it will save your bacon, get it done.
I did that, but I found out it will drain the whole resivoir of oil through the winter. So I put a petcock like a radiator drain on it, and I close it in the winter.instead of paying deere the couple hundred dollars they want for the parts for the pip, just buy a 5 dollar breather from bumper to bumper, drill a hole in the cover of the reverser valve, and tap it with a tap and die set. works fine.
