What It Is

This starter solenoid is a replacement relay that controls the high-current flow from the battery to the starter motor when you turn the key. It’s designed for Poulan, Husqvarna, Cub Cadet, MTD, and Craftsman lawn tractors, including models like the YS4500 and LT2000.

Fitment & Compatibility

Check these before buying:

• OEM cross-references: Fits original part numbers 532192507, 192507, 582042801, 582042802, 725-06153A, 21546294, and 435-325.
• Brand/model fit: Compatible with most Poulan, Husqvarna, Cub Cadet, MTD, and Craftsman tractors from the 1990s–2010s. Confirm your machine’s OEM part number matches one above.
• Physical dimensions: Approx. 2.5” x 2” x 2”. Verify mounting hole spacing (typically 2.5” center-to-center) and terminal layout (large battery/starter posts + small control spades).
• Voltage: 12V DC only. Not for 6V or 24V systems.
• Deck size irrelevant: This part is engine/electrical system-specific, not deck-dependent.

How to verify: Look at your old solenoid—check the stamped part number, count terminals (usually 4), and measure mounting hole distance. If it matches, this will work.

Key Things to Know

• Quality: This is an aftermarket replacement, not OEM. Most users report it works fine for the price, but a few note slightly thinner terminals or less durable housing than factory parts. For $10, it’s a fair trade-off.
• Installation difficulty: Easy—disconnect battery negative, remove two mounting bolts, unplug spade connectors, swap wires one at a time (label them first). Takes 10–20 minutes.
• Common gotcha: The small control wires (usually red/white) are often fragile and break at the connector. Inspect them before installing—if damaged, replace the connector or splice in new wire.
• Test before full reassembly: Reconnect battery, turn key to start. If you hear a click but no crank, the solenoid is likely good but the starter or battery may be weak.

Should You Buy It

If your tractor clicks but won’t start, and you’ve ruled out a dead battery or bad starter, this solenoid is a cheap, easy fix. It’s right for DIYers on a budget who don’t need OEM durability for heavy commercial use. For occasional mowing, it’ll get you running again.
