Never heard a complaint on K turbos, I've read where some say it actually conserves fuel but I cannot verify. Really like the turbo engine M8540 over my previous 7040 (non turbo), but it's all good. One precaution my dealership stresses (not to divert this thread to the issue) is to transport turbo engines with the stack covered to prevent pinwheeling (thereby wearing out the bearings w/no oil feed) That said, there are many other variables one could weigh in the choice of models such as size and load capacities of the FEL and 3pt hitch....the decision of M series over the Grand L was a no brainer for me, but the application was more appropriate. good luck, am sure it's a good machine. bb
