1270C, and 1470A harvester models, the hydraulic brake system capacity is uniformly rated at 0.2 liters, a figure consistent with a small, self-contained brake circuit rather than a shared reservoir integrated into a larger hydraulic system.
  • The 0.2-liter figure represents a service fill capacity, meaning the volume required to maintain or refill the system during routine maintenance rather than a full overhaul or dry-fill quantity.
  • All five models carry a normal use condition designation for the brake fluid specification, meaning the listed capacity applies to standard operating environments rather than severe-duty cycles such as extreme temperatures or heavy continuous loading.
  • The consistent 0.2-liter capacity across the 770, 1070A, 1270B, 1270C, and 1470A suggests a shared hydraulic brake circuit architecture across these harvester variants, despite differences in model designation and size class.
  • In hydraulic brake systems of this type, the small reservoir volume reflects a closed-loop design where fluid loss under normal conditions is minimal, making the 0.2-liter capacity sufficient for top-up servicing between full fluid changes.
