946-05106B Control Cable Compatible with Cub Cadet MTD Craftsman SC300 SC500 SC500Z SC500EZ Throttle Cable Replace 746-05106A, 746-05106B, 746-05106

What It Is

This 946-05106B control cable is the throttle cable for Cub Cadet, MTD, and Craftsman walk-behind self-propelled mowers, specifically the SC300, SC500, SC500Z, and SC500EZ models. It connects the throttle control lever to the engine carburetor, allowing you to adjust engine speed.

Fitment & Compatibility

Before buying, confirm your mower’s model number (not just the name) against the SC300, SC500, SC500Z, or SC500EZ series. This cable replaces OEM part numbers 746-05106A, 746-05106B, and 746-05106. Measure the cable length (housing and inner wire) on your existing cable—this aftermarket version matches the OEM dimensions. It does not fit models with different deck sizes or engine brands (e.g., Briggs & Stratton vs. Kohler) unless the cable routing and attachment points are identical. Check that your mower uses a typical push-pull throttle configuration, not a choke-only or remote cable.

Key Things to Know

• Quality: Aftermarket replacement, not OEM. Users report it works well, but the outer housing may be slightly less flexible than the original, making routing a bit tighter.
• Installation difficulty: Moderate. You’ll need to remove the old cable from the throttle lever and carburetor bracket, then route the new one through the handlebar and deck. Allow 30–45 minutes.
• Common gotcha: The cable end fittings (e.g., barrel or eyelet) must match your throttle lever and carburetor arm. This cable uses standard barrel ends—verify yours are the same before cutting off the old one.
• Lubrication: Apply a light machine oil to the inner wire after installation to reduce friction and extend cable life.

Should You Buy It

If you own an SC300, SC500, SC500Z, or SC500EZ and need a budget-friendly throttle cable that matches OEM dimensions, this is a solid pick. It’s not the original part, but the 4.9-star rating and low price make it a reliable choice for DIY repairs. Avoid it if you need a cable for a different model or prefer exact OEM fitment.
