Mow Ball Bolt Function
The mow ball is part of the lower cutting assembly on applicable wheeled trimmers. The 532180334 Bolt is specifically designed to hold this component in place.
The bolt helps:
- Secure the mow ball assembly
- Maintain the mow ball's intended position
- Keep the lower cutting assembly together
- Maintain the factory component arrangement
- Support reliable cutting-head operation
- Prevent the mow ball from becoming detached due to normal equipment vibration
This is therefore not simply a generic chassis or engine bolt; it has a specific application within the wheeled trimmer mow ball assembly.
Mow Ball Assembly
On compatible wheeled trimmers, the cutting assembly can incorporate components such as:
- Mow ball
- Mow ball bolt
- Carrier plate
- Locking plate
- Locking plate spring
- Cutting line
- Cutting-head hardware
Sears PartsDirect specifically associates 532180334 with related components including carrier plate 594935003, locking plate 532172519, locking plate spring 532173973, and mow ball 532182217 on applicable equipment.
These components are separate parts unless specifically included in a particular package.
Previous & Superseding Part Numbers
The 532180334 Mow Ball Bolt has several important OEM number references:
- 172636 – Earlier part number
- 180334 – Earlier part number
- 532180334 – Replacement mow ball bolt
- 596793001 – Current superseding replacement
Sears PartsDirect confirms that both 172636 and 180334 were replaced by 532180334.
A current Husqvarna genuine-parts catalog, meanwhile, identifies 532180334 as superseded to 596793001.
Therefore, customers searching any of these older numbers may encounter 596793001 as the current service replacement.
Common Reasons for Replacement
Replacement of the 532180334 Mow Ball Bolt may be appropriate if the original bolt has:
- Been lost
- Fallen out
- Become bent
- Broken
- Developed damaged threads
- Become stripped
- Developed excessive corrosion
- Sustained impact damage
- Become rounded at the tool-engagement surface
- Become difficult to tighten correctly

- Mow ball

If the previous bolt came loose during operation, inspect the mow ball and mounting threads for damage before installing a replacement.
