Additional Notes

  • The Ford 20 1120 and 1220 share a hydrostatic transmission fluid capacity of 16 liters, while the 1320 and 1520 require 22 liters, reflecting the larger hydraulic circuit demands of the higher model variants.
  • A 6-liter difference separates the two capacity groups across the 1988-1996 range, with the 1320 and 1520 holding roughly 37 percent more fluid than the 1120 and 1220.
  • All four models specify a fluid level check interval of 50 operating hours under normal use conditions, a relatively short interval consistent with hydrostatic systems where fluid condition and level are critical to pump and motor longevity.
  • The fluid change interval is set at 300 operating hours across all four models, meaning a full drain and refill is due after approximately six check cycles at the 50-hour mark.
  • Hour-based service intervals are standard for agricultural and compact utility equipment, where annual mileage is not a meaningful measure of mechanical wear or fluid degradation.
  • The 16-liter capacity on the Ford 20 1120 and 1220 covers the combined hydrostatic transmission and associated hydraulic circuit, as hydrostatic systems typically integrate the transmission and hydraulic functions into a shared fluid reservoir.
  • All specifications across the 1120, 1220, 1320, and 1520 are rated for normal use conditions, with no separate severe-duty interval listed for any of the four models.
