Yes I have looked at that manual. Just was saying I believe it is labeled incorrectly
I don't think it's mislabelled. It looks to me like the "24670" is only for the "M18" motor, which was supplied to Ingersoll Rand, not Case Ingersoll, and not Massey Ferguson.

The M16QS engine spec's out to the factory engine in a Massey 316GTX as found here: Massey Ferguson 316Gtx Lawn Tractor Tractor Specifications

Of course, they say it's "77 hp" which I'm confident is a typo. :)

Check out this link.:cool:

Yes, as best I can tell that's M18 out of a 1990 Ingersoll Rand. Not an M16QS out of a (what year?) Massey Ferguson manufactured by Case Lawn Equipment.

I'm not certain, and I'm not claming to be an authority. But that's how it looks to me.

The spec 24670 is identified as Ingersoll Equipment, not Ingersoll Rand. Totally makes sense with the install to the Massey, which used Kohler Magnums twins instead of the Onan used in the Ingersoll branded tractors.

That all makes sense and yes the ARI powered catalogs do identify this as a M18. But equally, the Kohler model coding beginning with 24 also identifies this as a M18. The QS code indicates the "quiet model" and "electric start"

No question you ID tag looks original, though.

Interesting, the M16's, like the K361's before that, are single cylinder models. The M16 model numbering explicitly use codes 7115xx.


So a bit of a mystery there in the M16QS on the label.

We do know there were a few other examples with Vanguard engines where Ingersoll marketed a tractor as 16hp (e.g. 4016), but installed a 18hp engine. The engines were labelled correctly to the engine mfg codes, however. Best I understand, that had only to do with availability of engines, at the time. Another of our manufacturers has made unique little substitutions like that due to availabiltiy, also.

Leaves me to wonder if MF requested unique code labelling to identify the boxer twin as a M16 ... for marketing purposes.

Fun discoveries ...

This, in addition to everything else, is pretty definitive I stand corrected.

Congratulations on your free HP upgrade!

Ok, now that I think about it, I may have something to add. I have a little experience with the Kohler quiet series engines.
In order to get the engine to run quiter, they took a larger engine and governed it down so that it ran at lower RPM. So the larger than necessary engine block/cylinder/piston produced the designated horsepower at around half the "ideal" RPM.

I got a Kohler 12HP "quiet" enginge out of a generator. It's actually a 16HP engine that was set up to run at something like 1800 rpm. These engines can be boosted back up to 3600 RPM and get the full HP out of them, but the carb's themselves are undersized and can't be "adjusted" upwards. In my case I just had to buy a carb specified for the 16HP "loud" version of that kohler engine.

So that explains it: you have a "Quiet" 16 hp engine, which is to say, an 18HP engine that's been inentionally governed down to where it only produces 16HP.

The model as sold is "16hp" while the physical engine code is the same as their "normal" 18HP. As I say, if you want to boost it up to 18HP, you'll probably have to replace the carb(s). You can find info about it on the web.

@tonyjd21 Does the 16HP twin run at this time? At full throttle is it only around 2000 RPM or so?

If it were the factory engine, they surely would have chosen a higher displacement pump for it, since you need to get the standard (about 8 or 9) gallons per minute out of the pump at the "quiet" engine's reduced RPM level.

But if someone just bought a "quiet" version engine and stuck it in there as a replacement, then it's surely mismatched to the pump, only producing 4 or 5 GPM, much lower than ideal. If you did that, you'd find yourself with a much slower tractor than normal.
