Weight ratios

For a 'typical' 2 wheel drive tractor under 50 hp (eg Oliver 77 or 550) with no loaded rear tires, would you say that 60% of the tractor's weight is on the front axle? If the ratio is 60% front and 40% rear, how can this be verified?
Do you think the 60 /40 ratio would also work for a similar 100hp 2 wheel drive tractor? Of course the 4 wheel drive tractors would have a different ratio.

A typical 2 wheel drive tractor should be closer to 30% on the front axle and 70% on the rear.
This ratio should hold fairly close regardless of size I would think.

35-40% on FRONT axle and 65-60% on REAR axle is what is weight ratio on most 2WD tractors. heavy tillage tractor might have as high as 75% on
REAR axle.

2wd is 30-70.

MFWD 35-65

4wd articulated 60-40



Ratios stay the same regardless of tractor size, but may
need to be adjusted depending on tongue load of the
implement. This is for in field pulling. Loader work and
mounted implements may vary.

If my old brain can work I think years ago I red where Deere figured about
40% front and 60% rear. But that was just a fleet average some lighter on
front and some heavier. I dought very much if any were 60% on front. The
exception would be a very few made in the early teens of the 1900's that
were only front wheel drive with the engine setting over the drive axle and
on those you could take the rear axle off and hook it up to a blow or disk
bade just for that tractor, if you did not have the machine made for years
with that tractor and tried to pull a horse drawn disk with it then you
could not turn because it would just drag the read axle sideways, Those type
of tractors were only made for about 6 years. The only way to actually know
is go to a scales and weigh both the front and the rear

Find a commercial truck scale and weigh each axle separately

For the ''typical'' tractor to have 60% of its weight on the front axle it would have to have some sort of implement attached to it such as a front loader or front
mounted cultivator. You can easily obtain these typical ratios by referring to the Nebraska Test data on that particular tractor model where each tractor is weighed
including front and rear weight and then just do the math.

I'd say 2WD tractors in general, would be
the other way around. 60 percent of weight
on back axle.

You could verify by driving tractor to a
scale (such as a COOP scale), and placing
one axle at a time on the scale. Weigh
axles separately. Your findings would be
real close (IF) the scale don't have graded
roadway (ramps) leading up to and exiting
the scale. Just a nice level drive through
and over the scale would render really
accurate readings. Of course it wouldn't,
if your on ramped roadway. Parked uphill to
weigh the front. And downhill to weigh the
back. If you have to fight that scenario,
then park your off axle as close to the
scale as possible, without being on it.

Now, tractor pulling tractors, different
story!!! Those guys will rig up thier
tractors, so they weigh MUCH differently.
Probably not uncommon for thier front axle
to weigh much more than the rear. But, they
are playing a different ball game. Pulling
the sled, and the angle of the hook chain,
adds weight to the rear of the tractor
(when they are pulling). So they often
transfer alot of weight to the front to
keep the front down. What they do, varies a
little bit by what rules they are playing
by, and what weight class they are pulling
in. Weight placement is an art to those
people, and they take it serious. They are
on a different wave link than the rest of
us. What they do, is also a little
irrelevant to the rest of us. They are not
trying to accomplish things with a loader,
or mounted equipment, or using the factory
draw bar. Also not using a library of
various equipment. They are just using that
one tractor to do nothing but competition
pulling. Every hook is the same, except for
being on a different track, and slightly
different environment conditions.

All around tractor use and competition
tractor pulling, is by far not the same
thing. So, you likewise want to keep those
2 ideas separated. Although, it is a good
idea to keep tractor properly weighted for
what you are doing. You definately are not
going to want your loader tractor set up to
be a tractor pulling tractor. That's just
not going to work. And that's what I am
getting at.

If you look up the Nebraska test results, many times the weights and splits are given.

I agree with RCP. The Nebraska tests have that information.

For the 77 diesel it was 28% front / 72% rear with 12-38 rears.

I think JD used to claim more weight on
rear in the 2 cyl era but that could have
just been marketing

When trailering my Farmall B and C I usually end up with the rear tires
above the rear axle of my 24 ft tandem trailer. So most of the weight
must be at the rear end.

Simple way to see if what most have said here is do this. Hook up your trailer and measure how high the front of it sits unloaded. Then load a tractor front end first and measure again. Then take it back off and back it on and measure again. 99% of the time I bet you find the front of the trailer lower when backed on and it is not likely to matter what tractor you do that with

I agree with the others, the only tractors I have that have more weight in the front than the rear are rear steer.
