3X Mower Deck Spindle for Exmark

Three-spindle set replaces the blade-drive spindles on Exmark 48-inch and 52-inch decks, matching OEM part numbers 116-3497, 116-5138, 116-5712, 109-6394, and 109-8744.

Overview

This 3X spindle set supplies three complete blade-drive assemblies for Exmark 48-inch and 52-inch mower decks, replacing worn or seized spindles that cause vibration and uneven cuts. Each spindle assembly bolts directly into the deck shell and transfers engine power to the cutting blades through a greasable bearing housing. Commercial cut crews and landscape contractors keep this spindle set on the shelf to minimize downtime during peak mowing months on Exmark zero-turn machines.

Built For Performance

• Forged steel spindle shaft resists bending under heavy blade strikes
• Sealed tapered roller bearings handle sustained high-RPM operation without overheating
• Greasable zerk fittings allow routine lubrication to purge debris and moisture
• Precision-machined blade boss guarantees true blade rotation for a level cut
• Painted spindle housings shed clippings and resist corrosion from wet grass buildup
• Set of three spindles covers all blade positions on common 48-inch and 52-inch decks

Specs At A Glance

Good To Know

Q: Do these spindles come with the mounting bolts included? A: Most spindle sets ship with new mounting hardware, but reusing the original Exmark bolts is fine if threads are clean and undamaged.

Q: How often should I grease these spindles during the season? A: Pump fresh grease into each zerk every 40 to 50 hours of mowing, and always after washing the deck, to push out water and clippings that lead to premature bearing failure.

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