My Ford diesels will not run with back pressure. I got the wrong muffler at TSC once, made for an IH tractor and you couldn't see through the muffler from end to end. Knocked the baffle out where I could see through it to get it to work but it was useless as a muffler and found the right Ford spec. muffler (you could see through) and the engine ran fine.
When I had my cosmetically restored '79 JD 4230, it had a stupid little 1 � outlet on the muffler for a 100hp, 400 cu in engine. Drove me nuts. So I took it off and installed a 4" dia chrome after market pipe without a muffler. The exhaust manifold outlet on that tractor was large because the 4430, the 125 hp version of that machine used a turbo to get the extra 25 ponies.
Loved to take that big 6 to parades with flags all over it, idling along listening to that sweet music. Bystanders liked it too. Got a lot of thumbs up. When working it, I usually wore ear protection even though the Sound Guard cab helped. Sold it when I downsized my farming operation.
When I was a teen growing up, my mechanical mentor said the same thing about not to run the engine hard without exhaust manifolds attached and told me a story about having it happen to him. I never attempted to prove him wrong. Wasn't worth it.

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
