2 tractors go head to head: 1) an Oliver 950 gas 6 speed, nearly new 18.4x34 tires, has about 63/64 drawbar HP, and weighs about 10,400 with driver. 2) Oliver 1755 diesel, half worn 16.9x38's, about 75 drawbar HP, but only weighs 8500 with driver. The track is hard packed clay (not worked), and a flip of the coin determines who pulls first. Both drivers have some pulling experience but not much.

What do you think the outcome would be....and why?
 
At 10,400 pounds and 8,500 pounds the heavier tractor has a 22.3 percent weight advantage. That would be an awful lot to overcome.
 
I agree, the almost 2000# advantage of 31 will more than make up for any perceived advantage that #2 might have. No contest...#1 wins.
 

Okay, I will bite. I like the narrow, worn tires on number 2. However, before I commit can you tell us how the tractors are weighted? For example, the percent weight on the rear wheels?
 
Ken, Moresmoke... The tractors are just "stock" farm tractors. The 1755 may have a weight or 2 on the front but I'm sure it has a pair of weights on each side on the rear with standard cast centers. Probably a 60/40 split on the weight. The stock drawbar for it would be the normal hight for farming, 18 - 20" (as a guess).

The 950 has heavy (1500# each) cast rear centers and no other weights. Weight split might be 65/35. Drawbar height would be about the same, 18 - 20".

Thanks to all who have replied.
 
I'm leaning towards the 1755. There are still too many variables, but I like the older shorter lug tires. In slow speed pulling, HP doesn't really matter - traction wins every time. Now if you took those 2 tractors out in a field with loose ground, and hooked drawbar to drawbar, the 950 walks away with the 1755!
 
Are you talking head to head in the same weight class? What speed limit? 1755 hands down, because of the hydraul shift 3 spd.
 

I believe it is possible for the 1755 to be the winner.

As posted before I think the narrow tires with worn tread/harder rubber is a postive. 17% additional HP can help depending on allowable speed. Now, to the weight advantage of the 950, which has an extra 1660 lbs on the rear wheels. However, the two tractors are within 240 lbs of weight carried by the front tires. The 1755 has weights on the front end. Assuming the weights and bracket weight 200 lbs and guessing at some dimensions it can take 600 lbs of down force on the drawbar to carry those weights. The weight is there if the tractor is balanced a little better than the 950, it should be possible for the 1755 (lighter) tractor to win.

And, I tend to be a sucker for the under dog.
 
Thanks for all the comments guys.
This "pull off" would be with the same weight on the sled, all the sled has. We usually pull in either 1st or 2nd gear, depending on the driver's preference. The 950 can't take any weights up front as there are no mounting holes in the frame, and it seems to be heavy enough. I've only seen the front end come up once and then only for a few feet and it settled back down.
Our pulls are just for fun, no money or trophies, just bragging rights.

From the comments it looks like it could be close.

Thanks again!
 
A long time ago I was pulling a 4010 JD. In the 12000 na. Class. Then they went to a farmer 13500 class. I had my drawbar where it was supposed to be. 20" high. And in as close as possible. With a D ring. Also my weights 2 ft or more pushed to front. 3000 rpm gov spring in pump. I could regularly beat your average tractor off the farm. With the 1500 lb. Weight disadvantage. My tires weren't cut, but road worn just right. 18.4X38.
 
If these are straight out of the field not veterans of the track, I would take the tractor with the 1900 pound weight advantage any day.
 
950 easy, although power might be an issue for it even in low gear at that high of a weight. I've pulled one at 8500 a little bit and it lugs pretty good and even that light I had to stay in 1st hence my concern.
