Antonio Carraro Supertrac HTM series (35)

Manual transmission fluid capacity & service interval

Antonio Carraro Supertrac HTM series (35) manual transmission fluid capacity ranges from 19,5 to 24,5 liters. Service intervals consist of a 50 hour check and a 400 hour change. The data covers 8 configurations.

Additional Notes

  • The Antonio Carraro Supertrac HTM series splits the manual transmission into two separate housings — front and rear — each with its own fluid capacity and service schedule.
  • The front transmission on the HTM 5400, HTM 5600, HTM 7700, and HTM 8400 holds 19.5 liters, a volume consistent with a dedicated gearbox housing rather than a combined drivetrain sump.
  • The rear transmission across all four variants — HTM 5400, HTM 5600, HTM 7700, and HTM 8400 — carries a notably larger 24.5-liter capacity, reflecting a more substantial housing that likely integrates differential or axle functions alongside the transmission gearing.
  • The combined front and rear fluid volume per tractor totals 44 liters, which is a significant service quantity and has practical implications for fluid procurement and disposal at each change interval.
  • All eight rows share an identical check interval of 50 operating hours, meaning fluid levels in both the front and rear housings are verified at the same frequency regardless of variant.
  • The fluid change interval is set at 400 operating hours across all variants and both transmission positions, applying under normal use conditions.
  • In hour-based service schedules typical of agricultural machinery, a 400-hour change interval means the fluid is renewed roughly once per season for equipment used at moderate annual intensity, while heavier use would reach that threshold sooner.
  • The specifications apply uniformly across the HTM 5400, HTM 5600, HTM 7700, and HTM 8400, with no variation in capacity or service intervals among the four models despite their differing model designations.
