Owen: Thanks for confirming that, I was quite sure they came from factory D-16. At least I knew everthing up to H, 300 etc. was D-16, and couldn't see any reason for the M, SM, 400, etc. to any different. Since I went diesel for heavy pulling in 63 with a 560, the gassers became less important.

However since I stopped farming and the big tractors are gone, I find myself working these little offsets much harder. My tractors are due for new plugs, thus I must try those D-18Y come spring. When I get out mowing, plowing, disking, etc., if the little tractors run away on me, I'll let you know.

What your saying about the progression from D-16 to D-15Y then on to D-18Y makes sense. I just could never figure why these guys liked their D-21. But then I like to hear them working no matter how large or small the tractor. If I wanted an off road sight seeing vehicle I'd buy a horse or a ATV.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par ... [Read Article]
