Hi everyone, I have a YM276D with an diesel problem. While runing the other day the engine slowed down, stoppped and would not turn over on the starter. All fluids are up level and it has fuel. I left it for 4-6 hours and it would it started again, ran for 30 seconds and tightened up again. Used a bar and turned it over backwards for about half a rotation and could turn it the right way very easily. At that point I turned it over on the starter with no fuel and it seemed to go as long as I wanted it to. Tried to start it again and it seized again. Any ideas would be appreciated.

Check all fuel lines, make sure they are tight, look for leaks, bleed air out, then try to crank. Shortly, people that can help you will chime in.
Seems like a plugged filter. Is this a cold weather related problem? If the oil annd hydraulic pumps are gear driven, a plugged or blocked pressure line acts this way. Reversing the crank just runs one of the pump lobes open to releave the pressure (for a while).
Have an experienced mechanic open the engine and look for the reason...there could be several. Continuing to start it or try to start it will not make it better. Seriously, I never cease to be amazed at the volume of emails we get that go like this: "My tractor overheated. I did xyz (even though there was no obvious reason for the overheating, like low coolant) and it overheated again. Then I did abc and it still overheated. What should I do?" My response is that there are probably now far greater/more problems than there were when it had just overheated once. I understand wanting/trying to fix something on one's own (and let it be known that I am NOT a mechanic....I pay good people for that), but too often what happens is simply magnification of the original problem through repeated efforts to just make it go away.
Seriously, seizing is a serious issue. You could easily cause enough $$ damage in additional parts by continuing to try to turn it over to offset the cost of a mechanic tearing into the engine several times. Find a good local mechanic and pay him to pull the head and look at the internals.
