BlueStars 725-12066 Ignition Switch 3 Position 6 Pin with Keys - Compatible with Cub Cadet Cadet ZT1-42 ZT1-46 ZT1-50 ZT1-54 ZT2-50 ZT2-54 MTD Z510 Z530 Z550 Z560 Z5200 - Replaces 725P12066 925-12066

What It Is

The BlueStars 725-12066 is a 3-position (Off/Run/Start) ignition switch with 6 pins and two keys, designed to replace faulty switches on Cub Cadet zero-turn mowers and select MTD lawn tractors. It controls power to the starter, ignition, and safety circuits.

Fitment & Compatibility

This switch fits Cub Cadet ZT1 and ZT2 series models (e.g., ZT1-42, ZT1-46, ZT1-50, ZT1-54, ZT2-50, ZT2-54) and MTD Z-series mowers (Z510, Z530, Z550, Z560, Z5200). It replaces OEM part numbers 725P12066 and 925-12066. Before buying, confirm your mower’s model number (found on a sticker under the seat or on the frame). Measure the switch’s mounting hole diameter—it should be 1.18 inches (30 mm). Verify the wiring harness connector matches a 6-pin flat blade configuration. This is an aftermarket part, not OEM Cub Cadet, but it matches the original dimensions and pin layout.

Key Things to Know

• Quality: Rated 4.5 stars from 829 reviews. Most users report it works as a direct replacement, though a few note the key feels less sturdy than OEM.
• Installation: Easy for DIYers—disconnect the battery, unplug the old switch, remove the retaining nut, and install the new one. No wiring splicing needed if the connector matches.
• Common gotcha: The included keys may not match your existing ignition key. You’ll use the new keys with this switch only.
• Durability: Plastic housing is standard for this price point. If you mow in wet conditions, consider sealing the connector with dielectric grease to prevent corrosion.

Should You Buy It

If your Cub Cadet or MTD Z-series mower’s ignition switch is failing (intermittent start, no crank, or loose key feel), this is a reliable, low-cost fix. It’s ideal for DIY homeowners who want a quick replacement without paying OEM prices ($30+). Not for commercial use or if you need the exact OEM feel—stick with the genuine Cub Cadet part for that.
