Scag Ammeter Part # 481755

What It Is

The Scag Ammeter Part # 481755 is a replacement gauge that displays the electrical charging status of your mower’s battery and alternator system. It’s designed for Scag zero-turn mowers and commercial walk-behinds equipped with an analog ammeter dash panel.

Fitment & Compatibility

Before buying, confirm your Scag model uses an analog ammeter (not a voltmeter or digital display). This part fits many Scag turf and commercial mowers built from the early 2000s onward, including select Cheetah, Tiger Cat, Turf Tiger, and Wildcat models. Check your machine’s serial number against Scag’s parts lookup—the ammeter is typically mounted in the dash pod, and the connector may be a spade terminal or a push-on style. Measure the cutout diameter (usually 2-1/8”) and verify the gauge’s face matches your dash layout (some have a black bezel, others chrome). Aftermarket replacements exist but often differ in bezel color or connector type; the OEM Scag part ensures plug-and-play fit.

Key Things to Know

• Installation difficulty: Easy if you’re comfortable with basic 12V wiring—disconnect battery first, then remove the old gauge, swap wires one at a time, and secure the new ammeter. No special tools needed.
• Quality concerns: With a 3.7/5 rating and only 6 reviews, some users report the needle can stick or read inaccurately out of the box. Test with a multimeter before final install.
• Common gotcha: The ammeter only shows charge/discharge direction, not exact voltage. If your mower has a voltmeter instead, this part won’t work without rewiring the dash.
• OEM vs aftermarket: The Scag branded part is more expensive than generic alternatives, but it’s guaranteed to match the bezel, mounting holes, and terminal layout of your original gauge.

Should You Buy It

Buy this if you have a Scag mower with a dead or inaccurate analog ammeter and want a direct OEM replacement that fits without modification. Skip it if you’d prefer a digital voltmeter for more precise battery health info, or if your machine uses a different gauge type. For the price, it’s a reliable fix for a common dash failure.
