I bought my 757 new in 2005. it has been flawless until this exhaust valve guide coming loose. It has been a good machine.

Kubota will be discontinuing the 31hp mower so they don't have to do that. Hear talks of a stroked 26hp version to better handle a 72inch deck. Honestly the 26hp regular diesel is about like a 33hp gas in terms of torque so I'd have no issue running a 72.

The reports on the Tier 4 diesels in farm tractors have been that they get BETTER fuel economy.

I still don't want a Tier 4 diesel and I'm glad that my tractor is a Tier 3 just because I don't trust these new emissions systems to stand up to the test of time. I hope I'm wrong, but I don't want to be the guinea pig.

Gopappy, Ive heard that if it has the DEF fluid then it helps it get better than the diesels with only the dpf filter, but still none is as good as no emissions at all which is what they currently have.

The grasshopper I can run at least 50 percent used motor oil in it, I have not tried it on the kubota and won't till its out of warranty. I hope to get 8000+ hrs on the kubota before I have to replace it. I know the motor is good for 12000 hrs in the wrong hands. My kubota uses about 3/4 gallon a hour and you would need a 35 hp gasser to keep up and then you would pushing 2gpm. So fuel pays for itself. I figured in 4000 hours the difference in fuel should be about $16,000. Some dealers say, "well the maintainance cost offsets the fuel". Oh really? My grasshopper has had 0 engine issues in 18 years and 1800 hrs that and the new diesels you change the oil every 250 hrs. Maintenance cost is lower with a diesel. No valve adjustments, no carb issues, no nickel and diming crap. I had to replace the starter and alternator that's it.
