JD built these Hydraulic lift MCS for several model tractors over the years. The collection container raises hydraulically and dumps when it reaches the top. It will dump into a pick up truck. I picked this one up used. It has category 1 three point connection points, Honda engine that powers the power flow impeller. I adapted it to my quick hitch. JD makes mower deck boots for most of their decks. You just have to find the right one for your deck. Currently I have the hydraulic lines plugged into the FEL quick connects on my 1025r. I plan to mount a single spool open center valve on the MCS and feed it with the power beyond lines at the rear of the tractor. This is still a work in progress.Is there a JD or 3rd party dump from seat material collection system for a 2000 4100 with 54" mower?
