Good To Know

Q: Will this kit fit every 48 inch John Deere deck? A: It is built for the LA145, LA155, and LA165 models listed and matches the referenced OEM numbers, but deck revisions exist, so confirm your deck and serial before ordering.

Q: Do I need special tools to install this kit? A: Standard hand tools handle most of the job, though removing a stubborn spindle nut may call for a breaker bar or impact wrench.

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