Oliver 1855 vs. White 2-110 Max Drawbar Pull

Was looking at max drawbar pulls for an Oliver 1855 and a White 2-110 and found the 1855 could pull more despite a lower drawbar HP rating. What accounts for this? Just courious.

Maybe the Oliver weighed a little more and had a size bigger
tire for more traction? Or the fact the weren't in the same
gear? Either way I bet they ran outta traction before power.
 
Tractor House information is incomplete and sometimes inaccurate. Look up the actual Nebraska Tractor Test for each tractor and compare them. Note that the tests were done on dry concrete and maximum wheel slippage was limited (15 percent maximum slippage?).

As time went on tractors were built more for higher speed field work rather than heavy straining at horse drawn speeds. Manufactures gradually stopped over-weighting tractors during testing to achieve the maximum drawbar pull at inefficient field speeds. Operators manuals often state maximum weight limits and suggest limiting maximum drawbar pull to a specific gear and higher.
 
Without looking up the actual test, what would a 2-110 max pull? I am guesssing with the increased HP maybe around 13,200lbs. Don't the 1855 and 2-110 share a similar rear end which would be a limiting factor.

The White has a cab pictured. The cab will use more energy which means bigger alternator. If I turn on the Air Conditioner in my 94 PTO HP JD it noticeably drags the motor down. Also hydraulics in that era continued to increase in pump pressure, & GPM output. That will use more HP just to run hydraulics. As stated before... Check the Nebraska Tests!
 
Like was mentioned look at the complete test. Remember Horse Power also deals with speed. I remember when I was in high school a man from the University of Nebraska came and talked to our Ag class. He gave us all a copy of the test for a John Deere 520 which was new at that time. What surprised us all was maximum drawbar horse power was in either 5th or 6th gear. Why not in the lower gears, He explained it did pull a lot more, but was not going fast enough to make good horsepower. Compare the 2 test and see what the MPH was in each case.
 
NEB. TEST # 1040, 1855 Oliver diesel, wt. 14,800 lbs. two wheel dr.
Drawbar pull 6680 lbs. [u:514b50413b]@ 4.64 MPH[/u:514b50413b], @ 6.79% slip

NEB. TEST # 1468 110 White diesel, wt. 13995 lbs. front wheel assist,
Drawbar pull 5430 lbs. [u:514b50413b]@6.57 MPH[/u:514b50413b], 3.49% slip, Front wheel dr. [u:514b50413b]engaged[/u:514b50413b].
Also noted, pull of 5494 lbs @ 6.39 MPH, 5.76 % slip, front drive [u:514b50413b]disengaged.[/u:514b50413b]

[i:514b50413b]Note the MPH differences, also the 1855 developed 82.65 max drawbar HP, the 110 developed 95.07, max DB HP [/i:514b50413b]
 
I have had both. The White is a little nose heavy with the heavier tub and engine, the 1855 really puts the hp to the ground, good pulling tractor. You would think the 354 Perkins would outpull the 310 turbo Waukesha but not necessarily.
 
A lot of little details make the difference, one big one is what tires did each have? Maybe GY Traction Sure Grip on the 1855 and some other GY or Firestone on the White! All makes a difference and then Tractor Data is a terrible site to get accurate info!
 
Say what you will about the 310, but a properly built 310, in either 1855 or 1955 configuration is a pretty impressive engine from a performance standpoint in stock trim. I currently have an 1850 and we did have a 2-105 for a while. Really liked that 105 and wish I still had it, but the performance of the 105 just would never quite match the 1955. There were a couple of other 105's around the neighborhood and I was of the same impression of them. Pop sold one 1950-T and it was put up against a 4320 on a forage harvester. The 4320 simply could not match the T's performance either. This is all subjective of course, so take it for what it's worth.

I've always wondered what the legacy of the 55 series turbo 310's might have been if they had been built properly from the git-go.
 
The tests shown above were compiled from the Nebraska tests but didn't point out that the 11487 lbs pulled by the Oliver were with ballast and the 9500 lbs pulled by the White were without ballast. Reason was- White only tested without ballast whereas Oliver was tested with and without ballast. The Oliver's max pull was 9113 lbs without ballast. Just poke "PDF file" under each of your listings above and you'll see what I mean. Tell me if you see something interesting about those two tractors from the test results.
 
Do not doubt that the 4320 came in second on forage harvestor. I am pretty sure that the 4320 like a 4020 was rated for full power at 2200 engine rpm but either 540 or 1000 pto rpm was at 1900 engine rpm. That was fine a a lighter load but not so much when you wanted full power on a 1000 rpm application.
