593959 591139 Recoil Starter for Troy Bilt TB110 TB200 140CC 150CC Lawn Mower Brigs Straton 450E 550EX 08P502 093J02 09P602 09P702 Engines 593959 Pull Start Assembly

What It Is

This is a replacement recoil starter assembly for Troy-Bilt TB110/TB200 walk-behind mowers and engines like the Briggs & Stratton 450E, 550EX, and models 08P502, 093J02, 09P602, and 09P702. It pulls the rope to spin the engine flywheel for starting.

Fitment & Compatibility

Before buying, confirm your engine model number (stamped on the valve cover or blower housing) matches one of these: 08P502, 093J02, 09P602, 09P702, 140CC, 150CC, 450E, or 550EX. The part replaces OEM numbers 593959 and 591139. Measure the bolt-hole spacing on your old starter—this unit uses a 3-bolt pattern with 3-inch (76mm) center-to-center spacing. Also check the rope length (should be ~60 inches) and rope diameter (3/16 inch). It will not fit engines with a 4-bolt pattern or different hole spacing.

Key Things to Know

• Quality: This is an aftermarket part, not OEM Briggs & Stratton. It’s functional but may feel slightly less durable than the original. Check for rough edges on the plastic housing before installation.
• Installation difficulty: Easy—requires only a screwdriver and possibly a socket wrench. Remove the old starter (3 bolts), disconnect the rope, and install the new one. No engine disassembly needed.
• Common gotchas: The rope may be pre-wound too tight or too loose out of the box—you can adjust tension by pulling the rope out fully and letting it retract slowly. Also, the included bolts may be a slightly different length than your originals; reuse your old bolts if needed.
• Warranty: Typically 30 days from the seller. No official warranty from Briggs & Stratton.

Should You Buy It

If you need a quick, low-cost fix for a Troy-Bilt TB110/TB200 with a Briggs 450E/550EX engine and your old starter rope snapped or the pulley cracked, this is a solid budget option. It’s not as rugged as OEM, but for occasional home use on a standard push mower, it’ll get you mowing again without breaking the bank.
