The first 200 hp plus tractor I ever owned and ran was a hopped up JD 5020. It was a wheat land model with the big fenders and all. It had 24.5 x 32 axle duals. I put a M&W turbo kit on it with a homemade inter-cooler. I turned the injection pump up about 50%. I installed a pyrometer, to watch the exhaust temperature. I also just had a straight stack on it.
I had a JD 230 24 foot disk with the cone blades. I could pull it in 5 th gear at 6.5 MPH with the wheels up cutting 6-8 inches. You had to watch the pyrometer like a hawk. If you hit a soft spot that let the disk go over the spools it would shoot the exhaust temperature up in seconds. 1000 plus degrees after the turbo in seconds. I would just feather the disk up a little until the disk was back on solid ground.
At night the whole exhaust system would be cherry red to the top of the exhaust stack. Hit a hard pulling spot an flames would shoot a foot out the top of the stack.
Wow what a beast!!! You could do 20 acres an hour in longer fields.
No cab, loud with the straight stack, and hot and dirty to run. The big rear fenders just seemed to funnel the dust back on you. Your ears would ring for hours after you ran it hard. Man did I think that was a cool tractor. LOL
I did put an muffler on it and turn the pump down a whole lot. It actually did not hurt the total pulling power that much. It would lung and not over heat the exhaust so easily. That tractor was my main tillage tractor for about ten years. After I put the clutch out of a JD 6030 in it I did not have many problems with it.
My boys raised cane when I sold it and got a JD 4840 to replace it. JD 4840 was not as cool to them. LOL The JD 4840 did not have quite as much HP but a whole lot nicer to run. Ran that until about 7-8 years ago when I found a JD 4960 to replace the JD 4848. Big jump there plus gained the MFWD.
It is funny the JD 4960 would eat the JD 5020 in just pure pulling force but that JD 5020 seemed a meaner tractor. I guess the JD 4960 is just too quiet and comfortable to be cool. LMAO.
So what beast tractors have you guys ran or owned???

Today's Featured Article - Grain Threshing in the Early 40's - by Pat Browning. The setting is rural Wisconsin, halfway between East Troy and Elkhorn, on Hodunk Road, our nation was at war, and I was 6, 7 and 8 years old. George was our "threshing neighbor." He was the one with the threshing machine, a JI Case on steel wheels, and he pulled it to our farm with a JI Case standard tractor also on steel. In those days, steel wheeled implements were common. The roads were general gravel, so the lugs cutting into them wasn't a problem. George would set up the thresher, s
