Did anyone ever try to see if these suggestions worked and get back to you guys? I'm new and didn't know if I was missing the responce. I am having the same prob with a 6300. The sarter engauges but it is just a hum. The fan turns but r-e-a-l-l-y s-l-o-w-l-y. We had another problem with this same tractor that maybe related but not sure so I need your advice.
The other problem was with start up as well but you had to shake the steering wheel like crazy and hope the battery held out long enough for it to finally crank fast enough to start. It has been down for two weeks now and when I finally got a chance to make it to the field to look at it we ran into the first problem I mentioned. Please help...
...I am willing to try anything but, before I tried all the previous suggestions I wanted you to know both problems.
Also, it has a new fuel pump, the tank has been cleaned out (with clean diesel), new fuel lines to the fuel filter, new fuel filter and housing, and a new nutrual safety switch.
I will wait longer that 8 min for a responce, I appreciate all your help!!!
