What It Is

This is a 3-pack of replacement spindle assemblies for 42-inch and 50-inch Exmark and Toro TimeCutter mower decks. The spindle is the rotating shaft that drives the blade—if it’s wobbly, noisy, or seized, this is the part you need.

Fitment & Compatibility

• Deck size: Fits 42-inch and 50-inch stamped steel decks on Toro TimeCutter models (4200, 4216, 4235, 4260, 5000, 5060, SS5000, SS4225, SS4200, SS4235) and compatible Exmark decks.
• OEM cross-reference: Replaces Toro/Exmark part numbers 117-7268, 117-7267, 117-0751, 117-7439, 121-0751, 139-3214, 285-923. Verify your existing spindle’s part number or look for a stamped number on the housing.
• Measurement check: Measure the mounting hole pattern (center-to-center) on your deck—should be 3.25 inches. Measure the spindle shaft diameter (should be 5/8 inch). If your deck uses a different pattern or shaft size, this won’t fit.
• Brand note: This is an aftermarket part, not genuine Toro. It’s designed as a direct swap, but always compare the housing shape and bearing housing height to your old spindle.

Key Things to Know

• Quality vs. OEM: Aftermarket spindles can vary. This kit has decent reviews (4.6 stars), but expect slightly shorter bearing life than genuine Toro—fine for homeowner use, less ideal for commercial mowing.
• Installation difficulty: Moderate. You’ll need a wrench set, a jack or ramps to lift the mower, and a puller if the old spindle is seized. Plan 30–60 minutes per spindle.
• Common gotcha: The bolts holding the spindle to the deck are often rusted or stripped. Have replacement bolts (grade 8, 5/16-18 x 1 inch) and anti-seize compound on hand.
• Bearing check: Spin the new spindle by hand before installing—it should rotate smoothly with no grinding or wobble. Return immediately if it doesn’t.

Should You Buy It

Buy this if you have a 42- or 50-inch TimeCutter or compatible Exmark deck, need to replace all three spindles at once (common on older decks), and want to save money over OEM parts. Skip it if you mow commercially or need maximum durability—genuine Toro spindles will last longer under heavy use.
