Good To Know

Q: Will these spindles fit a 52-inch deck on earlier models? A: They are designed for Ariens and Gravely models listed; double-check your mower’s serial number against the part number 51537200 to confirm.

Q: Are the spindles pre-greased? A: Most units come with a factory grease charge, but it’s wise to verify lubrication before installation for maximum bearing life.
