Exmark 126-3931 Hour Meter Turf Tracer SSS270CSB00000 SSS395CKC00000 S Series

What It Is

The Exmark 126-3931 is a genuine OEM replacement hour meter designed to track engine runtime on specific Exmark Turf Tracer and S Series zero-turn mowers. It’s used for scheduling maintenance like oil changes, blade sharpening, or filter replacements.

Fitment & Compatibility

This hour meter is a direct fit for Exmark Turf Tracer models SSS270CSB00000 and SSS395CKC00000, plus the S Series line (SSS270CSB, SSS395CKC). Before buying, verify your mower’s model number from the plate under the seat or on the frame—this part is not universal across all Exmark models. It’s an OEM part, so no aftermarket adapters needed. The meter face is standard 2-inch round, with 0.187-inch spade terminals. Check your current meter’s connector type; if it’s different, you’ll need a pigtail adapter.

Key Things to Know

• Installation difficulty: Easy—disconnect the battery, unplug the old meter, plug in the new one, and secure it in the same mounting hole. No special tools required.
• Common gotcha: The meter retains total runtime after battery disconnect; if you need to reset it, you’ll have to run the engine to zero out manually (not user-resettable).
• Quality: OEM Exmark part, so it matches the original fit and durability—no concerns with cheap plastic or inaccurate readings.
• Wiring note: Polarity matters—black wire to ground, red to switched power (ignition). Reversing won’t damage it, but it won’t count hours until corrected.

Should You Buy It

If you own an Exmark Turf Tracer or S Series with a failed or blank hour meter, this is the no-hassle fix. It’s pricier than generic aftermarket options, but it’s a guaranteed fit and avoids wiring guesswork. Ideal for commercial operators or homeowners who rely on precise maintenance tracking. Skip it if you don’t need runtime logging or if your model isn’t listed.
