Mower life expectancy

What could you anticipate the life expectancy of a quality commercial mower- ZTR, Walk behind, Stander? Just wondering how long it will last before a lot of wear and tear will start nickle and diming you?

I'd say 2000+/- hours. A lot of it is determined by how well you take care of your mower. With good maintenance (oil changes, greasing, air filter changes, etc) and good care, your mower could definately last longer than 2000 hours before "nickle and diming" you.

It goes far beyond what you speak of, I found after 10-12 years the
manufacturers start to phase out parts so it becomes harder and harder
to find replacements and guess who gets to do ALL the cross-referencing?

Also certain parts can NOT be replaced, at least not easily, but they do wear,
unless you feel like replacing a whole deck (they're not cheap).
On account of one stupid little steel PIN that's welded onto the deck in such a way that I don't
foresee most backyard mechanics replacing it, but it's so worn that the spindle it holds wobbles and
this wobble causes the $5 left-thread eyebolt that's part of the turnbuckle belt-tensioner to break
ALL the time.
When it breaks you're SOL unless you've got one already handy, then it takes 5 minutes to replace it,
assuming you can pull the broken off piece out of the turnbuckle easily.
As for replacing the pin, well good luck finding it, even the original OEM parts manual doesn't show it,
no sir, you have to buy the deck.

So in the compromise one has to run the entire machine slower, to keep the wear and tear from eating us alive.

8-10 years, reasonably speaking, but even then...
The mower is fully paid for, a new one costs a LOT more than it did 8-10 years ago...

You'll see

With farm tractors, they make replacement parts for some that go back to the 1930s! So why would they stop making parts for commercial mowers after only a short amount of time. If taken care of, they can last as long as a farm tractor easily!

I couldn't agree more, it ain't right but Toro doesn't even allow the download of their 1997
model 30197 parts manual anymore although granted, it's actually the 1998 manual...
Same with the Owner's manual, it's just not there.
Oh but it's the same thing as the 1998, so is it a mistake?

I think not, try the 30165, that's a 1991 Toro 52" model.
Nothing for that, well...
Almost nothing, they have a FEW parts but not most, good luck even TRYING to find a parts diagram!
A complete one would be nice, I guess there's always some cute volunteer willing to SELL me one now...

Luckily that one crosses to the newer 52" Groundsmaster and I'm not sure what all crosses
but the parts I needed did, now guess who had to figure that one out?

As the owner of a 2004, a 1997, and the recent dealings with that 1991 Toro I can pretty
clearly see the progression of how and where things get quietly pushed out, far as I'm concerned
they don't want us fixing them up, that's probably not good for business.

I was thinking 2000-2500 hours if well maintained.

2000 hours seems about right, but it all depends on the conditions it is running in. Some only last 1200 hours with good maintenance, the heat really breaks down these air cooled engines.

We've had great results with Grasshopper 700 series front mount ZTRs
with liquid-cooled Kubota engines.

1993 721 5,000+ hours (just gave this one to a friend, runs/mows fine)

1998 725 7,130 hours (our backup machine runs/mows like new)

2004 722D diesel 2,400 hours (our primary machine, fully awesome)


No problems getting parts for these machines, I've replaced some hydros on the older machines but all the engines are original
and never any internal engine problems. Zero spindle failures in 16 years.

We love the diesel, it averages .6 gallon per hour fuel consumption.
Our 721/725 gas engines average approximately 1 GPH.

Maintenance is the key to longevity, including blowing off debris and scraping the deck clean at the end of every mowing day,
this really helps to prevent corrosion. I also give the spindles one pump of regular lithium grease every eight hours of use.

P.S. to my previous post.

I'm shooting for 10 years in service/10,000 hours on our 722D diesel,
and I think it's do-able.

I'm using Amsoil ACD synthetic diesel oil and bypass filtration,
with 500 hour oil/full-flow filter change intervals (twice a year for us).
