FAQ

Is this an OEM Ariens / Gravely spindle assembly?

No. This is an aftermarket replacement-style spindle assembly intended to replace the listed Ariens / Gravely part-number path when the physical fitment details match.

What are the lead part numbers for this listing?

The lead spindle numbers are 59125000 and 58810800. This listing also references 59202600, 59225700, and 59215400 in the same spindle path.

Are 07331067, 09242500, 09253200, 09242600, and 59202300 spindle numbers?

No. Those are pulley numbers and should not be listed as spindle or mandrel replacement numbers.

Should 59114000 be listed as a replacement for 59125000?

Not on this spindle path. 59114000 belongs to a separate short-spindle replacement family and should only be used when the original parts diagram confirms that number.

Can I order by deck size only?

No. Deck size alone is not enough. Match the original spindle or mandrel number and confirm your mower model, deck setup, pulley layout, mounting pattern, and blade path before ordering.
