We were out spraying last week with our self propelled sprayer when it stopped suddenly. The engine appeared to stall as though it was finding running too hard. It would not restart immediately but did restart an hour later and drove home fine though ran hot and appeared to pressurize her water system.
Running at tick over in the yard she gave a constant stream of bubbles in the expansion tank so we changed the head gasket assuming that was the problem. This appeared to fix the problem and after running her up and down the road a couple of times "just to be sure" we set off spraying again. After an hour she did exactly the same again, stopping suddenly and refused to restart. By the time the driver had walked home (no phone!) it was dark so nobody has been back for a look.
My question is could the problem be pump or hydraulic motor related or is it a classic seized engine? I sort of know my way around an engine but the hydraulics are a mystery to me.
She is an Evrard with Poclain hydraulics and a deutz 6 cylinder water cooled engine.
Any ideas gratefully received.
