5010 vs 5020 John Deere

Most 5010s still running today have been updated to 5020s so its kind of a moot point. However, back in the day when both tractors were new, the 5020 was definitely the better tractor. Bigger fuel tank, better power with better horsepower to weight ratio and more durable engine.

I farmed with a 5010 and it was the most disappointing tractor I ever ran. Looked big and tough and was fun to run but no lug at all. On a 2 row forage harvester my 4020 would run right with it or even out do it. I wished that I would have kept it and added a turbo. Tom
 
The 5010 is in the shadow of the 5020. I've got a 5010 so I can't compare it on a dyno with a 5020. That being said, my feeling is that they're pretty identical tractors, weight-wise and engineering-wise, except for some power and convenience improvements. Both are monuments of John Deere machines for the time. We have fun with the 5010 pulling large implements along side my 4760. Surprising what 2WD can do with 125 HP.
 
My Dad worked for a farmer back when a 5020 was new. The farmer had a brand new IH 1206, farmers brother had a 5010/ 5020. Pulling the same plow on a 1/2 mile long field, the 1206 would lap the Deere every hour. Same with the 4520/4620. Big heavy sow of a tractor that cant get out of its own way

The difference between a 1206 and a 4620 is all in the fuel pump settings. As we all know the JD won the ultimate battle.
 
Both tractors were stock at the time and brand new. The issues with the 4520/4620 is trying to get enough horsepower to move all that weight out that small of a motor
 
I have a 5020 and an IH 1256. My uncle also had a 1256 which he later traded in for a 5020. To say a so called stock 12 whatever can over take a 5020 is BS. And a 4020 keeping up with a 5010 is just as BS.

For starters, I dont care what you think. A 5020 was an under powered pig of a tractor. I dont have time to educate a kid like you about real life. Have a great day!

I'm not familar with the IH 12xx, but I agree it is preposterous to claim a stock 4020 could out-pull a stock 5010, let alone a 5020. It is contrary to common sense and the laws of physics for a lighter, less powerful tractor to outperform a heavier, more powerful one. Fortunately, we don't need to rely on dubious anecdotes for proof, as the Nebraska Tractor Tests tell the real story:

JD 4020 maximum drawbar horsepower: 76 hp at 5 mph (4th gear)

JD 5010 maximum drawbar horsepower: 106 hp at 5 mph (4th gear)

4020 was 95 ho on dyno. You are completely wrong. Nebraska tests dont reflect real world . Look at the weight per hp.
 
It is evident you have little common sense, farming or tractor experience. You have exposed your ignorance. Do anecdotes have no value? Do you understand how the Nebraska tests are performed? Do you understand the difference between lab results and field results? No, you do not. The 5010/5020 were overweight for the horsepower they had. Look at the weight per hp. So if you want to call my Dad a liar, go ahead. You are the one looking foolish, not me.

It seems you and I have different definitions of the term 'real world'. PTO dyno tests do not reflect how a tractor will perform pulling an implement in actual field conditions. The Nebraska drawbar horsepower tests do. Facts versus fantasy, Stuart. It seems you prefer the latter.

As for power to weight ratio, the two tractors are almost identical when fully ballasted. So I don't understand your point.
