Rotary Spindle Housing

This housing is designed as a direct replacement for part number 174358. We recommend checking your mower's owner's manual or the sticker under the seat to verify your specific deck model number matches the compatibility list for this part.

You likely need a replacement if you notice excessive vibration, unusual grinding noises while the blades are engaged, or if the blade itself feels loose or wobbly when the mower is turned off.

No, this is the housing unit only. It is intended to replace a cracked or damaged housing, so you will need to reuse your existing spindle shaft and bearings, or purchase them separately if they are also worn.

It is a moderate repair that requires basic hand tools, such as a socket set and a wrench. You will need to remove the mower deck to access the spindle assembly, so plan for a bit of time to safely lift the mower and perform the swap.

If the housing itself is cracked or warped, new bearings will not seat properly, which leads to misalignment. Replacing the housing ensures the spindle shaft stays perfectly centered, preventing further damage to your deck and ensuring a clean cut.
