Runleader HM038AD Digital Hour Meter

So you buy a brand new 54" zero turn only to find out it doesn't come with an hour meter. Thanks Toro! If you want one directly from them its $80 bucks. Buy this one instead. It worked for my Toro Timecutter model 77507. The hold for the hour meter is already there under the vinyl/plastic sticker! Just feel around for it (and maybe watch a YT video on how to do it). The electrical hookup is already there too, the wires are just dangling underneath. After I cut through the sticker I did have to enlarge the hole slightly with a file to fit this hour meter.

Works like it should. Used all summer with no problems

Excellent Fit for Toro Timecutter and the Cost was a small fraction to buying a Factory kit. Less than 20 minutes to install and working great

Works well on my jd l120 tractor but had to splice connector

tl;dr: the documentation for this item does not specify whether this item counts sub-6-minute intervals, but according to my testing, it does (I suspect it accumulates seconds, though it only displays in increments of 6 minutes (tenths of an hour)). Gory details: I was looking for a way to measure the accumulated time that my rooftop Heat Pump runs its Resistive Heater (aka "Emergency Heat" which consumes electric power at a much greater rate than the heat pump operating in its primary reverse-A/C heating mode), in order to ascertain (a) whether (how much) the reverse-A/C heating mode failing to "keeping up" with heating my house (causing the thermostat to turn on the Resistive Heater for backup heat), or (b) how often (how much) the Heat Pump triggers its defrost mode (which causes the Resistive Heater to be turned on while the Heat Pump runs in A/C (cooling) mode to heat its outdoor coils). Such monitoring wouldn't discriminate which of the two above triggers have caused the Resistive Heater to run, but would at least tell me how much of my electric bill comes from running it. Rather than fiddle around on the rooftop unit, I wanted to accumulate the number of seconds (or minutes) that the W2 or E wire at my thermostat has 24 VAC applied (indicating the Resistive Heater is being called for (thus is running)). I searched in vain for a "second meter" or a "minute meter" that would count the accumulated seconds that voltage was present on this wire (NB: in my install, W2 and E wires are shorted together, so there is only 1 wire to monitor). Fortunately according to my testing, this Hour Meter appears to fit the bill almost perfectly: my test was to apply 24VAC across the terminals of the meter for 2 minutes at a time, then remove the voltage for 2+ minutes, then repeat. After 3 cycles of 2 minutes on, 2 minutes off, the counter had advanced from 0.0 to 0.1 (6 total minutes of on-time). After another 3 cycles, from 0.1 to 0.2 (12 total minutes of on-time). The Job Timers feature unique to this particular Hour Meter make it possible to reset the displayed counter periodically (weekly or monthly). I still have to come up with a cosmetic way to mount this above the thermostat. Wish me luck! update: an annoying drawback is that unlike my 2005 Toyota's odometer (which has 2 independently resettable trip meters in addition to the unresettable odometer, any of which (whichever the user last selected) remains displayed indefinitely), after a few seconds this device's display switches back to the unresettable hour counter.

Fit perfect on my 42” badboy riding mower

It works! Stays in when ignition switch is off, not sure if that will drain battery or not. No problems so far.

Working fine

“Hour meter received good quality and very useful. Thank you for your cooperation!”

Fits like a glove, uses the factory plug on this machine, and fills the hole that Toro doesn't put an hour meter in. Put in when brand new so I can track oil and service internals. Works great.

This is a perfect product I was looking for. The delivery was on time. I will recommend to buy this product

I liked the ability to set the total hours, (took a couple of attempts but got there). The two resettable timers just tick away in the background until you want to reset them, so one could be used for oil changes and the other for individual jobs. Good value.

Installed on my generator. Counts accurately. I tied it into a USB charge port on my maXpeedingrods 3500W Portable Inverter Generator.
