LSTractor U series

Power steering fluid capacity & service interval

LSTractor U series uses power steering fluid with a capacity of 47 liters. Service intervals include checking at 50 hours and changing at 600 hours. The data covers 3 configurations.

Additional Notes

  • The LSTractor U series power steering fluid is shared within a combined transaxle, hydraulic system, and power steering circuit, which accounts for the relatively large 47-liter capacity across all three models.
  • The U5010, U5020, and U5030 each carry an identical 47-liter fluid capacity for the combined transaxle, hydraulic system, and power steering circuit.
  • A check interval of every 50 hours applies to all three models under normal use conditions, reflecting a routine monitoring schedule rather than a full fluid exchange.
  • The change interval is set at 600 hours for normal use across the U5010, U5020, and U5030, representing the full drain-and-refill cycle for the shared circuit.
  • The gap between the 50-hour check interval and the 600-hour change interval indicates that fluid level and condition monitoring occurs twelve times before a full fluid change is due under normal use.
