- Kubota ZD221
I have a Kubota ZD221 Commercial Mower with a 48" Deck. About a Year ago, I started having a problem with the Mower losing Power; essentially acting like it was starving for fuel or a leak where are could enter the closed fuel system. My Mower would bog down, lose power and run very rough...then start running again as if nothing had happened. I changed both Fuel Filters many times, changed the electric fuel pump, changed the fuel shutoff solenoid, took the entire tank OFF and emptied the fuel then cleaned the tank, replaced the fuel line from the tank to the first filter, etc. Nothing seemed to "FIX" the problem. I loaded up my Kubota ZD221 Mower and took to the Kubota Dealer for Servicing. Roughly $900 US Dollars later, the Kubota Mechanic replaced and re-tightened 2 brass washers at the Fuel Connection that lead to the Injectors...that was all. Imagine my disbelief and disappointment when I brought my Mower home to find that it STILL was doing same thing... only not as frequently as before.
The problem persisted...and through frequent use and trials to troubleshoot, I began to notice a pattern. Once mowing for several minutes or as much as a half hour, the Mower would once again spit, sputter and lose power... especially if I made a sudden turn, hit a large bump or quickly reversed course. I noted that when I topped off the fuel, my mower would sputter for a moment, then run like a Champ for a while before starting the painful process again. Through a process of deduction, I believe that maybe the Fuel Pick Up line within the fuel tank itself has either developed a hole due to corrosion... as I noticed that the Fuel Sending Unit was heavily corroded. Once fuel within the tank has reduced to a certain level, my hunch is that the Fuel Pick Up line is sucking air... which is the reason for the sputtering and poor performance.
I will dismantle my ZD221 Mower this coming Weekend, remove the Fuel Tank, replace Fuel Lines and hopefully also replace the Fuel Pick Up line within the Plastic Fuel Tank... IF POSSIBLE.
Has anyone else experienced a similar problem? If so, HOW did you manage to solve this?
I have ZERO confidence in the Kubota Dealer Service Department because of the previous EXPENSIVE screwing that I took from them without solving the problem. I would be very appreciative of any advise from Other Owners of these Orange Beasts.
