Which engine would you buy? Dealer said the 3037 would be 1K cheaper so is the LS engine that much better with longer intervals between the regen cycles?
I'm sure you bought a tractor by now, but I just wanted to reply for others who see this.
I'm a mechanic for a LS dealer and in my opinion I prefer the new LS engines over the older Shibarua engines. The LS engines regen a LOT less because they were designed from the ground up to be a tier 4 final engine. The Shibarua is a old mechanical tier 3 engine that was converted to tier 4 interim. I find that the LS engines are more reliable (especially later years as they worked the bugs out) and more powerful.
If you live at higher elevations I definitely recommend the newer LS engines because the computer will adjust the timing for the elevation that your at since it is a common rail system. The other engines have to have the injection pump shimmed, and have more regen issues at elevation due to less air from what I under from other dealer techs. We sold a tractor to a guy a XR4046C at about 6000 feet and ended up trading it for a XR4145C because the XR4046C had no power at all at that elevation.
I doubt their are any new older tractors at dealers anymore, but if there is I would still with the newer ones. If you get a smoking deal on a used one I guess it is ok. But go with the new style if you go new.
The differences between the XG3025 and the new MT225E series is the MT2 comes with a cup holder, and the throttle is electronically controlled. The reason they did that is for European, and upcoming US, emission standards. With the mechanical throttle you get a puff of black smoke when you hit the throttle because there isn't enough air in the engine yet to burn all the fuel. All the electronic throttle does is slow the rev up to help reduce that. It's just like the snap test on the 6.4L PowerStrokes.
Other than these differences there really isn't anything significantly different. LS just really desperate for a nomenclature change.
Thanks for the reply / info. My 3025 actually came with the same cup holder as the 225, also the 3300 loader. It was one of the last 3025s produced.
Walter, yes the only difference between the XG3135 and the XG3140, and the even the XR4100 series tractors, is the ECU software as far as the engines go. They are all a 1.9L 3-cylinder diesel engine. You could take a ECU out of a XR4155 and put it into a XG3135 and make it 55 hp (doesn't mean the trans can handle it though).
But with the new MT2 series the MT230E and the MT235E do not have a turbo. The 40-55 hp engines are the same as in the past.
The engine in the XU6100 and MT5 series is pretty much the same thing but instead it's a 2.5L 4 cylinders instead of 1.9L 3 cylinder. Most parts are interchangeable with is really nice for stocking parts.
And the loader is different between the XG3135 and the XG3140 to raise the lifting capacity from 1700 to 2100 pounds. If I had to guess I would assume they might of just raised the pressures a bit in the loader valve to do that. Or a slightly bigger cylinder.
