731-06098 Drive System Hydro Fan 10 Blade for Cub Cadet Lawn Mower Transmission Fan LGT SLT SLTX LGTX LT LTX 1042 1045 1046 1050 1054

What It Is

The 731-06098 is a 10-blade hydro fan that cools the transmission fluid on Cub Cadet lawn tractors. It’s a direct replacement for the OEM fan found on select LT, SLT, LGT, and SLTX series machines.

Fitment & Compatibility

Before buying, confirm your tractor model and that the fan is used on the hydrostatic transmission axle. This fan fits Cub Cadet models including LT 1042, 1045, 1046, 1050, 1054, and the LGT, SLT, SLTX, and LTX series. It is a genuine OEM part, not aftermarket. The fan has a 2.5-inch inner diameter and a 5.5-inch outer diameter with 10 blades. Verify your existing fan measures the same—if your fan has 8 blades or different diameter, this will not fit. Check your machine’s serial tag or parts diagram to confirm compatibility; this fan does not fit all Cub Cadet hydro pumps.

Key Things to Know

• Quality: OEM part, so it matches original specs and durability. No fitment guesswork if your model is listed.
• Installation difficulty: Moderate. You’ll need to remove the mower deck, belt, and possibly the transaxle pulley to access the fan. Expect 30–60 minutes.
• Common gotcha: The fan is plastic and can crack if overtightened or if you pry it on. Use a fan removal tool or a puller to avoid damage.
• Replacement sign: If your hydro whines or runs hot, check for missing or broken fan blades. A missing blade can cause overheating and transmission damage.

Should You Buy It

Buy this if you own one of the listed Cub Cadet models and need a direct OEM replacement for a broken or missing hydro fan. It’s a cheap fix that prevents transmission overheating and extends the life of your drive system. Skip it if your fan is intact or your model isn’t on the compatibility list—aftermarket fans may be cheaper but risk fitment issues.
