What It Is

This is an upgraded aftermarket recoil pull starter assembly designed to replace the OEM starter on Briggs & Stratton engines (models 450E, 500E, 550E, 08P502, 093J02) and compatible Troy-Bilt TB115/TB110 and Craftsman M115/M110 lawn mowers. It provides the pull mechanism to start the engine when the original starter fails or wears out.

Fitment & Compatibility

Before buying, confirm three things:

• Engine model: Must be one of the listed Briggs & Stratton engines (e.g., 08P502, 093J02). Check the engine shroud for a stamped model number—don’t rely on mower brand alone.
• Mower brand/model: Fits Troy-Bilt TB115/TB110 and Craftsman M115/M110, but only with those specific engines. Not universal.
• OEM reference numbers: Replaces OEM 593959, 591139, 590588, 593961. Verify your original part number by removing the old starter and checking the back.
• Physical fit: The starter housing measures roughly 4.5 x 4.5 inches with a 2-inch pulley diameter. Measure your mounting hole spacing (typically 3.5 inches center-to-center) and rope length (stock is ~60 inches) to avoid mismatches.

Key Things to Know

• Quality vs OEM: This is an aftermarket part with upgraded plastic housing and a stronger spring. Some users report it feels sturdier than the original, but it may not last as long as genuine Briggs & Stratton parts under heavy use.
• Installation difficulty: Moderate—requires removing the old starter (usually 2-3 bolts), transferring the rope and handle, and aligning the spring. No special tools needed, but you’ll need to wind the spring correctly (clockwise for most Briggs engines). Watch a video if you’re not mechanically inclined.
• Common gotcha: The rope length is fixed at 60 inches. If your mower’s deck is deeper or the rope guide is positioned differently, you may need to shorten it. Also, the mounting bolts are not included—use the ones from your old starter.
• Returns: Check the seller’s return policy. Some aftermarket starters have a 30-day window; if it doesn’t fit, you’ll need to act fast.

Should You Buy It

If you have a compatible Briggs & Stratton engine (450E/500E/550E series) on a Troy-Bilt or Craftsman push mower and your original starter is slipping, broken, or hard to pull, this $15.99 upgrade is a solid budget fix. It’s not for heavy-duty commercial use, but for home lawn care it offers reliable starting with a slight quality edge over the original. Skip it if you need exact OEM fit or have a different engine model.
