Nothing wrong with installing one, if you feel like it.
but on the other hand, its pretty useless on a snowblower!
An hour meter's main purpose is to track hours for maintenance, so you know when things need to be done.
For something like a garden tractor, that gets a lot of use in one season, you might want to keep track of hours in case you need to do an oil change and overall lube/grease more than once a season.
that's a good thing to be aware of.
But a snowblower? Unless you own a commercial snowblowing business, the average snowblower will never come *close* to reaching "maximum hours" needed for a new round of maintenance, in one season.
The average homeowner snowblower simply gets its oil changed, and gets its inspection/adjustment/lube/grease job, once a year, whether it needs it or not..
and with that once a year schedule, it is going to have all that work done waaaaaaaay sooner than it technically needs it!
which is a totally good thing..we *should* be doing all that once a year, its very good for the health of the machine.
but..on an hour basis, we are doing it way sooner than the machine really needs it, from an "hours of use" perspective.
And that is why 99% of snowblowers never have an hour meter!
its because they simply don't need one.
but again, if you feel like it, just for your own curiosity, nothing wrong it at all!
but it has no actual practical use..
you should *not* go two, three or four years without doing an oil change or that other annual maintenance, just because hours of use are low in one year, that would be bad.
