AKfish said:No such thing as a "Free Lunch"! Horsepower or cheeseburgers... you get what you pay for! Much discussion here (and other brand forums) on the 4000 series (and some on the cab model 5083e) of jumping the horsepower with a little "tweak" on the injector pump.
A detailed review of the parts listing's (pump, turbo, injectors) for the different Hp rating on the 4000 quickly illustrates that it's not JUST a set-screw on the pump. It's a whole lot more!
'Course, I don't know about you - but, if I'm gonna buy a NEW tractor - why, why would I trash the warranty right off the dealer's lot??!?
Pony up for those extra horses.

Here she is 5075e with a mx8 cutter. I spent about 6 hours in the seat today and just love it!
