You are 100% spot on correct. Plus if I didn't buy the tractor, I didn't want the owner to feel like he couldn't list it on here.
I did have an hour long phone conversation with a Ben Harper. What a knowledgable gentleman!!
On a side note, I picked up the 318 this morning and brought it home and mowed leaves with it and cleaned it up a little.
An odd thing happened while I was playing... When I pushed the hydro lever all the way forward or all the way aft, the engine dies. Starts right back up but dies in the same way every single time.
The engine only has 590 hours. It starts faster than anything I have ever seen, idles perfect and runs great all all RPM... the only thing happening is it dies when trying to go full speed fwd or reverse.
I did have the mower deck AND 4 way blade on at the time and had been cycling them A LOT.
