Troy-Bilt TB575SS: Two-Cycle Straight-Shaft String Trimmer Service
The Troy-Bilt TB575SS uses a two-stroke engine requiring a premixed fuel and oil ratio as specified in the owner’s manual.

The string trimmer repair help section covers TB575SS carburetor service, fuel filter replacement, and trimmer head line winding.
Most Replaced Parts on the Troy-Bilt TB575SS
Carburetor for the Troy-Bilt TB575SS

Replace the air filter at the start of each trimming season. A clogged filter causes the engine to run rich and lose cutting power.

Annual spark plug replacement maintains reliable starting. Always use the fuel mixture ratio specified in the TB575SS owner’s manual.
Trimmer Head for the TB575SS
The bump-feed trimmer head advances line when tapped against the ground. Replace the head when the bump knob mechanism no longer advances line reliably.

Why does my Troy-Bilt TB575SS not start after off-season storage?

How does the Troy-Bilt TB575SS differ from the TB252S?
The TB575SS is a higher-displacement straight-shaft model while the TB252S is a curved-shaft model in the Troy-Bilt trimmer lineup. Both use two-stroke engines and share many carburetor and air filter service requirements, but trimmer head and shaft components differ between the two configurations.

Replace the spark plug annually or every 50 hours of use. A plug with black carbon deposits indicates a rich fuel mixture from a clogged air filter or improperly mixed fuel.
