The green one is a John Deere 3179DF.. It's the second one ive built this year, and I have 2 more to do.. Under the cover in the very back is an E-6, 2-valve, (ENDT 673) for a B model.. around 1960. both engines are owned by the same people. Funny thing about them.... this is more for youre shop talk thread, but anyway.. I work for myself, and I worked for them at thier company part time, then I went full time for health insurance. So one friday I went home 2 hrs early because I was in a lot of pain, (buldging disc's).. anyway, no one was there but me and I was done with all of my work.. went back on Monday, and the Son, ripped me a new A-Hole, cursed me me out and told me to get the "F" out!!! when I came back to get my tool box, he asked me if I would still be willing to build thier engines at my shop.. I sad, yes... that was on Nov. 1st. I'm still scratching my head... They also have 2 E-7's and an E-Tech that they want me to build... jojo
