Yoursme Complete Spindle Assembly Replacement for Bush Hog 50051388 Spindle Assemble Fits for RDTH FTH ATH EFM TD-1500 and TD-1700 Models Finish Mowers with All Hardware and 50074053 Pulley Sheave

What It Is

This is a complete spindle assembly replacement for Bush Hog finish mowers, including the spindle housing, bearings, shaft, and a 50074053 pulley sheave. It’s designed to drive the mower blades on models like the RDTH, FTH, ATH, EFM, TD-1500, and TD-1700.

Fitment & Compatibility

Before buying, confirm your mower model and deck size (typically 60”–72” for these series). This assembly replaces OEM Bush Hog part 50051388 and includes the pulley (50074053). Check your existing spindle’s bolt pattern (usually 3-bolt) and shaft diameter (commonly 1” or 1-1/8”). Measure your old spindle’s overall height and pulley groove width—this aftermarket unit may differ slightly from OEM. Verify that your deck uses a standard tapered shaft and keyway, not a splined shaft.

Key Things to Know

• Quality: User reviews note decent build quality for the price, but some report bearing noise after a few months—inspect and grease regularly.
• Installation: Moderate difficulty; you’ll need basic tools (wrenches, socket set, torque wrench). The pulley is pre-installed, but you must transfer any spacer or dust cap from your old spindle.
• Gotcha: The included hardware (bolts, lock washers) may not match your deck’s thread pitch—check before disassembly. Also, the pulley sheave diameter might be slightly off, affecting belt tension.
• Warranty: Yoursme offers a 1-year warranty, but read the return policy carefully; some buyers report slow response.

Should You Buy It

If you have a compatible Bush Hog finish mower and need a budget-friendly spindle replacement with all necessary parts included, this is a solid option for DIY repairs. However, if you’re a commercial user expecting long-term durability or need exact OEM specs, consider spending more on a genuine Bush Hog assembly.
