This Caltric replacement starter is a direct-fit 15-tooth steel-gear unit engineered to replace John Deere MIA13038 / Briggs & Stratton 592599 starters on many lawn and compact tractor models.

When your mower or small tractor won't turn over, a reliable starter is the first thing to check. This Caltric starter is designed to match mounting, gear count, and electrical connections used on a wide range of John Deere residential and commercial models and numerous Briggs & Stratton engine part numbers. It is sold as a single unit and intended to be swapped in where the original starter matches the pictured design and specifications.

Which machines will this starter work with?

This starter fits many John Deere models across the 100 and some Ztrak and D-series lines, plus several Briggs & Stratton engine variants. Always compare the physical appearance and mounting pattern of your existing starter to the picture before purchasing to confirm fitment.

• Common John Deere models: E120, E130, E140, E150, E160, E170, E180 and many X- and Z-series tractors and mowers.
• Also compatible with D-series and L-series residential tractors listed in product details.
• Matches multiple Briggs & Stratton OEM numbers (examples include 40N777 and 40N877 series).
• OEM references: John Deere MIA13038 and Briggs & Stratton 592599 for cross-checking.

How is the starter built and what key specs matter?

The unit uses a 15-tooth steel drive gear and a robust motor housing intended for outdoor power equipment starting duty. Key factors to verify on your existing unit are tooth count, mounting bolt locations, and electrical terminal arrangement to ensure interchangeability.

• Drive gear: 15 teeth, steel construction for durability.
• Electrical connections: standard terminal layout matching listed OEMs.
• Mounting: bolt pattern designed to align with compatible John Deere housings.
• Sold as: one starter per order for direct replacement.

What should I check before installing this replacement?

Before removing the old starter, confirm battery condition, cable integrity, and that the starter is the root cause of starting failure. During replacement, transfer any heat shields or brackets and torque mounting bolts to the manufacturer’s specifications for a secure fit.

• Compare the pictured unit to your installed starter for visual match.
• Check battery voltage and cable ends to avoid reinstallation of a faulty starter.
• Follow safe shutdown and battery-disconnect procedures before work.
• Keep fasteners and return any retained shims or spacers in the same orientation.

Who is this for: This Caltric starter is intended for owners and technicians maintaining residential tractors, lawn tractors, and Ztrak mowers that use John Deere MIA13038 or equivalent Briggs & Stratton starters.

If you maintain multiple machines or routinely repair outdoor power equipment, this starter provides a straightforward swap—provided you verify the fit against the included photo and listed part references before installation.
