John Deere 1010w compression good or bad?

[Randyhatchjr]

Hi I was wondering if I could maybe get some help here. I am new to the whole tractor thing. I have recently bought a 1961 jd 1010w I am trying to figure out the compression. Research has told me the compression should be 7.9 to 1 . Not sure what that means but I did a compression check and here are my results #1= 112psi #2=115psi #3=100psi and #4=130psi Any help would be great Thanks [/b]

Is this tractor running? Was the test done with a hot
engine ? Throttle wide open ? Oil in cylinders? Shouldn't
have but 5 psi difference overall when testing.

Those are not bad, the 100 is a little low

The engine was cold just putting tester in each plug hole and turning over

I would not worry about it, 116 is really perfect for 7.9:1 compression.
