    Black tar-like substance in diesel fuel sediment bowl

    I guess so. It's dark black, very thick in viscosity and very sticky. Takes a strong solvent to get all the residue off of the glass bowl or my fingers. I'm glad it didn't get any farther than the sediment bowl in my 730. I had never heard of asphaltenes in diesel fuel, but that must be what...

    Black tar-like substance in diesel fuel sediment bowl

    I have a Deere 2-cylinder 730 diesel tractor that only gets started a couple of times a year. It's been 10 years or so since I used it in the field to moldboard plow a few acres. The last two times I've tried to start it to move it around, I've found the bottom of the sediment bowl with a...

I even used it once at my son's house, pulling it around with his smaller Deere 3046R tractor, but that was...

    Oil & Fuel  4720 erratic no-start condition

    I have a 4720 that I bought new in 2006. It has a little over 1000 hours on it, because its only been used for personal use on my home acreage, as well as occasional grass seeding or spraying on some commercial properties and a farm. It always had a problem with occasional situations where it...
