New 5M series

Would like to to hear comments on the 5 cylinder 5030 engine, is this a sleeved motor and any long term experiance. Thinking about a 5065M looks like nice tractor and upgraded features just unsure about the motor.

Few people keep and run the engine long enough to matter if the engine is sleeved or parent bore.

Why don't they keep them? Can't keep um running? . I think a no sleeve engine shows "real progress"

This is really poor that John Deere takes thier top of the line 5 series tractor and puts a non-sleeved motor in. I know if you step up to the 5085m that comes with the 4045 4 cyl. Even thier econo. model 5065E comes with the wet sleeved 3029. Seems like they have something backwards.

I have a hunch these are marketed to the suburbanites and the hobby farmers. Given average care, it would take a long time to wear one out on 150 hours of mowing and driveway work per year.

As for the engines -
I haven't really worked on enough of these motors to get comfortable with them yet. {maybe a half dozen or so injector adjustments}

They are different. I call 'em "John Detroits" - because of the way the injectors work.
