Bigted,

Thank your for the concise explanation. It is appreciated.

I have taken off the parts you indicated and taken a good look at the set up. The system seems fairly fool proof and reliable.

In general this seems to be a pretty high quality mower. From what I read the Quattro's are a reliable well built engine. The flymo frame seems really solid.
Time for it to move on to a new home.

What is a fair price for this type of mower? I was thinking around the $150 mark.
