About this replacement part

Aftermarket replacement deck spindle

FLIP 706751 is an aftermarket mower deck spindle by Flip Manufacturing for compatible Ariens and Gravely mowers. It supports blade rotation as part of the deck's cutting system and is a replacement for a worn or damaged spindle on a compatible mower deck.

Confirm compatibility before ordering

Replacement references are 51537300 and 51530700. Ariens and Gravely list 51537300 as the replacement for the earlier 51530700. These are OEM cross-references, not the manufacturer part number of this FLIP product.

Check your mower's model and serial number, deck configuration, mounting pattern, shaft and pulley interfaces, and blade attachment against your original spindle before ordering. A matching brand or model-family name alone does not confirm fitment. Refer to the listed model information. If any detail differs or is unclear, text photos of the original spindle and your mower's model and serial number to 903-320-4519 before ordering.

Installation guidance

Make the mower safe to service before removing the blade, belt, pulley or spindle. Follow the equipment manufacturer's spindle replacement instructions and specified fastener torques. Check mounting alignment, pulley and blade attachment, and free rotation before operating the mower. Installation requirements can vary by application; contact FLIP if the replacement does not match your original spindle.
