Again ... I don't have this tractor. This is just a conversation to see if it can easily be done, to see if jumping up in engine size is worth it.

- 2014 LS U5020C w/ LL5100 Loader
I turned up the fuel pump on my LS U5020C (Mitsubishi engine) last March and don't regret it for a second. The improved responsiveness and lack of engine lack is very noticeable. It allows me to do the same work in a higher gear and less rpm.
Have you considered a skid steer loader? It seems from your post that it may suit the work you do a little better and with impliments run via hydraulics.

Actually, a tracked SS is on my future acquisition list for my business, so I can get a little heavier into lot clearing. Something like a Cat 277c, or ASV100, etc. But for now, all of my implements are 3pt driven, and they do the jobs effectively enough for now.
My goal is to have a SCUT tlb, my midsize HST CUT, and the tracked SS. But for this one more year, I'll just have the CUT. Only occasionally, when stump grinding or heavy grading, could I use more HP. Of course, I could always use a tad more loader lift, mainly just when moving pallets, but my loader warranty will be up next month so I may look into adjusting that a touch.
So anyhow, I'm just trying to figure out if it would be worth it to jump up to the 3 liter engine over my 2.2 liter, if that 3 liter could be tuned to run at 60 horse like it is in the 1660. That would be a 25 percent jump in HP from my 1648, which would probably equate to about 8-10 hp at the PTO.
Lol, these are just off season thoughts for the winter time!

Just a thought - if the HST is not offered on the ~55 or ~60 HP MS 16XX trators and only the ~52HP version, perhaps the HST tranny is only designed for max ~52 hp. Otherwise, why would it not be an option?

I would imagine it has more to do with their sales team assuming that people wanting over 50 HP would be using it more for farm use and would prefer shuttle/PowerShuttle.
But I suppose you could be right.

This thread got me thinking of the kioti ck line up 3 tractors same frame 3 different hp ratings. 28/30/35. They do list different cubic liters for each so I don't think turning up pump is what they do. I have a hard time understanding why they offer such close options.
Another thing in hydrostat models all three use same pressure relief setting I believe. I wonder if you're massys are the same.

Based on reliability research done over time, regardless of manufacturer, in any given family of tractors that share basic major components except for modifications to accommodate increased power, there is a degradation in reliability as power increases.

Any links to that research?
I would like to see this research myself! I would especially like to see the information gathered from the designer who told the researcher exactly what the parameter of each engine design was originally to be and how they were told to factor longevity into their design. Simply put base the design on cost or a balance between cost and function or build it to last no matter the abuse it is subjected to. There is a big difference between stretching a designs limits and having slight variations of power output based on the components abilities.
Simply said if its built for 50 Hp and your only going to tune 40 hp in some variations your hole theory is blown out of the water!
