Hürlimann XN

Power steering fluid capacity & service interval

Hürlimann XN uses power steering fluid with a capacity of 41 liters. Service intervals include checking every 150 hours and changing every 1200 hours. The data covers 4 configurations.

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

Additional Notes

  • The Hürlimann XN series integrates the transaxle, hydraulic system, and power steering into a single shared fluid circuit, which accounts for the notably large 41-liter capacity across all four variants covered here.
  • A 41-liter fill volume is substantially higher than what is typical for passenger vehicle power steering systems, reflecting the demands of agricultural tractor hydraulics where steering, implement control, and transmission lubrication draw from a common reservoir.
  • The XN 706, XN 707, XN 708, and XN 709 all share an identical 41-liter capacity, with no variation across the model range for the 1998-2005 production span.
  • Under normal use conditions, a fluid level check is specified at every 150 operating hours, an interval calibrated to engine hours rather than calendar time or distance, as is standard practice for agricultural equipment.
  • The fluid change interval under normal use conditions is set at 1200 operating hours, meaning a single fill could remain in service for a considerable period before a full drain and refill is required.
  • The ratio between the check interval and the change interval is 8:1, meaning eight level checks are expected to occur for every one complete fluid change within a normal service cycle.
