Service Professional’s Advice
Before returning any LGT tractor to service, verify that all safety interlocks (seat switch, PTO switch, neutral switch) are functioning correctly. When servicing the Eaton Model 11 transmission, maintain absolute cleanliness. The precision-fit ball pistons are sensitive to any contamination. Always use SAE 20 detergent motor oil for the hydrostatic system and check levels only when the fluid is cold.
