591139 Recoil Starter Compatible with 593959 590588 593961 450E 500E 550E 575E Troy Bilt Craftsman TB110 TB200 140CC 150CC Engine Lawn Mower Recoil Pull Start Assembly

What It Is

This is a replacement recoil starter assembly (pull-start mechanism) for small engines in Troy-Bilt, Craftsman, and similar lawn mowers. It’s designed to restore starting function when the original starter rope snaps, the spring breaks, or the pulley jams.

Fitment & Compatibility

Before buying, confirm your engine’s model number (e.g., 140cc, 150cc) and your mower model (e.g., TB110, TB200, 450E, 500E, 550E, 575E). This part is an aftermarket replacement for OEM numbers 591139, 593959, 590588, and 593961. Measure the bolt hole spacing (typically 3.5 inches center-to-center) and the overall housing diameter (approx. 4.5 inches) to match your current unit. It fits many single-cylinder Briggs & Stratton and MTD engines, but not all—check your engine’s starter mounting pattern.

Key Things to Know

• Quality: Aftermarket but solid; most users report it works as well as OEM for a fraction of the cost. Plastic housing may be slightly less durable than original, but acceptable for home use.
• Installation: Easy—remove two bolts, swap the old unit, and reconnect the rope and spring. No special tools needed, but watch for sharp edges on the spring.
• Common gotchas: Ensure the rope is wound in the correct direction (counterclockwise for most engines). Also, verify that the starter cup on the engine engages smoothly with the new unit’s pawls.
• Fitment nuance: Some mowers with a different deck size (e.g., 21-inch vs 22-inch) still use the same engine, so focus on the engine model, not the deck.

Should You Buy It

If your Troy-Bilt or Craftsman mower (with a 140cc or 150cc engine) won’t start because the recoil is broken, this is a budget-friendly, reliable fix. It’s best for DIY homeowners who want a quick replacement without paying OEM prices. Avoid if you need a heavy-duty unit for commercial use or have an unusual engine mount.
