HI all, new here I have a question. I have been working on a John deere F620 and it loses power and shuts off. It also just doesn't seem to have the power it use to have. When you trun the pto on it takes about 10 seconds or so then it shuts off when you try to drive it. If you trun it on and let it set in one spot it when run but its like it has no power. You can also drive it around all day with the pto off, but it still seems to have a lack of power.
My first thought was it must be a safety switch I tested all of then and they where good.
I put my tachometer on the tractor and it was running 6000RPM at wot. I did a compression test on one of the cylinders and it was 110psi a little lower then I would like it to be but I can live with it. The gas tank is in the way so I didn't do the other cylinder.
I went to do a fuel pressure test and of course my gauge decided not to work so I put a fuel pump on it any way it was only $20. It acted like it was runing out of fuel when it shut off so I thought that a fuel pump might work.
My battery is dead so I haven't tryed it after I put the fuel pump on.
All the pulleys on the mower spun freely too.
it has blue spark on both cylinders.
I'm just chasing my tail on this one any one have any Ideas.
