Worked in hustler
My Hustler Raptor SD had the hour meter whit at around 400 hours. I noted it in my maintenance logs and bought this new meter. Dropped right in, plugged up just like the old one. Can’t complain

Works on a 2023 Bad Boy MZ Magnum
The OE tach/hour meter has an internal battery that goes dead after a while like any battery. This one is no different but doesn't have a tach function. I never used the tach anyway. Just plug the one wire that comes from the inductive pickup onto the terminal shown in the ad on this sellers page and it works perfectly. It's supposed to alert you at 50 hour intervals to change the oil as well. Fits the cut out in the panel perfectly.

Plug-n-play for Generac GP5500 AC generator
This item fit nicely in the OEM cutout for the original Hour Meter, on the Generac GP5500 AC generator. Ran the generator for just under 5 hours and got 4.7 hours on the LCD hour meter display as expected. Plugged it in using the original Generac wiring connections. Hour Meter comes with a template sticker to cut a new hole in the operations panel if needed (I used existing OEM cutout). Hour Meter also comes with instruction manual and 2 wire crimp on connectors if needed. I wired the Hour Meter directly to the existing Generac connectors and had no problems. Plug-n-play. Arrived quickly (2 days) via USPS mail, that was another plus. Price was $17.59/each. Preset reminder at 50.0 hours of operation - to change the oil. Always check the oil level in your generator prior to use... or hope the LOW oil level detector works and shuts down your generator before damage occurs. Amazon product description: Runleader Digital Maintenance Hour Meter,AC/DC 5V to 277V for ZTR Lawn Mower Tractor Generator Motorcycle RV Motorhome Milling Machine etc. Time will tell how long the hour meter lasts before the on-board battery crashes... so far so good.

This meter quit running after 8 hours! Mower always parked in garage
Meter stopped working after 8 hours. UPDATE : Runleader has made contact with me, and wants to replace the meter, check serial #, and batch. I believe they make a good product, and are trying to do the right thing. Last update: I received my new meter 2 days ago, it is an easy install, appears to be working fine. Hannah and the service team are excellent. I would buy again from this company.

Works for my Toro Timecutter 75750
Added to my 2023 Toro Timecutter 50" 75750. Mower already had the wiring in place from the factory as well as the cutout for the hour meter under the side panel sticker. 5 minutes from start to finish! Has been working great for the past two months. Now I can keep track of hours for my maintenance.

Compteur d'heures
Installation sur la tondeuse Zéro Tourne TORO 50 pouces Model 75755. Le compteur s'est bien installé puisqu'il y avait déjà un trou prépercé pour le compteur, mais j'ai dû donner un très léger coup de lime pour permettre d'insérer le compteur dans le trou. Le filage électrique était en place. Facile d'installation, et ce, en 5 minutes. Pour une installation plus facile et rapide, il suffit de dévisser une seule vis pour enlever le couvercle qui donne un meilleur accès au filage et à la connexion. Le terminal étant déjà en place, je n'ai pas eu besoin de terminal fourni avec le compteur d'heures.
