I was wandering around on YouTube a while back and stumbled across this guy and his Kubota L2501 which is now an L3501. I’ll try to make this short and y’all can go watch his videos for the mechanical details and such.
Guy bought an L2501DT, and was disappointed at the lack of power, so he messed with the injection pump and timing to get ~35 hp out of the engine. Apparently this same engine was used in some of the older pre-emissions L series machines that were 35 hp, and Kubota detuned the engine down to 25 hp for the L2501.
Here’s my idea. Obviously a lot of us are not as mechanically inclined as this fellow, and personally, I wouldn’t want anyone tearing apart the engine of my brand new $20k+ tractor. Would it be possible (legally) for tractor manufacturers to produce a 25 hp tractor (L2501, 3025E, Workmaster 25) that could easily be turned up to 30-35 hp, by someone with average mechanical experience, like changing their oil and other simple maintenance? Then you would be able to have a brand new 35 hp tractor with zero emissions equipment. In my mind, technically the manufacturer IS selling a 25 hp tractor. I know it it much more complicated than that, but it’s just an idea I got after watching this fellow’s video.
