QCG 946-05145 Throttle/Choke Replacement Cable Compatible with CUB Cadet RZT-L42, RZT-L46, RZT-L50, RZT-L54, RZT-S42, RZT-S46, RZT-S50, RZT-S54 Replace 746-05145 57" Lawn Mower Throttle Cable

What It Is

This is a 57-inch throttle and choke control cable assembly designed to replace the OEM part 746-05145 on select Cub Cadet RZT series zero-turn mowers. It controls engine speed (throttle) and choke engagement from the operator’s console.

Fitment & Compatibility

Before buying, verify your mower model and deck size. This cable fits Cub Cadet RZT-L42, RZT-L46, RZT-L50, RZT-L54, RZT-S42, RZT-S46, RZT-S50, and RZT-S54 models. It is an aftermarket replacement for OEM part 746-05145. Measure your existing cable length—this one is 57 inches overall. Check that your mower uses a combined throttle/choke control (not separate levers). If your model has a different cable routing or a shorter/longer original cable, this may not fit without modification.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic hand tools and patience to route the cable through the deck and console. Can take 30–60 minutes.
• Quality note: Users report it works well but the outer sheath may be slightly stiffer than OEM. Lubricating the inner wire before installation can help smooth operation.
• Common gotcha: The cable ends may need minor filing or adjustment to fit the lever pins snugly. Check alignment before tightening.
• No instructions included: Have a diagram or reference photo of your original cable routing handy.

Should You Buy It

If you own one of the listed Cub Cadet RZT models and need a direct, budget-friendly replacement for a worn or broken throttle/choke cable, this is a solid choice. It’s not OEM, but at this price and with strong user ratings, it’s a practical fix for restoring control without paying dealer prices.
