• Exmark models: ECKA30, ECS180CKA30000, ECX200CKC30000.

What to check:

• Deck size: Must be 30-inch cut. Will not fit 32-inch or larger decks.
• OEM vs aftermarket: This is an aftermarket replacement for OEM Toro part 110-4893 and Exmark part 103-0403. It’s functionally identical but not factory-branded.
• Physical measurements: Spindle shaft diameter is 5/8 inch. Overall height (including pulley boss) is about 4.5 inches. Measure your old spindle to confirm – especially the shaft length and bolt pattern (two-bolt, 3.0-inch center-to-center).

Key Things to Know

• Quality: Users report it’s durable for residential use, with sealed bearings that hold up well. Not recommended for heavy commercial mowing daily.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (recommended 40-50 ft-lbs on spindle bolts), and possibly a puller to remove the old spindle. Blade removal is required.
• Common gotcha: The spindle comes with a grease fitting, but it’s pre-greased. Do not over-grease – one pump per season is plenty. Over-greasing can blow out seals.
• Belt alignment: After install, check blade belt tension and alignment. Off-center spindles can cause belt wear or vibration.

Should You Buy It

If you have a Toro Timemaster 30-inch or compatible Exmark and need a direct-replacement spindle without paying OEM prices, this is a solid
