Yanmar Super Expensive?

[rockyridgefarm]

Yea, I'm right there with you fellas. One thing I like about Yanmar is they make horsepower the old fashioned way, by using a bigger engine rather than a turbo.

This is especially interesting because they have plenty of turbo options that would be easily slid into the lineup.

I have been hearing that there is a small turbo'd engine bubble about to burst in the automotive world. Real world usage is nothing like the treadmill numbers. Of course, there are plenty of people happy with their turbos.

This may not be true for tractors but it seems to me a small car turbo can't spin up fast enough to replace the big-cubic-inches instant torque that helps to merge into freeway traffic etc. Rated horsepower is constant-state, the measurement doesn't consider the moment it takes to attain max torque/hp for any given mid-range rpm.

I have been tractoring for almost 70 years, started disking for my dad when I was 9, many different brands, Oliver, International, Allis Chalmers, Massey Ferguson, Fordson, John deere popin John's we called them and John deere Diesels.

3 years ago, with many reservations, I bought a Yanmar LX490, a turboed version of the LX450. Small displacement for the horse power but this has been the slickest engine I have owned. Great on fuel while just puttering around, and ready to work hard when needed. Yes a sudden load will remind you of the difference in displacement but that has been such a seldom thing and otherwise oh my how this thing likes to make horse power for such a small tractor. Pulling a bushhog through heavy fescue will put a tractor in its place real quick, the turbo shines. The turbo engine really makes torque in a heavy pull.

Unless you have some specific load that demands a the instant torque of a large displacement engine you will not notice any shortcoming of the turbo only its strength.

Great input - thx

Good to hear from an old timer with experience....

When we got our 30 inch storm this "spring" my new WR Long 72 in front blade was still in the factory. I used my old back blade and front bucket on the YT235 to get plowed out...worked just fine, but wish I had that front blade to try out.

Hey Geo, do you think that YT235 could handle a 6ft bush hog? Or would you recommend moving up to a YT347/359 for that? Thanks

The EX2900 , (29 hp ) that I purchased for a park handles a 5 foot hog just fine. I suspect the YT235 could handle a 6 footer ok also. If you have the resources and don't need a MMM then move up a notch. i would not hesitate to run a 6 footer off my YT235 though. Geo

I would say a light duty 6 footer would be OK, a Deere MX6 or similar might be a bit much.

I just saw a pic of a friend on FaceBook, who lives down the street, driving his Dad's New Holland TC55D. LS-built tractor, right? There seems to be a lot of comparison of Yanmar and LS in this thread, so that picture made me think of this.

Both our tractors have the about the same loader capacity, the NH just has 10 more HP. We both move around similar loads of firewood in totes or fork lift bags. Anywho, the son came home one day and saw gear oil leaking out the front of the TC55D. The son asked his Dad what he'd been doing, just moving around firewood, but taking it slow. I mean the guy must be 80 or so, and doesn't bounce around recklessly. Anywho, the LS-built TC-55D had to have the bearings and seals replaced in that front axle, and they weren't all that happy about it. I think they said the fix was $1100 or so. Ouch!

Does LS build their own axles like Yanmar does? If they do, I think the Yanmar ones are built better -- mine haven't leaked a drop. Maybe more value for the dollar?

Can't say for sure, but I don't think LS built any of the TC series New Hollands. Believe they were Shibaura made.
