Good To Know
Q: Can I replace just one spindle or do I need to install all three? A: You can replace a single spindle, but installing the full 3x set ensures consistent wear and balanced performance across the deck.
Q: Will these spindles fit my John Deere lawn tractor? A: These spindles are designed for John Deere X300 and Z225 models; verify your deck uses part numbers M157769, M157736, AM137483, or M159146.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
