Blown head gasket or cracked head or block or if wet sleeve the sleeve seal on one cylinder maybe bad any and all of those can cause that prpblem

One of our 674's started getting coolant in the
oil, it was the headgasket. Both gas tractors.
Has 2500 hours on it, fixed it last winter. This
spring, fuel pump diaphragm let go and filled
the oil full of gas. Time for another oil change,
even though the oil had less than 4 hours on it
since the headgasket change. Good tractor
though.

If it is a Diesel then probably leaking O-rings on cylinder sleeves. Common problem on the older German Diesel engines.

Just worked on the neighbors 574 diesel. Liners and orings were bad. Take the tappet cover off and see if you can see we're the coolant is entering from.
