More Mecum Ribbing

I am just curious what people think, which tractor has more torque, A 60 JD, with 40:24 hp, or a super H Farmall with 33.40 hp?
 
Well,old weldor are u sure, I know my old Deere friends say we dont need no shift on the go, we have our torque built into the engine. Well not true,This should be a fair comparison for a JD guy but the Deere 60 starts out at 1,000 rpm crankshaft speed and has 229.4 Ft Lbs and max's out at 653 rpm, and 251.3 Ft Lbs. Ok a 9.5% increase.The super H starts out 1650 rpm and has 233 Ft Lbs, peaks out at 266.9 Ft Lbs at 1046 rpm on the cranshaft. A 14.4 % increase. I would of loved to have Pete 23 weigh in on this. All data taken from Nebraska test.
 
I haven't looked at the Nebraska tests but with that H reading it would be putting out 73 horse power. Torque x rpm divided by 5252 = horse power. I think you are reading torque at the pto or belt pulley and rpm at the engine. Haven't done any other math for torque rise on either one.
 
Well Nebraska test said the Deere 60 had 40:24 and the Super H had 33:40. And they said the torque was tested from the PTO.
 
Hay, this is all new to me too, But the peak torque of Super H engine rpm, is at 1046, the pto speed would only be 342 x 266.9 = 91279.8 divided by 5252=17.38 hp @ 1046 crankshaft speed.
 
Have to agree. The BTO I worked for off&on for ten years would stick me on an old 60 sometimes. That or an old worn-out A. The 60 was a real dog, hard to believe it was rated 40 HP. One day he had me rotary hoe 80 acres of soybeans with his 6-30 rotary hoe & 60. FORTH GEAR, 4.5 mph... Took me all day! I'm sure my Super H could have pulled that hoe in 3rd, 5 mph. I know the 60 couldn't pull it in 5th, 6-1/4 mph, I tried!

Always been my experience that the great 2-cyl lugging ability only comes into play at rpm's so low as to be worthless, and if you use that torque at those low engine speeds you risk broken crankshafts, or wallowed out flywheel splines, becomes lugging tractor abuse.
 
just goes to show that the two cylinder torque rise is in the owners dreams. they always thought they had a lot of torque because they were always lugged down.
 
Randy, I think you said it best, I cant believe it either ,the Deere 60 only has 16.8 hp, when it peaks out at 653 engine rpm. Its all fun !!
 
Well, the 60 outpulled the Super H in both drawbar and belt pulley tests at Nebraska, but the Super H outpulled the 50, but the 70 outpulled the Super M, but the 400 outpulled the 70, but the 720 outpulled the 400 and the 450, but the 560 outpulled the 720, and the 4010 outpulled the 560 and the 806 outpulled 'em all..........and, and, and.....
 
OK, do you think a stock Super H wheel weighted to 7500 lbs. can pull more than a stock 60 wheel weighted to 7500 lbs. at the same speed....1st gear in the Farmall and 2nd gear in the John Deere, is about as close as you can get...right down to engine stall out? Or 2nd in the Farmall and 3rd in the John Deere maybe...

How did the weights of the tractors compare that were pulling the rotary hoe back then? As I remember 60's weighed about 1500 more lbs than Super H's on the average...of course they could nave been weighted up to weigh the same, but were they? I ask this because I've always noticed that light tractors pull light loads better than heavy tractors do....but light tractors have a lot of slippage and power loss pulling heavy loads that heavy tractor handle quite well.

About 30 years ago I put my 4 row International cultivator on my neighbor's Super H that I was considering buying. The Super H was really a nice one with good power, but it had a he--uvva time in hills with the same cultivator my Super M handled quite easily any where and on the level it was all the SH wanted in 2nd gear, but it did fairly well, but wouldn't pull any hills to speak of and I had to "cheat it up" a little.. The Super M would haul it in 4th if I wanted to go that fast and up any but the steepest hills. A friend with a 60 used a 4 row cultivqator okay anywhere he wanted he said.
 
That 60 was very sick if it couldn't pull a 6 row hoe in 5th. My 51 A Used to pull a 15 foot hoe (6row 30") with plenty of power to spare. Last spring my 630 pulled a 20 foot (8row30") three point hitch hoe in fifth easily. Tried it in 6th with the 630 but that was a bit too much.
