What It Is

A universal digital hour meter that tracks engine run time on any gas-powered equipment with a 5-277V AC or DC electrical system. Designed for zero-turn mowers, tractors, generators, trimmers, UTVs, and brush cutters.

Fitment & Compatibility

This meter works on any machine with a spark plug wire, magneto, or battery-powered ignition. It is not model-specific—it connects via a simple wire wrap around the spark plug lead (no hardwiring needed). Check that your engine produces a pulse (most small engines do) and that you have access to the spark plug wire. Works on 12V, 24V, and 277V systems, so it fits both gas and diesel engines with ignition pulses. No OEM vs. aftermarket issues; it’s a universal add-on.

Key Things to Know

• Installation: Very easy—wrap the sensor wire around the spark plug wire 3-4 turns, then attach the other wire to a ground (battery negative or engine block). No cutting or splicing required.
• Waterproofing: IP65-rated, so it withstands rain and hose-downs. Mount it on the dash or handlebar with the included bracket or double-sided tape.
• Display: Large LCD with backlight for low-light use. It measures total hours (not resettable) and starts counting when the engine runs.
• Accuracy: Works on 4-stroke and 2-stroke engines. May not register on very low-rpm or intermittent pulses (e.g., some small trimmers). Test by starting the engine—if no reading, adjust the wire wrap tightness.

Should You Buy It

Buy this if you need a cheap, no-fuss way to track maintenance intervals on multiple machines and don’t want to splice into wiring. It’s ideal for DIYers who own one or several small engines and prefer a universal solution over brand-specific meters. Skip it if you need a resettable hour meter or a unit that works with battery-only systems (no ignition pulse).
