Additional Notes

  • The front differential fluid capacity across all New Holland PowerStar configurations listed — spanning both the T4 series (2012-2018) and the numeric series starting in 2021 — is uniformly 4.5 liters. A capacity at this level is typical of a front axle differential housing in a mid-range agricultural tractor, sized to lubricate the ring and pinion gears as well as the differential carrier assembly without excess volume.
  • The 4.5-liter figure represents a service fill capacity, meaning the amount of fluid required when refilling a drained but otherwise intact differential housing during routine maintenance. Service fill volumes are generally lower than overhaul capacities, which would account for additional fluid retained in passages, bearings, and seals during a full disassembly.
  • All listed configurations share a check interval of every 300 hours under normal use conditions. At this interval, the fluid level is verified without a full drain and refill, allowing early detection of leaks or consumption before the scheduled change interval is reached.
  • The change interval for all listed models under normal use conditions is 1,200 hours or 24 months, whichever comes first. The dual-trigger structure — combining an hour-based threshold with a calendar-based one — accounts for tractors that accumulate operating hours slowly, where fluid degradation from age and moisture absorption can occur independently of mechanical wear cycles.
  • The T4.55, T4.65, and T4.75 PowerStar models (2012-2018) carry identical front differential fluid specifications to the later numeric-designation models introduced from 2021 onward. The 4.5-liter capacity and the 300-hour check / 1,200-hour or 24-month change schedule are consistent across both generations despite the difference in model naming conventions.
  • The 2021 numeric series spans six power variants — the PowerStar 65, 75, 90, 100, 110, and 120 — all sharing the same front differential fluid capacity and service intervals. The uniformity across a range covering notably different power outputs suggests a common front axle assembly is used throughout the lineup.
