Rear Remote Quick Connect Addition

[kthompson]

My question is why is it plugged?

Only thoughts that comes to me is fitting got damaged to the point of leaking and replaced with plug when found out the cost of the Kubota quick connect. ( I had that to happen on of my Kubota's and went with simpler fitting over the push pull design Kubota had for price difference. Still regret that.) Or he only used a single action cylinder on something and wanted to use that valve for some special reason.
