139-2357 120-5477 Spindle Assembly Fits for Toro 48" 54" 60" Deck TimeCutter HD Titan ZX ZTR HD Z Master Riding Lawn Mower Replaces 115-9693 117-1250

What It Is

This is a replacement spindle assembly for Toro zero-turn mowers, designed to drive the mower blades on 48", 54", and 60" decks. It’s a direct-fit part for TimeCutter, Titan, HD, ZX, ZTR, and Z Master models.

Fitment & Compatibility

• Deck sizes: 48", 54", 60" – confirm your deck measures one of these.
• Models: Fits Toro TimeCutter, Titan HD, ZX, ZTR, and Z Master series. Check your model number (e.g., 747xx, 748xx, 749xx).
• OEM cross-references: Replaces Toro part numbers 115-9693 and 117-1250. Also listed as 139-2357 and 120-5477.
• Measurements: Verify spindle bolt pattern (typically 3-bolt, 2.5" center-to-center) and shaft diameter (usually 5/8" or 3/4"). Measure your old spindle before ordering.
• What to check: Deck part number (stamped on deck), spindle housing height, and whether you need a complete assembly or just bearings.

Key Things to Know

• Installation difficulty: Moderate. Requires basic tools (wrenches, socket set) and a jack to lift the mower. Expect 30–60 minutes per spindle.
• Common gotcha: The spindle shaft may not include a blade bolt – reuse your old one or buy a new bolt (typically 5/16" or 3/8" grade 8).
• Quality: Aftermarket part, not OEM Toro. One review is 5.0, but limited feedback. Inspect housing and bearings for smooth rotation before installing.
• Deck alignment: Replace all spindles at once if possible to avoid uneven blade height. Measure deck levelness after installation.

Should You Buy It

If you need a cost-effective replacement for a worn or seized spindle on a Toro zero-turn with a 48–60" deck, and you’re comfortable with moderate DIY work, this is a solid bet. For critical commercial use or if you prefer OEM fit, consider the genuine Toro part instead.
