Ponsse Harvesters

Transfer case fluid capacity & service interval

Ponsse Harvesters use transfer case fluid with a capacity range of 3,5 to 6 liters. The service interval for fluid changes is 1200 hours. The data covers 8 configurations.

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

Additional Notes

  • The Ponsse Beaver transferbox holds 3.5 liters across both the pre-2001 and 2001-onward configurations, with a fluid change interval of 1,200 operating hours under normal use conditions.
  • The Ponsse Buffalo Dual carries a larger transferbox capacity of 4.8 liters, also paired with a 1,200-hour change interval under normal use, reflecting the greater fluid volume typical of dual-configuration driveline housings.
  • The Ponsse Ergo transferbox holds 4 liters with a 1,200-hour change interval under normal use, a figure consistent across both the pre-2001 and 2001-onward variants.
  • A separate capacity figure of 6 liters is specified for the Ergo transferbox-with-pump configuration. No change interval is listed for this combined assembly, distinguishing it from the standalone transferbox entry which carries the 1,200-hour interval.
  • The 6-liter figure for the Ergo transferbox-and-pump assembly represents a total system fill that accounts for the additional fluid volume held within the integrated pump, rather than the transferbox housing alone.
  • The 1,200-hour change interval, applied across the Beaver, Buffalo Dual, and Ergo transferbox entries, is tied specifically to normal use conditions. Operating hours are the standard service measurement in forestry machinery, where annual mileage is not a meaningful metric.
  • Capacity values remain identical between the pre-2001 and 2001-onward rows for all three models, indicating no change in transferbox fluid volume across the 2001 model year boundary in the specifications.
