Hello folks,
Wondering if anyone has had experience in compensating for a missing fuel shut off valve PN AR973R. Ive seen some post from 9 years ago here on this site at this link: https://www.yesterdaystractors.com/cgi-bin/viewit.cgi?bd=jd&th=428805
I dont know if others have just tried a normal shut off valve from tractor supply. I do not know the thread size for the bottom of the tank yet, Im in the planning phases of what I need to buy with this new to me tractor. The fuel shut off appears to be missing the needle valve. See pictures. It would be parts diagram number 8C. Im new to the 720 and I find it interesting that they added a fuel shut off valve at the bottom of the fuel tank as well as the auto fuel shut off sediment bowl. This was an improvement by the Deere engineers at this time for sure so the farmer could shut off the tank without worrying if the diaphragm was worn out and cause fuel to enter your crankcase like it has done to me on my 60. Regarding the 60 I have found that even with using non-ethanol gasoline, the auto fuel shut off diaphragm should be rebuilt once every 5 years to prevent the leakage problem. I used all new parts and only have been getting 5 years out of the diaphragms sadly. Any others have thoughts on the 720?
