Additional Notes

  • The front differential on the Jacobsen Ride-on green and fairway mowers R-311 (EC) Tier IIIb (69167), R-311 Tier IIIb (69166), and R-311T Tier IIIb (69171) each holds 1.95 liters, a figure that reflects a service fill capacity for the front differential assembly.
  • All three configurations share an 8-hour check interval for the front differential fluid, meaning fluid level verification is scheduled at a high frequency relative to typical operational use.
  • The fluid change interval across the R-311 (EC), R-311, and R-311T Tier IIIb configurations is set at 12 months under normal use conditions, placing the service cycle on an annual calendar basis rather than an hour-meter basis.
