Good afternoon everyone, I was looking at a 720A Series IV grader today, thinking about buying it. The only issue it has is there is engine oil getting into the transmission. The current owners have replaced one of the pumps is somehow connected to the transmission. Has anyone seen this issue or know how the system works? The machine is in good shape and I know the owners and some of the history on it. I’m considering purchasing it if it’s not too difficult a repair.
