Good To Know

Q: Will this spindle fit my Toro LX425 with a different deck serial number? A: This spindle is designed as a direct replacement for OEM part 112-6063, but deck design variations can occur; we recommend checking the existing spindle part number and deck model stamp before ordering to ensure a match.

Q: Does this spindle come pre-greased and ready to install? A: Yes, the sealed bearings are factory-lubricated and require no additional grease, so you can install the assembly directly onto the mower deck and attach the blade without further maintenance.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
