JEENDA Blade Clutch PTO Switch Compatible with Troy-Bilt TB2454 TB2350 Super Bronco 50XP 54XP Mustang Z42 Z46 XP 46 54 42 50 60 XP

What It Is

This is an aftermarket blade clutch PTO switch for Troy-Bilt lawn tractors and zero-turn mowers. It engages and disengages the mower deck’s electric clutch, allowing you to start/stop the blades from the seat. Designed for models like the TB2454, TB2350, Super Bronco 50XP/54XP, and Mustang Z42/Z46/XP series.

Fitment & Compatibility

Before buying, verify your machine’s exact model number (on a plate under the seat or on the frame). This switch fits Troy-Bilt tractors with 42", 46", 50", 54", and 60" XP decks, plus Super Bronco and Mustang Z-series. It replaces OEM part numbers 925-03687, 925-03687A, 925-03687B, and 725-03687. Measure your original switch’s terminal spacing (blade width and pin pattern) to confirm—this has 3 spade terminals. Not compatible with older or non-Troy-Bilt models without cross-checking OEM numbers.

Key Things to Know

• Quality: Aftermarket, not OEM. Most users report it works fine, but a few note slightly looser fit on the mounting bracket. Check for corrosion resistance on terminals.
• Installation: Easy—unplug the old switch, remove two screws, and replace. No special tools needed. Disconnect the battery first.
• Common Gotcha: If your blades don’t engage after swap, the switch might be faulty (rare) or your clutch coil is bad. Test the old switch with a multimeter before buying.
• Wiring: Match wire colors exactly (usually red/black/white). If your harness uses different colors, take a photo before disconnecting.

Should You Buy It

Buy this if your Troy-Bilt’s PTO switch is physically broken (cracked, stuck, or won’t click) and you want a cheap, functional replacement. It’s a solid budget option for DIY repairs on common 2010s–2020s Troy-Bilt models. Skip it if you need OEM durability for heavy commercial use or have a rare older model—cross-reference your OEM part number first.
