Troy-Bilt Model 554 User Manual

Disconnect the spark plug wire and 

ground against the engine before performing any 

adjustment, repairs or maintenance.

Refer to the Engine Operator’s Manual packed with your 

edger for a detailed description of all engine-related service 

specifications.

The edger blade is sharp. Wear leather 

work gloves to protect your hands when working 

around the edger blade.

Use two wrenches (one wrench to prevent the hex bolt 

head from spinning and the other to remove the flange 

nut) to remove the edger blade. Refer to Fig. 6–1.

Remove and discard the edger blade but retain the flange 

nut.
Install the replacement edger blade and the flange nut 

removed earlier. Use a torque wrench to tighten the flange 

nut to between 37 foot-lbs. and 50 foot-lbs.
NOTE: Make certain that the drive belt is seated correctly 

on the blade spindle and that it is riding smoothly on the 

spindle sheaves and is not pinched between them. Repeat 

the first three steps if the belt is pinched.
