Figure 71. Winglet 4. Eccentric2. Hinge pin 5. Upper hole3. Stop bolt• Rotate the rear (closest to traction unit) eccentricuntil the outside blade tip is about 1/8 inch higherthan the desired height of cut (Figure 7).Note: There is a notch on the eccentric hex which is180° from the lobe on the eccentric cam (Figure 8).Use the notches to reference the location of thelobes when adjusting the eccentrics.Figure 81. Eccentric notch• Tighten the bolt and nut for this eccentric to 110ft-lb (149 N-m).• Adjust the forward eccentric until it just makescontact with the inner slot surface of the wingletpivot brackets.• Tighten the bolt and nut for this eccentric to 110ft-lb (149 N-m).• Repeat the procedure on the opposite winglet. Referto Adjusting the Cutting Unit Pitch procedure inMower Maintenance.5Checking Tire PressureNo Parts RequiredProcedureCheck the air pressure in all the tires before operatingthe machine. The correct air pressure in the front tiresis 50 psi (345 kPa) and the rear tires is 30 psi (207 kPa)(Figure 9).Important: Maintain pressure in all tires toensure a good quality-of-cut and proper machineperformance.Do not under-inflate.Figure 96Checking Fluid LevelsNo Parts RequiredProcedure1. Check the engine oil level before starting the engine,refer to Checking the Engine Oil Level in EngineMaintenance.18
