2 cyl. VS 3 cyl. engine

[vallyfarm]

Trying to narrow my search down, I was wondering why some models have a 2 cyl engine, and another has a 3 cyl engine. It seems to have nothing to do with horsepower. Ae there any advantages to either engine, better fuel usage, better torque curve, etc. Also, how importaint is transmission choice? I plan on a lot of rototilling, but also some FEL work in the goat barn. Any hints would be great. Mike

I can tell you from personal experience that 3 cyl. engines aren't as loud as 2 cyl. ones. The 2 cyl. might be a little better on fuel consumption. That being said, I have a 3 cyl. and it uses less than half a gallon of diesel per hour of working (mowing or using the loader).

As for transmissions, if you are doing loader work you will find a powershift very nice. A powershift lets you shift gears without using the clutch. I know between HST and gear that you lose some PTO hp with the HST, but I think with the powershift vs. gear that that is minimal.

Mike,

Aside from that wonderful sound a 2 cyl. makes, it is also better on fuel, has more torque and less moving parts than the 3 cyls. If you want a 2 cyl. with Powershift, you need to look at the YM2210.

P.S. What part of York State are you in ? I grew up on a mountain overlooking Elmira, NY

Engines come in many different configurations.

Eg. two cylinder - Inline, opposed, that ugly V harley

Some configurations are naturally balanced, others are not. Usually more cylinders means smoother operation as there are more firing impulses.

RPM limits on engines may depend on bore size and stroke.

Fuel efficiency is dependant on the design.

Noise will be dependant on engine design and muffler systems.

And on and on can go the variables.

To answere your question there is no answere!

My favorite value of all the models we carry is the 2 cylinder 2210. Strong as an ox, whips a comparably sized 3 cylinder all to heck at low RPMs. Only drawback I see is noise, and even the 3 cylinders are noisy enough that the operator should be wearing hearing protection anyway.

Ear protection? the noise is music to my ears....

I have a 3 cyl YM2310 and I love it. Could not bog the thing down if I tried!

You don't really mean that .

I haven't heard many Yanmars and I don't know if my 3 cylinder 1802 is an exception but noise has never been an issue with it. It is much quieter than my Honda 4-wheeler and way quieter than my riding mower and my gas generator. And I can't even hear it running when my neighbor is using his chain saw.

It appears to depend strictly on dates of beginning manufacture. I believe all 3 cylinder models were released after 2 cylinder models, meaning all new tractors after a certain date were 3 cylinder.

My 1602D (3 cyl) is quieter than my ZTR, I don't find it objectionably noisey at all.......the only time I get any diesel knock at all is start up or at low idle, otherwise it sounds like any other internal combustion engine.

But to the first question, I agree - it depends.............

I like my 2210. I do wear hearing protection when on the seat for along time. The same hp engine in 2 cyl will have a touch more torque the 3cyl will be smoother/quieter. The 2 cyl will have two larger pistons compared to 3 smaller ones. This is the reason for difference in torque. I do not know why manufacturers went away from the 2 cylinder engine. Everyone loves the old johny poppers!

Correct Norm. The 3 cyl tractors also have more features. If it was me I would get a 3 cylinder if I was going to do a lot of high RPM work such as mowing. If I was going to do a lot of heavy pulling (box blade, plow, disc) I would get a 2 cylinder.

Thanks guys, 1 more question- which ones have water pumps? all over a certain HP, all 3cyl, or anything like that? Mostly rototilling in med to heavy clay here in N.Y. I'm over by Saratoga Springs. Plenty of rocks for the FEL also. Mike

I don't think I would put that much emphasis on a water pump. Any reputable brand, with or without water pump, properly maintained, should run at its rated horsepower indefinitely without overheating.

And my personal opinion on 20 to 30 year old equipment - the simpler it is, the easier it will be to maintain it in good condition.

The YM3000 & YM2500 3cyl came out in 1977, The YM140, YM146, and YM147 2cyl came out in 1984 and were built until 1989.

Yup, that's why you do what you do, Danny, and I'm retired .

I'm so ashamed!!!!

Don't be ashamed Eugene, they also had the YM122 ( 1 ) cyl from 1984 - 1089.
