746P06891 Throttle Cable for Cub Cadet ZT1-42 ZT1-46 ZT1-50 ZT1-54 ZT2-60 ZTS1-42 ZTS1-46 ZTS1-50 ZTS2-50 ZTS2-54 ZTS2-60 KH FAB Lawn Mover Engine, 51" Lawn Mower Throttle Control Cable 746-06891

What It Is

The 746P06891 is an OEM replacement throttle control cable for select Cub Cadet ZT series zero-turn mowers and KH FAB lawn tractors. It connects the throttle lever to the engine carburetor, enabling smooth engine speed adjustment. Designed for 51-inch deck models, it restores proper throttle function when the original cable binds, snaps, or loses tension.

Fitment & Compatibility

Verify your mower’s model and deck size before purchasing. This cable fits Cub Cadet ZT1-42, ZT1-46, ZT1-50, ZT1-54, ZT2-60, ZTS1-42, ZTS1-46, ZTS1-50, ZTS2-50, ZTS2-54, ZTS2-60, and KH FAB lawn mowers with 51-inch decks. The OEM part number is 746-06891 (also listed as 746P06891). Measure your original cable’s overall length and end fitting type—this cable is a direct OEM replacement, so it should match exactly. If your mower uses a different cable length or clip style, it won’t work. Check your owner’s manual or existing part number for confirmation.

Key Things to Know

• Quality: OEM-grade construction with a steel inner wire and nylon outer sheath. Resists corrosion and fraying, but not designed for heavy-duty commercial use.
• Installation: Moderate difficulty—requires routing the cable along the frame, attaching to the throttle lever and carburetor bracket. May need to remove the battery or fuel tank for access. Basic hand tools (wrenches, pliers) and a cable cutter are helpful.
• Common Gotchas: The cable can kink if bent too tightly during routing. Ensure the inner wire slides freely before final tightening. If your engine model uses a different carburetor linkage, the cable end might not align—double-check the attachment point.
• Adjustment: After installation, adjust the cable barrel nut to achieve full throttle range (idle to wide-open). Over-tightening can cause the throttle to stick.

Should You Buy It

If your Cub Cadet ZT series mower’s throttle is stiff, unresponsive, or the original cable is broken, this is the correct OEM fix. It’s a reliable, direct-fit replacement for DIY maintenance, but verify your model’s deck size and existing cable part number to avoid returns. For non-compatible mowers, look for a universal cable kit instead.
